Hurricane Irene formed east of the Caribbean island of Dominica, part of the Lesser Antilles region, on the afternoon of August 20. Irene moved through the Caribbean and up the east coast of the United States making landfall twice. She first made landfall as a Category 1 Hurricane near Cape Lookout, North Carolina around 7:30am on August 27, then moved offshore again during the evening. She then made a 2nd landfall, again as a Category 1 Hurricane at 540am on August 28 near Little Egg Inlet in New Jersey. She moved over New York City and then into southeastern New York State and Connecticut as a Tropical Storm a few hours later. By the end of the evening of the 28th, Irene was crossing the U.S./Canada border having produced significant amounts of rain, storm surge, inland and coastal flooding, and wind damage across southern New England and much of the east coast of the United States.
In Southern New England, the minimum surface pressure recorded was 976.9mb taken at Barnes Municipal Airport in Westfield, Massachusetts. The storm surge experienced along the coast was generally in the two to four foot range with a high of 4.78 feet at Fox Point in Providence, Rhode Island. The highest sustained windspeed was 54 knots (62 mph) at the Physical Oceanographic Real Time System station at Conimicut Light in Narragansett Bay, RI. The highest sustained wind speed on land was 38 knots (44 mph) recorded on the Automated Surface Observing Systems at both Barnstable Municipal Airport in Hyannis, MA (KHYA) and Logan International Airport in Boston, MA (KBOS). Rainfall amounts ranged from nearly zero (0.03 at Nantucket Memorial Airport - ACK) to nearly 10 inches (9.92 in Conway, MA).
Despite the relatively low wind speeds, sustained winds over a 6 to 12 hour long duration resulted in widespread tree damage and resulted in power outages to roughly half a million customers throughout the state. Some of these customers did not get their power back until the Friday following the storm (some five days later). Durring the passage of Tropical Storm Irene, the winds resulted in $25,000 in property damages.
The Connecticut River at Walpole reached its highest level since the 1938 hurricane.
The collective effects of Tropical Storm Irene on August 28, resulted in 1 fatality, 0 injuries, and $127.3M in property damage in the following counties: Barnstable, Bristol, Essex, Franklin, Hampden, Hampshire, Middlesex, Nantucket, Norfolk, Plymouth, Suffolk, and Worcester (all in MA), Hartford, Tolland, and Windham (all in CT), Cheshire and Hillsborough (all in NH), and Bristol, Providence, Kent, Washington, and Newport (all in RI).
