Hurricane Earl Coordination Message #7

Hello to all…

..Major Hurricane Earl Track Shifted a Bit Westward in 5 AM Advisory package. Hurricane Watches expanded from Plymouth Westport, Massachusetts. Inland Tropical Storm Watches issued for Bristol and Plymouth Counties..
..Major Hurricane Earl Threatens Southern New England with the potential for sustained tropical storm force winds particularly in Southeast New England but much of Eastern New England could be affected with tropical storm force winds in gusts and the potential for a period of hurricane force winds particularly over portions of Cape Cod and Nantucket Island. A further westward trend could bring hurricane force conditions as far north as Plymouth and and as far west as Westport, Massachusetts..
..A Hurricane Watch is in effect from Plymouth to Westport Massachusetts including Nantucket and Martha’s Vineyard Islands..
..A Tropical Storm Watch is in effect from the Mouth of the Merrimack River Massachusetts to Plymouth Massachusetts and from Sandy Hook New Jersey to Woods Hole Massachusetts..
..Track guidance is gradually coalesing between the 40 North/70 West benchmark and Buzzards Bay Massachusetts. Deviations in the forecast track could mean greater or lesser impact to Southern New England and there is still is up to 100-125 nautical mile error in the forecast track at this stage. Southern New England is now in the ‘3-day cone’ regarding Earl’s eventual track..
..All Emergency Management and Public Safety personnel, Amateur Radio and Non-Amateur Radio SKYWARN Spotters should continue to keep high situational awareness regarding the track and intensity of major Hurricane Earl. People should review hurricane/tropical storm safety tips now as a precaution..
..VoIP Hurricane Net and Hurricane Watch Net along with WX4NHC, Amateur Radio Station at the National Hurricane Center will activate at 4 PM Thursday Afternoon for Earl’s closest path to the Outer Banks and Eastern North Carolina, Eastern Virginia and the Delmarva Peninsula..
..SKYWARN Activation with Ops at NWS Taunton are likely Friday Morning into Saturday Morning based on the current track and intensity of Hurricane Earl. Massachusetts State EOC RACES and MEMA RACES Regional Office activation is slated to occur Friday Morning. Eastern Massachusetts ARES will be placed on stand-by starting at 7 AM ET Friday Morning lasting through 7 PM Saturday Evening..

Models are gradually coalesing on a solution putting Earl anywhere from around the 40 North/70 West Benchmark and then east of Cape Cod to a track over Cape Cod and between Martha’s Vineyard and Nantucket Islands. There remain some eastward and westward outliers but the general consensus of models is between those two areas. There remains a 100-125 nautical mile error which can still result in greater or lesser impact over the region. A continued westward trend has been noted with computer models with tracks anywhere from Buzzards Bay to the 40 North/70 West benchmark. This needs to be closely monitored for a more westward trend and greater impact to the region. It has resulted in an expansion of Hurricane Watches and they now cover from Plymouth to Westport, Massachusetts. 

The following is a rough estimation of impacts over the Tropical Storm and Hurricane Watch areas based on the current track and intensity of the hurricane and its extremely large size. This could change based on hurricane intensity and track of the system:

Hurricane Watch Area (Sagamore Beach to Woods Hole Cape Cod, Martha’s Vinyeard and Nantucket Islands):

This region will see high-end sustained tropical storm force winds with hurricane force wind gusts. It is now looking more likely that the Outer Cape and particularly Nantucket Island would have the potential to also see sustained hurricane force winds and gusts pending the eventual track of Earl. Rainfall will be very heavy with the potential for a swath of 3-6″ rainfall with isolated higher amounts. Storm surge will be most prevelant over north and east facing beaches with a 1-3 foot surge affected. Locations in Provincetown and Wellfleet could see greater impact if the track is a bit closer and the storm surge may occur some time after storm passage depending on that track.

Hurricane Watch Area (Plymouth to Sagamore Beach and from Westport Massachusetts to Sagamore Beach Massachusetts)

This area could see sustained winds of 35-45 MPH with gusts to 60-70 MPH and possibly slightly higher gusts. The Hurricane Watch has been issued to guard against a more westward solution towards Buzzards Bay. If that were to verify, hurricane force conditions sustained or in gusts may occur but the current solution would keep most of that to the east of this region. Rainfall in this area is likely to be 3-6″ with isolated higher amounts along the coast and inland Southern Bristol and Southern Plymouth Counties of Massachusetts. Storm surge over the south coast isn’t expected to be a major factor due to the wind direction but a 1-2 foot surge could occur over the Plymouth area depending on the track of Earl.

Tropical Storm Watch Area (Mouth of Merrimack River Massachusetts to Plymouth Massachusetts and South Coastal Rhode Island including the Tropical Storm Inland Wind Watch for Northern Bristol and North-Central Plymouth Counties):

In this area, sustained winds of 20-30 MPH with gusts of 40-50 MPH are possible depending on the track of Earl with the exception of inland Bristol and Plymouth Counties which could see sustained winds of 30-40 MPH with gusts to 60-65 MPH. Across the remainder of Rhode Island and Eastern Massachusetts inland of the TS Watch winds will drop off a bit with rainfall of 2-4″ with isolated higher amounts possible but if a further west track were to materialize more wind could occur in portions of Rhode Island and Eastern Massachusetts. It is noted that portions of Worcester County and Northeast Connecticut could see 1-3″ of rainfall.

There remains 3 factors that will further determine the track of Major Hurricane Earl that are still being scrutinized by the weather models are as follows:

1.) The strength and location of the Great Lakes trough and its interaction with Hurricane Earl
The strength and location of the Great Lakes trough and its interaction with Hurricane Earl will be critical. If the trough’s location is further west or not amplifying and interacting with Hurricane Earl, this would allow a closer to the coast track and more direct impact. If it amplifies and can interact with Earl, it would result in a greater push to the east.

2.) The sharpness and locations of the turns Earl will make
Depending on the sharpness and locations of Earl turns will determine the interaction with the Great Lakes trough and his eventual movement. This will be especially true as Earl approaches the Outer Banks of North Carolina on Thursday and this will be a critical time in the track and impact of Hurricane Earl on Southern New England.

3.) Intensity of Hurricane Earl as it moves up the coast
The intensity of Hurricane Earl will now be controlled by eyewall replacement cycles and other shorter-term phenomenon that cannot be fully predicted. Earl has gone through a significant intensification process and has grown in size. Unlike past hurricanes that have been much weaker as they approached New England, water temperatures are above normal and Earl is a very powerful and large hurricane. This is likely to result in greater impact from Earl then most tropical systems approaching New England because of its large size and intensity. In addition, the intensity of Earl may affect the movement of the system.

Swells and rip currents will become a very serious concern as Earl tracks closer to the region on Thursday extending through the Labor Day Holiday Weekend after Earl passes. There have been many times where offshore tropical systems have caused injuries or fatalities on the water from the surf and rip currents so folks swimming at area beaches over the next several days with the hot weather expected are advise to heed the advice of lifeguards and monitor NWS Taunton products for high surf advisory information. See link below for the the surf zone forecasts for more information and if High Surf Advisories are posted, that link will be posted and updated here:

All Emergency Management and Public Safety personnel, Amateur Radio and Non-Amateur Radio SKYWARN Spotters should continue to keep high situational awareness regarding the track and intensity of major Hurricane Earl. People should now be reviewing their preparedness measures for tropical storm/hurricane force conditions as a precaution in inland areas and as a requirement along the coast in the Tropical Storm and Hurricane Watch areas. This information has been provided via the Hurricane Preparedness Week Public Information Statements of Safety Tips and an updated Public Information Statement of Safety Tips as well as a Tropical Terminology Public Information Statement listed via the links below:

The VoIP Hurricane Net and Hurricane Watch Net along with WX4NHC, Amateur Radio Station at the National Hurricane Center will activate at 4 PM Thursday Afternoon for Earl’s closest path to the Outer Banks and Eastern North Carolina, Eastern Virginia and the Delmarva Peninsula. These nets will likely activate again Friday for Earl’s closest path to New England. It is noted that the VoIP Hurricane Net will merge into one large command net with New England Echolink/IRLP operations as it approaches New England.

From a spotting perspective, we will be looking for any and all reports per the SKYWARN reporting criteria. We’ll also be looking for lowest barometric pressure readings across Southeast New England. Also, pictures of damage and incidents as they occur in near real-time or shortly after release will be very helpful to media, emergency manamgement, the National Hurricane Center and the NWS Taunton Forecast Office.
