After finally becoming Tropical Storm Debby on Saturday evening, the tropical system off the west coast of Florida has become stationary.

The tropical system building in the Gulf of Mexico for several days became the fourth named storm of the 2012 Hurricane Season.

At the 8 p.m. advisory, Debby slowed from 6 mph to nearly stationary over the central Gulf of Mexico. At 11 p.m. Saturday, there were no changes to watches or warnings.

"It's moving so slowly and it will probably affect us through Monday, and possibly even Tuesday," Bay News 9 Meteorologist Diane Kacmarik said.

Debby has maximum sustained winds of 50 mph. The storm's preliminary track is expected to move toward Louisiana and Texas. The center of the storm's circulation is roughly 250 miles south-southeast of the mouth of the Mississippi River, off the western coast of Florida.

A Tropical Storm Warning is in effect for parts of the Louisiana coast, from the mouth of the Pearl River to Morgan City, La. The warning does not yet include New Orleans or Lake Pontchartrain.

"The storm is not expected to move over the next 24 hours or more. The movement of the storm will depend on how large it grows," Kacmarik said Saturday night. "If it moves to the east -- toward Florida -- it will see a lot of shear and bring down its intensity. If it moves to the west, it will have more time to develop."

The current forecast cone for Debby has the tropical storm drifting north at 6 mph and then drifting back toward the west.

"Some Gulf oil rigs are being evacuated due to threat of Debby," according to Bay News 9 Chief Meteorologist Mike Clay. "Some Louisiana coastal flood gates are already being closed."

Some other tracks have the system heading west into Mexico, while other tracks send the system east into Florida. Clay said it is difficult to determine a specific location at which the system starts, and as a result, the tracks predicted by each model are drastically different from one another.

A recon plane flew into the system Saturday afternoon, giving meteorologists better idea about the conditions inside the system, including data on where it is located.

The Bay News 9 Weather Experts will have LIVE reports through the weekend as Debby develops.
