Hurricane Irene Nears Landfall

Hurricane Irene Nears Landfall

Irene, the first hurricane of the 2011 Atlantic season, was poised on August 26 to be the first to make landfall in the United States since 2008. More than 50 million people were estimated to lie within the path of the storm as it headed toward the major U.S. population centers of Norfolk, Washington, Baltimore, Philadelphia, New York, and Boston.

The coast of North Carolina and Virginia braced for a possible Category 3 storm, the strongest since 1996. Irene also appeared likely to become the first hurricane-force storm to make landfall in New England since 1991.

The animation above shows the progress of Irene from 21:45 Universal Time (5:45 p.m. EDT) on August 23 through 16:32 UTC (12:32 p.m. EDT) on August 26, 2011. The animation is built from still images acquired every 5–15 minutes by the GOES-East satellite.

After developing into a tropical storm on August 20, Irene moved west and north to buffet Puerto Rico, Turks & Caicos, and he Bahamas. The storm brought extreme winds, storm surges, and flooding rains to each island before taking aim at the Carolina coast of the U.S.

At 11 a.m. Eastern Daylight Time (EDT) on August 26, 2011, the National Hurricane Center reported that Hurricane Irene was located at 30.7 degrees North latitude, 77.3 degrees West longitude, about 330 miles (530 kilometers) south-southwest of Cape Hatteras, North Carolina. The storm packed sustained winds of 105 miles (165 kilometers) per hour and was moving north at 14 miles (22 kilometers) per hour.

Forecasters noted at 11 a.m. on Friday that hurricane intensity was likely to remain stable for much of the day, with some potential (via warm Gulf Stream water) to intensify a bit. The storm should eventually lose some energy from southwesterly wind shear and the movement into cooler northern waters. Nonetheless, hurricane warnings and watches were posted from the South Carolina coast to Maine.
