Hanna to remain a tropical storm for a while.
Hanna is moving toward the northwest and is encountering wind sheer which will impede intensification. This situation is expected to continue for a couple of days. Somewhere over the weekend, Hanna could strengthen into a hurricane.
Computer models agree that heading into the middle of next week Hanna will begin to shift back to the southwest toward Florida but where Hanna will actually wind up is quite uncertain.

Tropical Storm Hanna was located near 21.7 North, 62.3 West or 245 miles northeast of the northern Leeward Islands. Hanna is moving to the west-northwest at 14 mph with maximum sustained winds estimated at near 50 mph. The estimated pressure in Hanna is 1000 millibars or 29.53 inches. Hanna is experiencing strong westerly shear and will probably not intensify much during the next 24 hours.
Tropical Storm Hanna has strengthened recently with strong thunderstorms again erupting near its center. Shear has also relaxed as the upper level low to the west of Hanna moves west-southwest and weakens within the next 24 hours. Hanna will not be a direct threat to land. However, moisture flowing into the storm will pass over the Leeward Islands tonight and tomorrow and this could bring parts of those islands gusty winds and 1-3 inches of rain. Hanna will move west-northwest to northwest and stay east of the Bahamas this weekend.
