Hurricane Earl Post Storm Report and Analysis Including Link to Eastern Region Communications Test Results
Hello to all…
The following is the post storm report and analysis on Hurricane Earl and his impact to the Caribbean Islands, North Carolina, Southeast New England and the Canadian Maritimes. Hurricane Earl was the second major hurricane of the 2010 Atlantic Season with the first being Danielle and Danielle was a system that only affected shipping interests out at sea.
Earl passed through the Northern Leeward Islands, Virgin Islands and Puerto Rico on Monday August 31st, 2010. The storm’s worst effects were over St. Kitts, St. Maarten, the British Virgin Islands, and Anguilla where an 88 MPH measured wind gust occurred before the wind instrument malfunctioned. Earl downed numerous trees and power lines with some minor structural damage noted. Rainfall of 7-9″ was common over this area and into Antigua where a 45 MPH measured gust was noted by an Amateur Operator on the island. Cars stuck in flood waters from the rain were reported along with storm surge issues on vulnerable portions of the islands. A 60 knot measured wind gust was recorded on the US Virgin Islands as well. Amateur Radio Operators and the stormcarib.com storm blogging network were critical in obtaining reports from this area.
Earl would traverse the open Atlantic Ocean waters northeast of the Bahamas before coming within 125 miles of the mid-atlantic coast of Eastern North Carolina where hurricane warnings were issued for Eastern North Carolina and the Outer Banks with tropical storm watches and warnings north and south of portions of Eastern North Carolina and the Outer Banks of North Carolina. During this timeframe, Hurricane and Tropical Storm Watches and Warnings would be issued over the course of Wednesday and Thursday for portions of New England. Earl was a dangerous Categrory IV hurricane at the time. The forecast was only for slow weakening and the storm to pass within 50-100 miles southeast of Nantucket Island and as a strong Category II to Category III hurricane. Given a system of that magnitude, it was expected that the system would stay fairly symmetrical and while Southern New England would be on the side of the storm with weaker winds, high sustained tropical storm force winds with hurricane force wind gusts were expected particularly in the area of the hurricane warning from Plymouth to Westport Massachusetts including Cape Cod and the Islands. Areas west and north of this region were expected to see tropical storm force winds in gusts and possibly low-end sustained tropical storm force winds.
As Earl approached North Carolina, Measured sustained winds to high-end tropical storm force with hurricane force wind gusts were recorded with storm surge in the 2-5 foot range. Rainfall was largely under 1″ except in the outer banks of North Carolina where 3.5-4.5″ rainfall amounts occurred. Earl’s eye would never make landfall in the outer banks of North Carolina and would stay offshore within 125 miles of the Outer Banks. Over the course of this time, Earl weakened considerably going from a Category-IV hurricane on Thursday Morning to a Category-I hurricane by Friday Morning due to southwest shear and dry air intrusion into the system. This was expected on Wednesday but instead the system intensified which raised concerns that Earl would affect the region as a stronger system but on Thursday these factors finally took their toll on Earl. Due to the rapid weakening, this made the storm that much more asymmetric and a much weaker system as it affected Southeast New England Friday Afternoon and particularly Friday Night and this meant the heavy rain would be along and west of the center with most of the wind along and east of the center of Earl with weaker winds to the west of the center. It is noted that non-tropical models had a better handle on the weakening wind field on the west side of the system and the asymmetry of the system. Also, while the system was moving at about 20 MPH, this is not the noted acceleration of historic New England hurricanes of the 1930s-1950s or even Hurricane Bob in 1991 and Hurricane Gloria in 1995 which moved at rates between 30 and 60 MPH. This meant more weakening due to cooler water temperatures despite those water tempratures being warmer than normal and the shear and dry air over the system also had significant impacts on Earl. Earl would weaken to a tropical storm as it made its closest approach to Southeast New England resulting in hurricane warnings being changed to tropical storm warnings over Cape Cod and the Islands late Friday Evening after the Hurricane Warnings were changed to Tropical Storm Warnings over the Hull to Plymouth area and from Woods Hole to Westport, Massachusetts late Friday Morning.
When Earl approached, winds only reached low-end tropical storm force criteria on Nantucket Island with tropical storm force winds in gusts over South Coastal Massachusetts and Cape Cod. Measured wind gusts of 42 MPH were recorded on West Island Fairhaven, 41 MPH on Marstons Mills section Barnstable, Massachusetts, 44 MPH measured gust on Marthas Vineyard and 41 MPH measured gust in the Siasconsett portion of Nantucket Island. Storm surge from swells closed some shore roads in Newport, RI, Dennis, Mass. and threatened some homes with flooded beach areas in the Madaket section of Nantucket Island. A couple of isolated 50 Knot gusts were seen at the elevated platform at Horseshoe Shoals Nantucket Island and at the Kalmas weather station in Barnstable, Mass. via weatherflow with a 54 MPH gust measured at Nantucket Airport along with a sustained wind of 41 MPH. The winds downed isolated trees and caused isolated power outages in Chatham, Dennis, and on the Bourne/Falmouth line.
The bigger story was heavy rainfall with 2-4″ with isolated 6″ amounts occurring from West Island Fairhaven through Barnstable County, Martha’s Vineyard and Nantucket Islands. This resulted in urban flooding over portions of Cape Cod shutting down a few roads and intersections. The combination of storm surge and rainfall causing minor street flooding issues on Nantucket Island. Several flooded basements were reported on Martha’s Vineyard Island in Edgartown and portions of Cape Cod. Rainfall in the Greater New Bedford area west of Fairhaven through South Coastal Rhode Island and up through Taunton were between 1-2″ of rain with amounts 1″ or less over the remainder of Eastern Massachusetts, North-Central Rhode Island, Central Massachusetts and Northeast Connecticut. The storm departed Southeast New England by 5 AM where all tropical warnings were lowered for the area. Amateur Radio SKYWARN Nets were instrumental in gathering many of these reports with non-Amateur Radio SKYWARN Spotters calling in their rainfall reports in on Saturday Morning. Amateur Radio Nets were active on the 146.955-Barnstable, 145.49-Fairhaven Repeaters with the New England Reflector IRLP/Echolink system active and lined with the *WX_TALK* Echolink Conference Node: 7203/IRLP 9219 system for the VoIP Hurricane Net. HF was active on 3943 KHz LSB with the Hurricane Watch Net active on 14.325 MHz. Other repeaters and frequencies in the region were on stand-by for Earl.
The storm would approach Nova Scotia Canada on Saturday Morning. Earl would deviate slightly from his track and the center would come closer to the heavily populated Halifax Nova Scotia Canada area. The right side of Earl’s circulation with the strongest wind fields would affect the Greater Halifax area and much of Nova Scotia into the Prince Edward Islands. Weather stations in the area reported high-end tropical storm force sustained winds with frequent hurricane force wind gusts. This resulted in widespread tree and power line damage in the Greater Halifax Nova Scotia Canada with some minor structural damage noted to roofs of homes either from fallen trees and spotty direct roof damage from the winds. Contact was made with VE1JBL-Jim Langille, Radio Amateurs of Canada Maritime Section Manager using Amateur Radio Internet linking technology and Jim was at the Halifax Emergency Operations Center reporting on the severe damage done by Earl. The Canadian Hurricane Centre and National Hurricane Center were at odds as to whether the system made landfall as a Category-1 hurricane or a high-end tropical storm. It is noted that the difference in intensity between the two characterizations, however, is minimal. During the height of the storm, 216,000 people were without power. Outages were down to 70,000 by Sunday Morning and at the writing of this report were dropped to just 3,400 people. Earl would become extratropical over Newfoundland and Labrador Canada late Saturday Evening.
While Earl spared Southern New England severe conditions, this offered up a very good exercise to practice and put into place emergency response plans should a severe hurricane strike on the region. Many good things came out of practicing and executing preparedness plans. Where we still have another 4-5 weeks for New England to potentially be stricken by a tropical system, it was good to have an oppportunity to practice beyond an exericse with a real threat from a system like Earl despite its rapid weakening in the 24-36 hours prior to his arrival to our region. We hope all people will prepare the same way next time as limits in the science particularly with the intensity of these systems are still an area of research for tropical systems regardless of whether they are in the tropics or at higher latitudes. Combine the fact that Earl tracked through the higher latitudes and it wasn’t clear when the acceleration of the system would commence caused the prediction of the intensity of Earl to become that much more problematic. The track guidance between Nantucket Island and the 40 North/70 West benchmark went as expected.
Part of the preparedness steps included the Amateur Radio HF Eastern Region Communications Test which received extremely strong participation with over 50 Amateurs checking into the test and thoroughly impressed Tim Rutkowski-KB4FNQ, the Amateur Operator for the Eletronic Systems Division who requested this test be completed. Below is a link to the Communications test results where the signal report listed by each station was the signal of how they heard Eastern Region Headquarters and Tim Rutkowski-KB4FNQ’s comments:
http://beta.wx1box.org/files/erh_comms_test_results.txt
I really appreciated the contacts, yesterday. It was the first time the
station at ERH was tested in an operational mode. I never expected the
amount of cooperation that was received from your group. The three
stations that I received the best are: KA1IOR, K1CCT and W1RV. I will be
looking into other options to improve system performance. Again, thanks
for all your help.
Tim Rutkowski, ER EPM

Hello to all…
The following is the post storm report and analysis on Hurricane Earl and his impact to the Caribbean Islands, North Carolina, Southeast New England and the Canadian Maritimes. Hurricane Earl was the second major hurricane of the 2010 Atlantic Season with the first being Danielle and Danielle was a system that only affected shipping interests out at sea.
Earl passed through the Northern Leeward Islands, Virgin Islands and Puerto Rico on Monday August 31st, 2010. The storm’s worst effects were over St. Kitts, St. Maarten, the British Virgin Islands, and Anguilla where an 88 MPH measured wind gust occurred before the wind instrument malfunctioned. Earl downed numerous trees and power lines with some minor structural damage noted. Rainfall of 7-9″ was common over this area and into Antigua where a 45 MPH measured gust was noted by an Amateur Operator on the island. Cars stuck in flood waters from the rain were reported along with storm surge issues on vulnerable portions of the islands. A 60 knot measured wind gust was recorded on the US Virgin Islands as well. Amateur Radio Operators and the stormcarib.com storm blogging network were critical in obtaining reports from this area.
Earl would traverse the open Atlantic Ocean waters northeast of the Bahamas before coming within 125 miles of the mid-atlantic coast of Eastern North Carolina where hurricane warnings were issued for Eastern North Carolina and the Outer Banks with tropical storm watches and warnings north and south of portions of Eastern North Carolina and the Outer Banks of North Carolina. During this timeframe, Hurricane and Tropical Storm Watches and Warnings would be issued over the course of Wednesday and Thursday for portions of New England. Earl was a dangerous Categrory IV hurricane at the time. The forecast was only for slow weakening and the storm to pass within 50-100 miles southeast of Nantucket Island and as a strong Category II to Category III hurricane. Given a system of that magnitude, it was expected that the system would stay fairly symmetrical and while Southern New England would be on the side of the storm with weaker winds, high sustained tropical storm force winds with hurricane force wind gusts were expected particularly in the area of the hurricane warning from Plymouth to Westport Massachusetts including Cape Cod and the Islands. Areas west and north of this region were expected to see tropical storm force winds in gusts and possibly low-end sustained tropical storm force winds.
As Earl approached North Carolina, Measured sustained winds to high-end tropical storm force with hurricane force wind gusts were recorded with storm surge in the 2-5 foot range. Rainfall was largely under 1″ except in the outer banks of North Carolina where 3.5-4.5″ rainfall amounts occurred. Earl’s eye would never make landfall in the outer banks of North Carolina and would stay offshore within 125 miles of the Outer Banks. Over the course of this time, Earl weakened considerably going from a Category-IV hurricane on Thursday Morning to a Category-I hurricane by Friday Morning due to southwest shear and dry air intrusion into the system. This was expected on Wednesday but instead the system intensified which raised concerns that Earl would affect the region as a stronger system but on Thursday these factors finally took their toll on Earl. Due to the rapid weakening, this made the storm that much more asymmetric and a much weaker system as it affected Southeast New England Friday Afternoon and particularly Friday Night and this meant the heavy rain would be along and west of the center with most of the wind along and east of the center of Earl with weaker winds to the west of the center. It is noted that non-tropical models had a better handle on the weakening wind field on the west side of the system and the asymmetry of the system. Also, while the system was moving at about 20 MPH, this is not the noted acceleration of historic New England hurricanes of the 1930s-1950s or even Hurricane Bob in 1991 and Hurricane Gloria in 1995 which moved at rates between 30 and 60 MPH. This meant more weakening due to cooler water temperatures despite those water tempratures being warmer than normal and the shear and dry air over the system also had significant impacts on Earl. Earl would weaken to a tropical storm as it made its closest approach to Southeast New England resulting in hurricane warnings being changed to tropical storm warnings over Cape Cod and the Islands late Friday Evening after the Hurricane Warnings were changed to Tropical Storm Warnings over the Hull to Plymouth area and from Woods Hole to Westport, Massachusetts late Friday Morning.
When Earl approached, winds only reached low-end tropical storm force criteria on Nantucket Island with tropical storm force winds in gusts over South Coastal Massachusetts and Cape Cod. Measured wind gusts of 42 MPH were recorded on West Island Fairhaven, 41 MPH on Marstons Mills section Barnstable, Massachusetts, 44 MPH measured gust on Marthas Vineyard and 41 MPH measured gust in the Siasconsett portion of Nantucket Island. Storm surge from swells closed some shore roads in Newport, RI, Dennis, Mass. and threatened some homes with flooded beach areas in the Madaket section of Nantucket Island. A couple of isolated 50 Knot gusts were seen at the elevated platform at Horseshoe Shoals Nantucket Island and at the Kalmas weather station in Barnstable, Mass. via weatherflow with a 54 MPH gust measured at Nantucket Airport along with a sustained wind of 41 MPH. The winds downed isolated trees and caused isolated power outages in Chatham, Dennis, and on the Bourne/Falmouth line.
The bigger story was heavy rainfall with 2-4″ with isolated 6″ amounts occurring from West Island Fairhaven through Barnstable County, Martha’s Vineyard and Nantucket Islands. This resulted in urban flooding over portions of Cape Cod shutting down a few roads and intersections. The combination of storm surge and rainfall causing minor street flooding issues on Nantucket Island. Several flooded basements were reported on Martha’s Vineyard Island in Edgartown and portions of Cape Cod. Rainfall in the Greater New Bedford area west of Fairhaven through South Coastal Rhode Island and up through Taunton were between 1-2″ of rain with amounts 1″ or less over the remainder of Eastern Massachusetts, North-Central Rhode Island, Central Massachusetts and Northeast Connecticut. The storm departed Southeast New England by 5 AM where all tropical warnings were lowered for the area. Amateur Radio SKYWARN Nets were instrumental in gathering many of these reports with non-Amateur Radio SKYWARN Spotters calling in their rainfall reports in on Saturday Morning. Amateur Radio Nets were active on the 146.955-Barnstable, 145.49-Fairhaven Repeaters with the New England Reflector IRLP/Echolink system active and lined with the *WX_TALK* Echolink Conference Node: 7203/IRLP 9219 system for the VoIP Hurricane Net. HF was active on 3943 KHz LSB with the Hurricane Watch Net active on 14.325 MHz. Other repeaters and frequencies in the region were on stand-by for Earl.
The storm would approach Nova Scotia Canada on Saturday Morning. Earl would deviate slightly from his track and the center would come closer to the heavily populated Halifax Nova Scotia Canada area. The right side of Earl’s circulation with the strongest wind fields would affect the Greater Halifax area and much of Nova Scotia into the Prince Edward Islands. Weather stations in the area reported high-end tropical storm force sustained winds with frequent hurricane force wind gusts. This resulted in widespread tree and power line damage in the Greater Halifax Nova Scotia Canada with some minor structural damage noted to roofs of homes either from fallen trees and spotty direct roof damage from the winds. Contact was made with VE1JBL-Jim Langille, Radio Amateurs of Canada Maritime Section Manager using Amateur Radio Internet linking technology and Jim was at the Halifax Emergency Operations Center reporting on the severe damage done by Earl. The Canadian Hurricane Centre and National Hurricane Center were at odds as to whether the system made landfall as a Category-1 hurricane or a high-end tropical storm. It is noted that the difference in intensity between the two characterizations, however, is minimal. During the height of the storm, 216,000 people were without power. Outages were down to 70,000 by Sunday Morning and at the writing of this report were dropped to just 3,400 people. Earl would become extratropical over Newfoundland and Labrador Canada late Saturday Evening.
While Earl spared Southern New England severe conditions, this offered up a very good exercise to practice and put into place emergency response plans should a severe hurricane strike on the region. Many good things came out of practicing and executing preparedness plans. Where we still have another 4-5 weeks for New England to potentially be stricken by a tropical system, it was good to have an oppportunity to practice beyond an exericse with a real threat from a system like Earl despite its rapid weakening in the 24-36 hours prior to his arrival to our region. We hope all people will prepare the same way next time as limits in the science particularly with the intensity of these systems are still an area of research for tropical systems regardless of whether they are in the tropics or at higher latitudes. Combine the fact that Earl tracked through the higher latitudes and it wasn’t clear when the acceleration of the system would commence caused the prediction of the intensity of Earl to become that much more problematic. The track guidance between Nantucket Island and the 40 North/70 West benchmark went as expected.
Part of the preparedness steps included the Amateur Radio HF Eastern Region Communications Test which received extremely strong participation with over 50 Amateurs checking into the test and thoroughly impressed Tim Rutkowski-KB4FNQ, the Amateur Operator for the Eletronic Systems Division who requested this test be completed. Below is a link to the Communications test results where the signal report listed by each station was the signal of how they heard Eastern Region Headquarters and Tim Rutkowski-KB4FNQ’s comments:
http://beta.wx1box.org/files/erh_comms_test_results.txt
I really appreciated the contacts, yesterday. It was the first time the
station at ERH was tested in an operational mode. I never expected the
amount of cooperation that was received from your group. The three
stations that I received the best are: KA1IOR, K1CCT and W1RV. I will be
looking into other options to improve system performance. Again, thanks
for all your help.
Tim Rutkowski, ER EPM
