System likely to develop, prompts warnings for Gulf Coast

Warning includes Louisiana coast

Portions of the Gulf Coast are under a tropical storm warning, including all of the Southeast Louisiana coast.

"A Tropical Storm Warning is in effect for Intracoastal City to the Mouth of the Pearl River," according to the National Hurricane Center. "A Tropical Storm Warning means that tropical storm conditions are expected somewhere within the warning area, in this case within the next 24 to 36 hours."

An area of disturbed weather in the southern Gulf of Mexico has not become a depression or storm yet, but the National Hurricane Center says it is likely to develop by tomorrow.

"A broad area of low pressure extends from north of the Yucatan Peninsula across adjacent portions of the southern Gulf of Mexico," according to an advisory.

While it does not have a closed circulation, the system does have some significant energy.

"This system is producing a large area of disorganized shower and thunderstorm activity well east and northeast of the low over much of the eastern Gulf of Mexico."

The Hurricane Center says that satellite wind data indicate that tropical-storm-force winds are covering 100 to 150 miles northeast of the broad low. 

Forecasters say conditions are going to get better for the system to develop.

"Upper-level winds are expected to be marginally conducive for some additional development of this system during the next day or two while it moves northward to northwestward into the central Gulf of Mexico."

Authorities expect a tropical or subtropical cyclone to form by late Tuesday.

"Regardless of development, interests along the U.S. Gulf Coast from the central Texas coast to the western Florida Panhandle should monitor the progress of this system."



WIND: Tropical storm conditions are expected to first reach the coast within the warning area on Tuesday. Tropical storm conditions are possible in the watch area on Wednesday.

RAINFALL: The disturbance is expected to produce total rain accumulations of 4 to 8 inches with isolated maximum amounts of 10 inches over southeastern Louisiana, southern Mississippi and Alabama, and the western Florida Panhandle through Wednesday evening.
