Tropical Depression Nineteen has formed in the Caribbean Sea and is forecast to continue strengthening, according to the National Hurricane Center.

Tropical Storm Sara formed in the Caribbean Sea on Thursday, but the National Hurricane Center says there's a chance it won't reach hurricane strength.

First, Hurricane Debby made landfall as a Category 1 storm on Aug. 5, then came Hurricane Helene on Sept. 26 as a Category 4, and just less than two week later, Hurricane Milton arrived as a Category 3.
