A TROUGH MOVING OUT OF THE TROPICAL ATLANTIC WILL MOVE INTO THE

AS WELL AS NUMEROUS LANDSLIDES IN STEEP TERRAIN. SOME MAIN STEM

ALTHOUGH MOISTURE DIMINISHES MONDAY NIGHT...MODELS ARE INDICATING
UNSTABLE CONDITIONS THAT WILL ALLOW SOME THUNDERSTORMS TO FORM
TUESDAY...AND POSSIBLY WEDNESDAY...AFTERNOONS THAT WILL ALSO
EXASPERATE AN ALREADY DIFFICULT SITUATION.
RAINFALL AMOUNTS OF AT LEAST TWO TO FOUR INCHES WILL BE POSSIBLE
OVER THE AREA FROM SUNDAY NIGHT THROUGH TUESDAY AFTERNOON WITH
ISOLATED AREAS RECEIVING MORE THAN SIX...UP TO TEN INCHES OF
RAINFALL DURING THAT EXTENDED TIME PERIOD. THE HEAVIEST RAINFALL
