Tropical Storm Karen is quickly becoming disorganized as it heads for the Central Gulf Coast Sunday. The biggest problem will be flooding downpours but gusty winds and some storm surge could cause coastal problems.

Here are the likely effects from Tropical Storm Karen:


Rain will spread along the Gulf Coast through early Sunday. In general, 1-to-3 inches of rain are expected from the Gulf Coast into the Southeast through early Monday. A few isolated spots in southern Louisiana, Mississippi and Alabama could end up with 4-to-6 inches. Remember, if you approach a flooded roadway, it`s best to "Turn Around, Don`t Drown." The water is usually deeper than what it appears.


Sustained East winds will increase to 20 to 25 mph in southern Louisiana overnight. A few gusts in the rain bands will near 40 mph, causing sporadic power outages and minor structural damage to homes and businesses. These winds will diminish a bit in intensity as the storm loses its punch across southern Louisiana, Mississippi and Alabama. North of Interstates 10 and 12, winds will be weaker, with only a few power outages expected and no structural damage anticipated.

Storm Surge:

Storm surge will be greatest east of Karen`s center from Terrebonne Bay, La., to Cedar Key, Fla., with 1-to-3 feet expected if the surge occurs around high tide. This would bring water into dry areas along the coast. Elsewhere, storm surge is not expected to be a problem.

Severe Weather:

A bit of twisting winds in the atmosphere could briefly cause a weak tornado to spin up in a few rain bands associated with Karen. The best opportunity for a tornado to occur is to the right of the storm track, which includes southern Alabama to the Florida Panhandle.
