Track of Irene

Although these images show Irene (09L) a few days ago while it was at hurricane strength, the system has since been downgraded to a tropical storm. Its center is currently nearing northern New England, USA, about 65 miles (100km) south of Rutland, Vermont.

This motion with a little faster forward speed is expected over the next
day or so. On the forecast track, the center of Irene will move over eastern Canada tonight and early Monday.

Maximum sustained winds have decreased to about 50 mph (85 km/h), with present movement towards the north-northeast (or 20 degrees) at 26 mph (43kph). Minimum central pressure is 975 mb (28.79 in).

A tropical storm warning is in effect for Cape Henlopen, Delaware northward to Eastport, Maine, including Delaware Bay, New York City, Long Island, Long Island Sound, coastal Connecticut and Rhode Island, Block Island, Marthas Vineyard and Nantucket. This warning also applies to the United States/Canada border northeastward to Fort Lawrence, including Grand Manan, and the south coast of Nova Scotia from Fort Lawrence to Porters Lake. Interests elsewhere in eastern Canada should monitor the progress of
Irene.

Hazards affecting land include storm surge, rainfall and wind. Elevated water levels will persist in areas of onshore winds along the coast from Connecticut through Maine. The highest water levels will occur near the upper parts of bays and inlets. Near the coast, these elevated water levels will also be accompanied by large, destructive and life-threatening waves. Higher than normal astronomical tides are occurring this weekend. Coastal and river flooding will be highest around the time of high tide.

Irene is expected to produce total rainfall accumulations of 4 to 6 inches, with isolated maximum amounts of 8 inches, from northeastern New York State northeastward through the northern portion of New England. These rains, combined with heavy rains over the past few weeks, could cause widespread flooding and life-threatening flash floods.

Tropical storm force winds will spread northward into portions of New Brunswick and Nova Scotia later today. Significantly higher wind speeds are likely over areas of elevated terrain in northern New England and eastern Canada.
