ATLANTA — 11Alive meteorologist Wes Peery says that while it may seem unusual for a storm system to move from the mainland United States into the Gulf of Mexico that turns into a tropical storm system, this is the way most tropical systems develop. 

All you need is spinning motion in the atmosphere and a supportive warm tropical environment.

He says a trough of low pressure over portions of Tennessee, Georgia and Alabama is forecast to move southward toward the northern Gulf of Mexico over the next few days.

This will likely form into a broad tropical low-pressure area, where upper-level winds are expected to support development of a tropical system through the end of the week.

Historically, tropical systems that develop in the northern Gulf of Mexico tend to move into the lower portions of Alabama and Georgia, where large amounts of rainfall have fallen.

Based on model forecasts, by Friday, this particular weather system is likely to move into the Gulf and develop more tropical characteristics and begin to spin moisture into the Florida Panhandle region, as well as portions of southern Alabama and Georgia.

If it becomes a named tropical system, it would be named Barry.

Stay with the 11Alive Storm Trackers throughout the rest of the week as we track this weather system as it moves southward through the region and the possibility of its development as a full-fledged tropical system once it emerges over the Gulf of Mexico.
