Forecasters issued a flood watch across the Mississippi Coast through Friday and said the deluge could swamp rivers, streams and low-lying areas. The National Weather Service predicted 3 to 5 inches would fall south of Interstate 10 between Wednesday and Saturday and said some spots could get up to 10 inches in a worst-case scenario.

A tropical weather system near the Florida Panhandle is showing a moderate chance of becoming a tropical depression.

Yet another flooding event is possible, this time along the Gulf Coast on Thursday and Friday, as a tropical disturbance tracks toward Louisiana. The chance that the disturbance will turn into a tropical storm appears slimmer than it was earlier this week.
