Hurricane Irene Coordination Message #1

Hello to all..

..Hurricane Irene is expected to intensify into a Category 3 hurricane and lash the Turks and Caicos Islands and Bahamas over the next couple days. Its current expected track will then be to impact the Carolina Coast tracking to a position over the Outer Banks of North Carolina with potential impact to New England in the Sunday to Monday timeframe..
..Multiple Models are in agreement on a potential impact to Southern New England in the Sunday to Monday timeframe but we are still 5 or more days out and things could change. All of Southern New England is in the ‘cone of uncertainity track error’ for the extended period. The extent on specifics of impact are too early to state at this time but Heavy Rain, Gusty Winds, and Coastal Flooding and Beach Erosion along the South Coast of New England are potential threats..
..VoIP Hurricane Net and Hurricane Watch Net are both active monitoring conditions in the Bahamas and Turks and Caicos Islands. They will likely be active Wednesday and Thursday..
..Interests in Southern New England should begin monitoring the progress of Hurricane Irene. This message’s intent, at this very early stage, is to have folks begin the monitoring process..

Hurricane Irene has been lashing the Turks and Caicos Islands with tropical storm to hurricane force conditions throughout much of the day and this will spread into much of the Bahamas over the next couple days. The current NHC track brings the system through the Bahamas and then up to the Outer Banks of North Carolina. Outward to 5 days, Irene is expected to move towards our region of New England. Models are in very good agreement, however, we are still about 5 or more days out and much could change. There are track errors of up to 250 miles over this period that could still occur. The track error ‘cone of uncertainty’ is now reaching all of Southern New England with the latest forecast package. It is difficult to get into any specific impacts but Heavy Rains, Gusty Winds, and Coastal Flooding to South Coastal New England are all potential threats.

The VoIP Hurricane Net and Hurricane Watch Net have been active over the past couple days for Irene’s impact on Puerto Rico, Dominican Republic, the Turks and Caicos Islands and the Bahamas. See their respective net links for details:

VoIP Hurricane Net:
http://www.voipwx.net

Hurricane Watch Net:
http://www.hwn.org

High Surf conditions will begin to affect the New England coast in a few days. Swells and Rip Currents can be very dangerous to both the experienced and inexperienced swimmer. High Surf Advisory Statements will likely be issued later this week and also the surf zone forecasts will provide more information. See links below:

Amateur Radio and Non-Amateur Radio SKYWARN Spotters should continue to keep high situational awareness regarding the track and intensity of Hurricane Irene. People should gradually begin reviewing their preparedness measures for tropical storm/hurricane force conditions as a precaution. This information has been provided via the Hurricane Preparedness Week Public Information Statements of Safety Tips via the link below:

Severe Weather Coordination Message #1 – Sunday August 21st 2011 Severe Weather Threat

Hello to all..

..Isolated to Scattered Strong to Severe Thunderstorms are likely Sunday with the potential for a more widespread severe weather event for interior sections of Southern New England for Sunday Afternoon and Evening. Damaging Winds, Large Hail and Urban/Poor Drainage flooding are the primary threats..
..Storm Prediction Center and NWS Taunton are in agreement on a Slight Risk for Severe Weather Sunday Afternoon and Evening particularly over Southern New Hampshire, Western and Central Massachusetts and Connecticut but all areas should montior the situation. Timeframe looks to be towards mid to late Sunday afternoon and evening but could start as early as 1 PM..
..SKYWARN Activation with Ops at NWS Taunton are likely Sunday Afternoon and Evening..

Sunday has the potential to be an active severe weather day in portions of interior Southern New England. While Southern New Hampshire, Western and Central Massachusetts and Connecticut are the highest areas of concern, areas to the east could also be affected depending on the timing of a very strong cold front sweeping through the area and the degree of destablization over the region.

Weather models are indicating more instability than previous runs concerning a potential severe weather event for Sunday. The key here will be the amount of sunshine through the day tomorrow and the amount of destablization. Wind shear profiles, as they have been on several events this summer, look very strong and favorable for severe weather. Cooling aloft is expected to occur similar in magnitude to Friday’s severe weather event but different from Friday’s severe weather event is the stronger winds aloft that are expected Sunday. Presuming enough heating and destablization can occur, this could lead to Isolated to Scattered Strong to Severe Thunderstorms or potential squall line formation over the region with damaging winds, large hail and urban/poor draiange flooding as the main threats. If there are more clouds and less destablization, the severe weather could be more isolated to scattered but with the amount of shear and cooling aloft presenting a low instability/high shear environment, there is still likely to be a few isolated to scattered strong to severe thunderstorms in this scenario as well.

SKYWARN Activation with Ops at NWS Taunton are likely Sunday Afternoon and Evening. Ops could start as early as 1 PM or as late as 3-4 PM. This will be adjusted Sunday Morning prior to the next coordination message which will be sent by 1130 AM Sunday. Below are the NWS Taunton Hazardous Weather Oulook and SPC Day-2 Convective Outlook:

NWS Taunton Public Information Statement – 20th Anniversary of Hurricane Bob

Hello to all..

The last hurricane to make a direct hit on Southern New England was Hurricane Bob on August 19th, 1991 and Friday marked the 20th Anniversary of Hurricane Bob’s landfall in the region. Hurricane Bob caused extensive damage in Southern New England from hurricane force winds and storm surge as well as from heavy rainfall and flooding. While it has been 20 years since the last hurricane to directly impact Southern New England as a hurricane, tropical systems have made their mark on New England during this period with tropical storm conditions and in some cases hurricane force wind gusts to parts of the region such as what occurred with Hurricane Edouard over Cape Cod and the Islands in September 1996 and Tropical Storm Bertha over much of the Southern New England coast in July 1996. Other tropical storms that had some impact on the region with heavy rainfall and tropical storm force winds included Tropical Storm Hannah in September 2008, Hurricane Floyd, which affected the region as a tropical storm in September 1999 and Tropical Storm Danny in July 1997. There have also been remnants of tropical systems over the years that have brought flooding and severe weather to the region.

While it has been 20 years since the last direct impact by a hurricane to Southern New England, we are approaching the peak of hurricane season. Now is the time to prepare for the new season. Even if a hurricane does not strike the region, you will be more prepared for any other weather related disaster scenarios that could occur during the winter or other timeframes.

To commemorate Hurricane Bob’s landfall on Southern New England, NWS Taunton issued a Public Information Statement concerning Hurricane Bob highlighting some of his impacts and that despite Bob’s significant hit to the area, he was not a major hurricane and the last major hurricane strike was Hurricane Carol in 1954. Below is the Public Information Statement commemorating the 20th anniversary of Hurricane Bob:

PUBLIC INFORMATION STATEMENT
NATIONAL WEATHER SERVICE TAUNTON MA
1112 AM EDT FRI AUG 19 2011

…20 YEARS SINCE HURRICANE BOB HIT NEW ENGLAND…

THE LAST TIME THAT NEW ENGLAND TOOK A DIRECT HIT FROM A HURRICANE
WAS 20 YEARS AGO…ON AUGUST 19 1991…WHEN HURRICANE BOB HIT
SOUTHEASTERN NEW ENGLAND. AS BAD AS BOB WAS…IT WAS ONLY A CATEGORY
TWO HURRICANE AT LANDFALL. THE LAST TIME THAT NEW ENGLAND WAS HIT BY
A MAJOR HURRICANE…CATEGORY 3…WAS IN 1954 WHICH IS 57 YEARS AGO.

HURRICANE BOB DEVELOPED IN THE CENTRAL BAHAMAS ON AUGUST 16
1991…THEN STEADILY INTENSIFIED AND REACHED HURRICANE STATUS ON
THE EVENING OF AUGUST 17. BOB STRENGTHENED AND ACCELERATED
NORTHEASTWARD. THE EYE OF BOB PASSED OVER BLOCK ISLAND, RI AT
APPROXIMATELY 130 PM ON AUGUST 19 AND MADE LANDFALL OVER
NEWPORT, RI SHORTLY BEFORE 2 PM.

HURRICANE BOB BROUGHT SUSTAINED HURRICANE FORCE WINDS TO THE
IMMEDIATE COASTAL COMMUNITIES OF RHODE ISLAND AND MOST OF
SOUTHEASTERN MASSACHUSETTS. STRONG TROPICAL STORM FORCE WINDS BLEW
ACROSS THE REMAINDER OF THE REGION WITH MANY AREAS RECEIVING GUSTS
TO HURRICANE FORCE EAST OF THE CONNECTICUT RIVER. WIND DAMAGE TO
TREES AND UTILITY POLES WAS COMMON AND RESULTED 60 PERCENT OF
RESIDENTS IN SOUTHEAST RHODE ISLAND AND SOUTHEAST MASSACHUSETTS
LOSING POWER. APPLE AND PEACH ORCHARDS THERE WERE EXTENSIVELY
DAMAGED.

COASTAL COMMUNITIES BORE THE BRUNT OF THE STORM WITH SUSTAINED WINDS
BETWEEN 75 AND 100 MPH. GUSTS TO 125 MPH WERE RECORDED IN BREWSTER
AND NORTH TRURO ON CAPE COD…AND ALSO IN WETHERSFIELD CONNECTICUT.
THE HIGHEST SUSTAINED WIND…OF 100 MPH…WAS RECORDED IN NORTH
TRURO. BLOCK ISLAND REPORTED SUSTAINED WINDS OF 90 MPH WITH GUSTS IN
EXCESS OF 105 MPH WHICH WAS THE MAXIMUM SPEED OF THAT EQUIPMENT.
THERE WERE 4 REPORTS OF TORNADOES AS BOB CAME ASHORE. THE LOWEST
BAROMETRIC PRESSURE WAS RECORDED BY THE USS VALDEZ WHILE IN THE EAST
PASSAGE OF NARRAGANSETT BAY…WITH A READING OF 28.47. 

HURRICANE BOB CAUSED A STORM SURGE OF 5 TO 8 FEET ALONG THE RHODE
ISLAND SHORE…BUT DROVE A SURGE OF 10 TO 15 FEET INTO BUZZARDS BAY.
THE HIGHEST SURGES…12 TO 15 FEET…WERE OBSERVED IN ONSET…
BOURNE…MASHPEE…AND WAREHAM AT THE HEAD OF BUZZARDS BAY.
COVE ROAD…IN MATTAPOISETT MASSACHUSETTS…HAD 29 OF 37 HOMES
DESTROYED WHILE ANGELICA POINT MASSACHUSETTS LOST 32 OF 35 HOMES
ALONG THE SHORE. BOAT DAMAGE WAS SIGNIFICANT WITH MANY BOATS TORN
FROM THEIR MOORINGS. SOME SOUTH FACING BEACHES ON MARTHAS VINEYARD
AND NANTUCKET LOST UP TO 50 FEET OF BEACH DUE TO EROSION.

AS IS TYPICALLY THE CASE WITH NEW ENGLAND HURRICANES…HEAVY RAIN
WAS FOCUSED TO THE WEST OF THE TRACK OF THE STORM. 3 TO 7 INCHES OF
RAIN OCCURRED ACROSS ALL OF RHODE ISLAND EXCEPT THE SOUTHEAST
PORTION…WITH THE HIGHEST READING OF 7.01 INCHES IN FOSTER. LESS
THAN AN INCH OF RAIN OCCURRED ON CAPE COD TO THE EAST OF THE
TRACK…BUT THAT IS WHERE THE HIGHEST WINDS AND STORM SURGE OCCURRED.

BOB WAS RESPONSIBLE FOR SIX DEATHS IN THE REGION…ALL IN
CONNECTICUT. TOTAL DAMAGE IN SOUTHERN NEW ENGLAND WAS APPROXIMATELY
680 MILLION DOLLARS.

THIS INFORMATION WAS TAKEN FROM A PAPER ENTITLED “SOUTHERN NEW
ENGLAND TROPICAL STORMS AND HURRICANES, A NINETY-EIGHT YEAR SUMMARY
1909-1997″ BY DAVID R. VALLEE AND MICHAEL R. DION, NATIONAL WEATHER
SERVICE – TAUNTON, MA.

Severe Weather Coordination Message #2 – Friday August 19th 2011 Severe Weather Threat

Hello to all..

..Isolated to Scattered Strong to Severe Thunderstorms possible this afternoon and evening across much of the NWS Taunton County Warning Area, particularly interior areas. Damaging Winds, Large Hail and urban/poor drainage flooding are the main threats..
..Threat will be in the form of strong thunderstorms to isolated pulse type severe thunderstorms over the region due to lack of strong winds in the upper levels of the atmosphere..
..SKYWARN Activation with Ops at NWS Taunton are possible to likely this afternoon and evening..

At 715 AM, satellite imagery showed mostly clear conditions with some patchy clouds that should burn off over parts of the region later this afternoon. This should allow for strong heating and destablization over the region. In addition, a cold pool of temperatures aloft should also support more destablization over the region. A mitigating factor for today will be the lack of strong winds in the upper levels of the atmosphere. Putting this all together, there will be isolated to scattered strong thunderstorms with a few isolated pulse type severe thunderstorms over the region with damaging winds, large hail and urban and poor drainage flooding as the main threats.

SKYWARN Activation with Ops at NWS Taunton are possible to likely this afternoon and evening. This will be the last complete coordination message on this threat. A shortened coordination message will be issued if time allows and Ops at NWS Taunton are initiated. Below is the NWS Taunton Hazardous Weather Outlook:

Severe Weather Coordination Message #1 – Friday August 19th, 2011 Severe Weather Threat

Hello to all..

..Isolated to Scattered Strong to Severe Thunderstorms are possible Friday Afternoon into the early evening across much of the NWS Taunton County Warning Area. Damaging winds, large hail and urban/poor drainage flooding are the main threats..
..Weak wind fields aloft should preclude a significant severe weather outbreak but cooler temperatures aloft combined with daytime heating may allow pulse type isolated severe thunderstorms along with strong thunderstorms to form over the area and be a bit more widespread than today when an isolated strong thunderstorm over Ashburnham Massachusetts dumped 1.5″ of rain in 30 minutes and produced pea sized hail..
..SKYWARN Activation with Ops at NWS Taunton are possible Friday Afternoon into early evening. A more complete coordination message will be posted by 830 AM Friday Morning. Below is the NWS Taunton Hazardous Weather Outlook..

Storm Coordination Message #1 – Monday August 15th, 2011 Storm/Rainfall Event

Hello to all..

..Strong Storm System will bring another round of Heavy Rainfall to Southern New England, particularly in portions of Western New England..
..A Flood Watch is in effect from Midnight Tonight through Monday Evening for Western Hampshire, Western Hampden and Western Hampden Counties of Massachusetts. Areas outside of the flood watch area particularly in the remainder of Western and Central Massachusetts and Northern Connecticut would have the potential for urban/poor drainage flooding depending on the axis of heavy rainfall..
..SKYWARN Self-Activation will be utilized for rainfall reports meeting SKYWARN Reporting criteria and any flooding. Ops at NWS Taunton may be utilized if the threat for flooding becomes more widespread..

At 430 PM, Doppler Radar has shown rainfall over Connecticut and extending into portions of Western and Central Massachusetts and Western Rhode Island. Heavier Rainfall has occurred over the New York City and Long Island area into New Jersey. Some locations received almost 8″ of rainfall in Nassau County New York.

Rainfall of the magnitude over Long Island New York is not expected in the NWS Taunton County Warning Area, however, widespread 1-3″ rainfall is expected over much of the NWS Taunton County Warning Area especially in Southwest New Hampshire, Western and Central Massachusetts and Connecticut with amounts of 2-4″ of Rain expected over Western Franklin, Western Hampshire and Western Franklin Counties where a Flood Watch is in effect from Midnight tonight through Monday Evening. In the flood watch area, urban/poor drainage flooding and river/stream flooding are the main threats. Areas just outside of the flood watch particularly in Western and Central Massachusetts and Connecticut may see urban/poor drainage flooding but less likely to see river and stream flooding. Urban areas of Eastern Massachusetts and Rhode Island may also have urban/poor drianage flooding depending on the amount of rainfall and the timeframe with which the rainfall falls.

SKYWARN Self-Activation to monitor for rainfall reports meeting SKYWARN reportable crtieria and any flooding is the most likely way for this storm to be handled. Ops at NWS Taunton are possible if the threat for flooding is more widespread. This will be the only coordination message on this event unless the threat for flooding increases. If the threat increases, another coordination message will be issued Monday Morning. Below is the NWS Taunton Flood Watch Statement and Hazardous Weather Outlook:

Severe Weather Coordination Message #2 – Wednesday August 10th, 2011 Severe Weather Threat

Hello to all..

..Isolated to Scattered Strong to Severe Thunderstorms are possible across much of the NWS Taunton County Warning Area for Wednesday Afternoon and Evening with a secondary cold front and cooler air aloft as the atmosphere destabilizes later this morning into the afternoon over much of the region. Damaging Winds, Large Hail and urban/poor drainage flooding are the primary threats..
..Threat timeframe still appears to be after 4 PM, however, radar trends will need to be monitored in case the threat is a bit earlier than expected due to activity in Central New York currently moving slowly eastward..
..SKYWARN Activation with Ops at NWS Taunton are possible to likely later this afternoon and this evening..

Overnight, heavy rainfall affected portions of Northwest Connecticut, Central and Northeast Massachusetts and Southeast New Hampshire with widespread 1-3″ rainfall with slightly higher amounts over this area. This may have resulted in urban flooding during the overnight hours.

Satellite imagery shows clearing moving in over Western Massachusetts, Connecticut, parts of Rhode Island and Southeast Massachusetts with mostly clear conditions over Eastern New York State. This clearing should move into Central Massachusetts and the remainder of Eastern Massachusetts later this morning. Doppler Radar is showing some scattered heavy shower and possible isolated thunderstorm activity over Central New York just east of the Finger Lakes moving slowly eastward. This activity will need to be monitored to see if it organizes and picks up speed as wind shear profiles increase over the area.

Isolated to scattered strong to severe thunderstorms are possible for much of the NWS Taunton County Warning Area as we get into later this afternoon and evening. Cooling aloft and sufficient wind shear profiles with likely heating and destablization given current satellite imagery showing clearing moving in the area are supporting factors to isolated to scattered strong to severe thunderstorm activity. A possible limiting factor will be drying and a drop of the dewpoints. That situation occurred last Tuesday August 2nd and limited the severe weather potential though isolated to scattered strong to severe thunderstorms did occur on that day over Eastern Massachusetts. Threat timeframe looks to be after 4 PM today though an earlier start time will need to be monitored depending on the activity in Central New York State east of the Finger Lakes.

SKYWARN Activation with Ops at NWS Taunton are possible to likely today. This will be the last complete coordination message on this threat. A shortened coordination message will be issued if time allows and Ops at NWS Taunton are initiated. Below are the NWS Taunton Hazardous Weather Outlook and SPC Day-1 Convective Outlook:
