The National Hurricane Center on Saturday is tracking three systems in the Atlantic and one Gulf-bound system. As of the NHC’s 2 p.m. tropical outlook, the most likely would come from a system expected to form in the northwestern Caribbean and move into the Gulf of Mexico.

As we prepare for Francine, here's what to know about the developing system in the Atlantic and some other areas of low pressure.

A tropical depression could form next week as an area of low pressure in the Caribbean moves toward the Gulf of Mexico, the National Hurricane Center said Friday.
