At 8:00 PM EDT (00:00 UTC), the eye of Hurricane Earl (07L) was located near latitude 27.2 North, longitude 73.5 West. Earl is moving toward the north-northwest near 18 mph (30 km/hr).

This motion is expected to continue tonight with a turn to the north on Thursday. On the forecast track, the core of the hurricane will approach the North Carolina coast by late Thursday, and move near or over the Outer Banks of that state by Thursday night.

Maximum sustained winds are near 135 mph (215 km/hr) with higher gusts.E arl is a category four hurricane on the Saffir-Simpson hurricane wind scale. Some fluctuations in intensity are likely tonight and Thursday, but a gradual weakening trend is anticipated thereafter.

Earl is a large hurricane. Hurricane force winds extend outward up to 90 miles (150 km) from the center, and tropical storm force winds extend outward up to 200 miles (325 km). The estimated minimum central pressure is 941 mb (27.79 inches).

There are various hazards affecting land. Tropical storm force winds are expected to reach the North Carolina coast within the warning area by Thursday afternoon with hurricane force winds occurring by late Thursday. Tropical storm force winds will likely reach the coast from Virginia northward to New Jersey by late Thursday night or early Friday.

A dangerous storm surge will raise water levels by as much as 3 to 5 feet above ground level within the hurricane warning
area and the lower Chesapeake Bay. Elsewhere within the tropical storm warning area, a storm surge will raise water levels by as much as 1 to 3 feet above ground level. Near the coast, the surge will be accompanied by large and destructive waves.

Rainfall accumulations of 2 to 4 inches, with isolated maximum amounts of 6 inches, are expected over portions of eastern North Carolina including the Outer Banks. With regards to surf, large swells from Earl will continue to affect the Bahamas
and the east coast of the United States through Friday. These swells will likely cause dangerous surf conditions and rip currents.
