LOUISIANA WEATHER - August 9, 2010

TROPICAL WEATHER:
As of 8:05 am CDT, National Hurricane Center Reports:

A broad surface low over southern Florida is producing a large area of disorganized showers and thunderstorms over the northwestern Bahamas across the Florida Keys into the southeastern Gulf of Mexico. Upper-level winds are forecast to become more favorable for development over the next couple of days as the system moves to the west or west-northwest at 5 to 10 mph over the Gulf of Mexico. There is a low chance, about 20 percent of this system becoming a tropical cyclone during the next 48 hours, though conditions could become a little more conducive for development after that time. The West Feliciana Parish OHSEP in conjunction with the National Weather Service is monitoring this system and will provide updates as necessary.

A well-defined low pressure system located about 950 miles east-northeast of the Leeward Islands is moving west-northwestward at 10 to 15 mph. Shower and thunderstorm activity has recently developed closer to the center and any significant organization of the thunderstorms during the next couple of days could result in the formation of a tropical depression. There is a high chance, about 70 percent of this system becoming a tropical cyclone during the next 48 hours.
This storm is expected to remain in the Atlantic.

A Tropical Wave extends across West Africa from 18N15W to 8N12W moving west near 17mph.

A Tropical Wave is along 15N36W to 6N38W moving west at 17mph.

HAZARDOUS WEATHER: An upper level ridge of high pressure remains in place across the southern plains, resulting in continued oppressively hot conditions across the region.
