A tropical depression has formed in the Atlantic Ocean west of the Cape Verde Islands, and it could become a tropical storm later Thursday, according to the National Hurricane Center.
At 11 a.m. EDT, the depression was located about 870 miles west of the Cape Verde Islands, moving to the northwest at 13 mph. Maximum sustained winds were 35 mph, with gusts reaching higher speeds.
The system was not expected to threaten land.
Meanwhile, South Florida may see some heavy rain from a tropical disturbance near the northwestern Bahamas, which has become more concentrated on Thursday. Also, the circulation has become "a little better refined," the Hurricane Center said.
Never miss a local story.
"Some additional development could occur before upper-level winds become less conducive tonight. The low is expected to move generally westward across the southern Florida Peninsula into the eastern Gulf of Mexico during the next couple of days. Regardless of development, this low will bring locally heavy rains to portions of southern Florida and the Florida Keys during the next couple of days," the Hurricane Center said.
At least one computer model has the system aiming for the Tampa Bay region before entering the Gulf of Mexico.
The chance of development is 20 percent during the next 48 hours, and 30 percent during the next five days, the Hurricane Center said.
