Tropical Weather Outlook:
There is a 60% chance of a tropical depression forming over the next 48 hours across the northeastern Gulf, near the Florida Panhandle. Recent satellite-wind data and nearby surface observations indicate that an area of low pressure is slowly becoming better defined. Gradual development of this system is forecast, and a tropical depression could form over the next couple of days as the system moves slowly northward or northwestward. Interests along the northern Gulf coast from Florida, Alabama, Mississippi, to Louisiana should monitor the progress of this system as it is expected to bring heavy rain to portions of that region during the next several days.

Confidence in the Extended Outlook:
Confidence is generally good for the earlier outlook, with broad agreement on the large-scale pattern but with increasing uncertainty by mid- to late week in the timing and placement of eastern U.S. systems. Confidence decreases to about average later as forecast signals weaken and model spread increases.
