Odds increase for development of Invest 91L in the Gulf, with heavy downpours expected in Southeast

Development odds for Invest 91L are increasing in the Gulf of America right off the coast of Florida. 

The invest has a low chance of development over the next two days, but medium chances of development over the next week, as it moves slowly to the north and north-west, according to the National Hurricane Center (NHC). 

Invest 91L was designated on Saturday by the NHC. 

The term "invest" is used every hurricane season in the Atlantic and the Eastern and Central Pacific basins, accompanied by a number from 90 to 99 and either the suffix "L," "E" or "C," respectively. It is used to identify areas they are investigating for possible development into a tropical depression or tropical storm within the next seven days. 

Rain from this system is already falling in Florida, with showers reported in Tampa and along Florida's northwestern coast. 

Those along Florida's panhandle and along the western coast as well as in coastal Alabama should pay attention to the progress of this system, the NHC said. 

On Friday, the NHC finally placed an "X" on the map, which means there is officially an area of low pressure to track. Not only is there an area of low pressure, but it formed farther away from the coast than originally anticipated, according to the FOX Forecast Center.

Most impacts will come in the form of rain. Wind impacts are not expected unless a tropical depression or tropical storm forms. 

If the system develops into a tropical storm, it'll be given the name Bertha. 

The Atlantic hurricane season runs from June 1 to November 30.
