A storm system sweeping across the Southeast is moving more slowly than anticipated, and will likely cause a wet morning commute for South Mississippi.
A flash-flood watch is in effect through late in the morning, and a small-craft advisory is in effect through 6 a.m.
The weather service expects total rainfall to be between 2 and 4 inches, but warns instantaneous and one-hour rainfall rates could be "very high."
There already has been a report of minor coastal flooding in Hancock County.
The storm system is expected to leave South Mississippi by late Wednesday, and temperatures will drop into the 50s. Nightly lows Thursday through Saturday are again expected to dip into the 40s with highs in the 60s.
