The system could end up bringing a lot of rain to the Gulf Coast, including Alabama, according to forecasters. The National Hurricane Center said there is a 30 percent probability of a tropical depression forming in the next week in the Gulf, an increase from 20 percent the past few days.

A disorganized low-pressure area off Florida's east coast is showing increasing chances of becoming a tropical depression or tropical storm later in the week, the National Hurricane Center said. Even now, it's already having an influence on Florida weather with isolated torrential rain.
