Discussion and 48-hour Outlook

At 800 pm EDT (0000 UTC), the eye of Hurricane Irene was located near latitude 27.7 north, longitude 77.4 west. Irene is moving toward the north-northwest near 14 mph (22 km/h).  This motion is expected to continue tonight with a turn toward the north Friday. On the forecast track, Irene will continue to move away from the Northwestern Bahamas tonight, and the core of the hurricane will pass well offshore of the East Coast of Central and Northern Florida later tonight and early Friday.  The hurricane is forecast to approach the coast of North Carolina on Saturday.

Maximum sustained winds remain near 115 mph (185 km/h) with higher gusts.  Irene is a Category Three hurricane on the Saffir-Simpson Hurricane Wind Scale.  Some strengthening is possible tonight and Friday.

Irene is a large tropical cyclone.  Hurricane force winds extend outward up to 80 miles (130 km) from the center, and tropical storm force winds extend outward up to 290 miles (465 km).

The latest minimum central pressure estimated from an Air Force Reconnaissance Aircraft was 946 mb (27.93 inches).

Hazards Affecting Land

Wind...Hurricane and Tropical Storm conditions are beginning to subside over the Northwestern Bahamas. Tropical storm force winds are expected within the southern portion of the warning area along the United States East Coast by late Friday.  Hurricane force winds are expected to first reach the hurricane warning area by Saturday.

Storm Surge…water levels will gradually subside over the Northwestern and Central Bahamas tonight. Along the Eastern Coast of the United States, an extremely dangerous storm surge will raise water levels by as much as 5 to 10 feet above ground level within the hurricane warning area including the Albemarle and Pamlico Sounds.  Near the coast, the surge will be accompanied by large, destructive, and life-threatening waves. Irene also has the potential to produce significant storm surge flooding within the hurricane watch area including portions of the Chesapeake Bay, tributaries, and the eastern shore.

Rainfall...Irene is expected to produce rainfall accumulations of 6 to 12 inches over the Northern Bahamas.  Storm total rainfall amounts of 6 to 10 inches with isolated maximum amounts of 15 inches are expected over portions of eastern North Carolina and in the Mid-Atlantic States along the path of Irene.

Surf...swells generated by Irene are affecting portions of the coast of the Southeastern United States.  These swells will cause life-threatening surf and rip current conditions.
