Tropical Depression #2 forms in the Gulf of Mexico

MIAMI -- Tropical Depression #2 formed in the Gulf of Mexico on Thursday afternoon on the first day of Hurricane Season. 

TD #2 is swirling off the state's coast in the Gulf of Mexico and it is expected to bring more wet weather to South Florida.

The National Hurricane Center predicted the depression could strengthen into a tropical storm Thursday night or Friday. But the system should begin to weaken by Friday night and degenerate into a remnant low by Saturday. Tropical storms have winds of at least 39 mph; anything 74 mph or higher is designated a hurricane.

The hurricane season runs through Nov. 30. Last year's season had 14 named storms, with extensive damage caused by Hurricanes Ian, Nicole and Fiona.

CBS News Miami meteorologist Lissette Gonzalez said the storm will impact South Florida.

"We have a NEXT Weather Alert Day because more rain is on the way," she said, adding that the storms are expected through early afternoon into the evening hours.

The National Weather Service has issued a flood watch for Miami-Dade and Broward that extends until 8 p.m. Friday because of an already saturated ground.

"We could see an additional 2-6 inches of rain and the ground is already saturated," she said. "The ground can't take anymore."

The high temperature is expected to top out in the upper 80s and there is an 80 percent chance of precipitation, Gonzalez said. 

The chance for rain continues into Friday before drier air arrives for the weekend.

Thursday marks the official start of hurricane season and federal forecasters said there is a 20 percent chance the system in the Gulf could develop into an organized storm.
