THIS HAZARDOUS WEATHER OUTLOOK IS FOR PORTIONS OF SOUTH CENTRAL
ALABAMA...SOUTHWEST ALABAMA...NORTHWEST FLORIDA...SOUTHEAST
MISSISSIPPI AND THE COASTAL WATERS OF ALABAMA AND NORTHWEST FLORIDA

.DAY ONE...TONIGHT AND WEDNESDAY

LOW LEVEL MOISTURE HAS INCREASED RAPIDLY SOUTH OF A WARM FRONT THAT
MOVED ACROSS THE AREA THIS EVENING. ALONG THIS AXIS OF DEEPER
MOISTURE...A LINE OF THUNDERSTORMS WERE DEVELOPING AND MOVING
RAPIDLY NORTHEAST. SOME SEVERE STORMS ARE POSSIBLE WITH STRONG
DAMAGING WINDS AND ISOLATED TORNADOES. THE GREATEST RISK FOR A
SEVERE STORM THROUGH 2 AM WILL BE GENERALLY NORTH OF A WIGGINS TO
CHATOM LINE.

DUE TO THE RAPID MOVEMENT OF THE STORMS...RAINFALL TOTALS ARE NOT
EXPECTED TO BE EXCESSIVE BUT WITH THE HEAVIER RAINS ACROSS PARTS OF
SOUTHEAST MISSISSIPPI AND SOUTHWEST ALABAMA LAST NIGHT SOME PONDING
OF WATER AND LOCALIZED NUISANCE FLOODING MAY OCCUR.

A MODERATE STRONG ONSHORE FLOW IN ADVANCE OF A COLD FRONT WILL
CONTINUE OVER THE MARINE AREA TONIGHT. WINDS OVER THE MARINE AREA
WILL BECOME WESTERLY AND DIMINISH DURING THE DAY WEDNESDAY.

.DAYS TWO THROUGH SEVEN...WEDNESDAY NIGHT THROUGH MONDAY

A STRONG OFFSHORE FLOW WILL DEVELOP WEDNESDAY NIGHT OVER THE MARINE
AREA AS THE COLD FRONT MOVES SOUTH OF THE AREA.  MODERATE TO STRONG
WINDS WILL PERSIST OVER THE GULF WATERS THROUGH THE END OF THE WEEK.
THESE WINDS WILL CONTINUE TO POSE A HAZARD TO SMALL CRAFT.

ANOTHER LOW PRESSURE SYSTEM WILL DEVELOP OVER THE WESTERN GULF ON
FRIDAY AND TRACK ACROSS THE NORTHERN GULF LATE FRIDAY NIGHT INTO
SATURDAY. THERE WILL BE THE POTENTIAL FOR SOME LOCALLY HEAVY
RAINFALL WITH THIS SYSTEM...WHICH COULD RESULT IN MINOR FLOODING
ISSUES GIVEN THE EXPECTED SATURATED GROUND CONDITIONS OVER MUCH OF
THE AREA.

.SPOTTER INFORMATION STATEMENT...

ACTIVATION OF STORM SPOTTERS AND EMERGENCY MANAGEMENT MAY BE NEEDED
AT TIMES TONIGHT.
