Forecasters now give an area of disturbed weather in the Gulf of Mexico a 50 percent chance of becoming a tropical depression, and the National Hurricane Center says it could become a tropical storm before moving into Florida.
Louisiana Climatologist Barry Keim says conditions are becoming more favorable for development.
"We've had lots of wind shear aloft which has limited the development of this particular system," he explained. "But today that shear is expected to relax a little bit, which may allow strengthening."
The Hurricane Center says heavy rains are likely from Cuba through the Florida Keys and the Florida peninsula during the couple of days.
The low pressure area has struggled to get its act together so far.
"The circulation remains poorly-defined," an advisory from the Hurricane Center stated. "Environmental conditions could become a little more conducive for development during the next day or so...and a tropical depression or storm could form before the system moves northeastward over northern Florida late Thursday or Thursday night."
Forecasters say the system is not expected to have much impact on Louisiana.
"We are going to see very few impacts other than tides one to two feet above normal toward the end of the week and over the weekend," WWL TV Meteorologist Laura Buchtel.
