8:00 PM Advisory from AccuWeather
Hurricane Gustav is located near 22.7 north83.4 west or 65 miles west southwest of Havana Cuba. Maximum sustained winds are near 150 mph with higher gusts. This makes Gustav an extremely dangerous Category 4 hurricane. Hurricane-force winds extend outward from the center for 70 miles and tropical storm-force winds extend 175 miles from the center. The estimated central pressure is 941 mb, or 27.79 inches. Gustav will probably remain a strong category 4 hurricane as it moves over the relatively flat area of western Cuba early tonight. Once it moves back out over open water north of western Cuba late tonight and early Sunday morning it could become a category 5 hurricane.
Gustav is moving over western Cuba the first part of tonight, with winds of 150 mph and wind gusts even higher. Rainfall amounts of 6 to 12 inches likely across this area and local amounts of 20 inches possible. Rainfall totals on the order of 1 to 3 inches is expected for the Florida Keys and extreme South Florida by Sunday. The hurricane will also bring a storm surge as high as 14 to 19 feet above normal tide to areas close to where the eye passes over western Cuba this evening. Weather conditions over the Cayman Islands will slowly improve as Gustav moves northwest and away from those islands tonight.
The northwest movement of Gustav is expected to continue through Sunday. During Sunday night and Monday a large area of high pressure is expected to build from the Ohio Valley southward toward the deep South. The strength and orientation of this high pressure area, along with how quickly it moves east, will determine when and where Gustav makes landfall along the Louisiana coast. This high pressure area might slow the forward progress of Gustav and may even deflect it slightly to a more westerly course. So all interests along the Gulf Coast need to keep a close watch on the future progress of this impending dangerous hurricane. This is especially true from the extreme western Florida Panhandle to the southeastern Texas coast.
