Computer Models have changed drastically in the last 24 hours. Experts are not certain if the high pressure ridge that is over the Eastern United States will weaken allowing Hanna to turn north over the next few days.
Sunday, August 31, 2008 – 8:00 AM EDT advisory from AccuWeather
Tropical Storm Hanna was located near 23.2 north, 68.5 west, or 155 miles east-northeast of Grand Turk Island. Hanna is moving to the west-northwest at 8 mph with maximum-sustained winds estimated near 60 mph.
Tropical storm-force winds extend outward up to 200 miles. The estimated central pressure in Hanna is 999 millibars, or 29.50 inches.
A tropical storm warning is in effect for the Turks and Caicos.
A tropical storm watch is in effect for the southeastern Bahamas.
Hanna continues to interact with an upper-level low to the west. The interaction should prevent Hanna from intensifying through Monday. While rapid strengthening is unlikely, Hanna could reach hurricane strength by Tuesday as it moves slowly to the west.
