Tropical Depression Nine has formed off the coast of Mexico in the Gulf of America, and forecasts show it will be the Atlantic's first hurricane of this historically quiet season.

The system is currently getting better organized, and the National Hurricane Center (NHC) said it is forecast to bea tropical Storm on Wednesday and a hurricane on Thursday. 

The NHC said the system is likely to be a Category 2 hurricane by Friday night, with estimated winds at 100 mph.

A tropical depression has maximum sustained winds of 38 mph or less, and unlike tropical storms and hurricanes, tropical depressions are identified with numbers and not names.

Regardless of tropical development, forecasts show another round of heavy rain headed to parts of the Florida and Louisiana coasts by the weekend.

NOAA's Weather Prediction Center (WPC) has issued a Level 2 out of 4 flash flood risk for parts of the Southeast on Friday and Saturday.

Meanwhile, Gulf water temperatures are currently at their warmest levels on record dating back to 1982. Warm waters are conducive for tropical development.

September ended without a hurricane for the first time in 32 years, despite it being the climatological peak of the season.
