Hurricane Irene (09L) - August 27th, 2011

Enhanced image

Hurricane Irene (09L) left extensive flood and wind damage along its path through the Caribbean, the east coast of the USA and as far north as Canada.

These images show the system on August 27, as it was approaching the Outer Banks of North Carolina and had weakened to a Category 1 hurricane. At 7:30 am EDT (11:30 UTC) the same day, Irene made landfall near Cape Lookout, on North Carolina’s Outer Banks, with winds of 85 mph (140 km/h).

After having tracked over land for about 10 hours, the eye of Irene became cloud-filled, although the center remained well-defined on radar images. Later on August 27, Irene re-emerged into the Atlantic near the southern end of the Chesapeake Bay in Virginia.

Shortly before sunrise, at about 09:35 UTC on August 28, Irene made a second landfall at the Little Egg Inlet on the New Jersey shore,[32] and soon after moved over water again. Hours later, Irene weakened to a tropical storm just as it made a third U.S. landfall in the Coney Island area of Brooklyn, in New York City, New York, about 9:00 am EDT (13:00 UTC) on August 28.[citation needed]

Following its August 28 New York landfall, Irene moved northeast over New England, becoming post-tropical over the state of Maine at 11:00 pm EDT (03:00 UTC August 29).  The extratropical cyclone continued northward into eastern Quebec, Canada, then crossed the St. Lawrence River into Labrador before emerging into the Labrador Sea, late on August 29.

Track of Irene

Hurricane Irene (09L) was a large and powerful Atlantic hurricane that left extensive flood and wind damage along its path through the Caribbean, the United States East Coast and as far north as Atlantic Canada.

Irene tracked just north of Hispaniola as an intensifying Category 1 hurricane, skirting the coast with heavy precipitation and strong winds that killed several people.

After crossing the Turks and Caicos Islands, the hurricane quickly strengthened into a Category 3 major hurricane while passing through The Bahamas, leaving behind a trail of extensive structural damage in its wake.

Curving toward the north, Irene skirted past Florida with its outer bands producing tropical-storm-force winds. It made landfall over Eastern North Carolina’s Outer Banks on the morning of August 27 and moved along southeastern Virginia affecting the Hampton Roads region.

After briefly reemerging over water, Irene made second US landfall near Little Egg Inlet in New Jersey during the morning of August 28, becoming the first hurricane to make landfall in the state since 1903. Irene was downgraded to a tropical storm as it made its third U.S. landfall in the Coney Island area of Brooklyn, New York, at approximately 9:00 a.m on August 28.

The most extensive damage within the United States occurred in the Catskill Mountains of New York State and in Vermont, which suffered disastrous flash floods. Throughout its path, Irene caused widespread destruction and at least 44 deaths; monetary losses to the Caribbean could be as high as US$3.1 billion according to preliminary estimates. Early damage estimates in the US are about $7 billion.

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

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.

Look Back at Hurricane Irene (09L) Making Landfall Over Puerto Rico

Hurricane Irene (09L) - August 22nd, 2011

Enhanced image

Hurricane Irene (09L) is an active North Atlantic tropical cyclone that currently poses a significant threat to the Bahamas, the East Coast of the United States, including the New York metropolitan area, and Atlantic Canada.

The ninth named storm, first hurricane, and first major hurricane of the 2011 season, Irene developed from a well-defined Atlantic tropical wave, which showed signs of tropical development east of the Lesser Antilles.

It developed atmospheric convection and a closed cyclonic circulation center, prompting the National Hurricane Center to initiate public advisories on the tropical cyclone late on August 20. Subsequent convective organization occurred as it passed the Leeward Islands, and by August 21 it moved very close to Saint Croix.

The next day, when this image was acquired, Irene made landfall near Puerto Rico, where high winds and intermittent torrents caused extensive property damage. The hurricane strengthened as it passed through southeastern Bahamas, becoming a major hurricane on August 24.

Hurricane Irene (09L) is still battering Abaco Island, while new watches and warnings have been issued for the east coast of the United States.

As of 5:00 PM EDT (2100 UTC), the hurricane was located about 575 mi (930 km) south of Cape Hatteras, North Carolina. The system is currently moving north-northwest or 335 degrees at 14 mph (22 km/h). Maximum sustained winds are 115 mph (185 km/h). Minimum central pressure (950 mb) 28.05 inches.

The government of the Bahamas has discontinued the hurricane warning for the central Bahamas. A hurricane warning has been issued for the coast of North Carolina from Little River Inlet northward to the Virginia border, including the Pamlico, Albemarle and Currituck Sounds. A tropical storm warning has been issued for the coast of South Carolina from Edisto Beach northward to Little River Inlet.

A hurricane watch has been issued for the east coast of the United States from the Virginia/North Carolina border northward to Sandy Hook, New Jersey, including Delaware Bay and the Chesapeake Bay south of Smith Point. A tropical storm watch has been issued for the Chesapeake Bay from Smith Point northward and the Tidal Potomac.
