On August 30 at 11:00 AM AST, Earl (07L) intensified into a category 3 hurricane, making it the second major hurricane of the season after Hurricane Danielle (06L). Later that day, Earl intensified further into a category 4 hurricane and could further develop into a category 5 hurricane.

Earl is the first Cape Verde-type hurricane to affect the Leeward Islands since Hurricane Georges. It is currently predicted to affect the Grand Strand of South Carolina, Outer Banks of North Carolina and possibly Atlantic Canada.

As of 1100 PM AST (0300 UTC), the center of Hurricane Earl was located near latitude 23.0 North, longitude 69.9 West.E arl is moving toward the northwest near 15 mph (24 km/hr).

This general motion is expected to continue on Wednesday with a gradual turn to the north-northwest thereafter. On the forecast track, the core of the hurricane will be passing well east and northeast of the Turks and Caicos Islands Tuesday night and northeast of the Bahamas Wednesday.

Maximum sustained winds are near 135 mph (215 km/hr) with higher gusts. Earl is a category four hurricane on the Saffir-Simpson hurricane wind scale. Little change in strength is expected through Wednesday.

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).  Estimated minimum central pressure is 940 mb (27.76 inches).

Hazards affecting land include winds, storm surges and rainfall. Tropical storm conditions are probably occurring in the vicinity of the Turks and Caicos Islands.
