...HEAVY RAINFALL POSSIBLE THIS MEMORIAL DAY WEEKEND FOR SOUTH FLORIDA...  
 
A TROPICAL DISTURBANCE OVER THE YUCATAN CHANNEL IS FORECAST BY  
THE SHORT TO MEDIUM RANGE MODELS TO MOVE NORTHWARD INTO THE  
CENTRAL OR EASTERN GULF OF MEXICO THIS MEMORIAL DAY WEEKEND. THIS  
WILL ALLOW FOR DEEP TROPICAL MOISTURE TO MOVE NORTHWARD INTO SOUTH  
FLORIDA THIS MEMORIAL DAY WEEKEND WHICH IN TURN WILL LEAD TO THE  
POSSIBLE HEAVY RAINFALL. MOST AREAS WILL SEE BETWEEN 3 AND 5  
INCHES OF RAIN DURING THIS PERIOD, BUT THE WESTERN PORTIONS OF  
SOUTH FLORIDA COULD SEE AMOUNTS UP TO 7 INCHES OF RAINFALL.  
HOWEVER, TOTAL RAINFALL AMOUNTS COULD BE LOCALLY HIGHER WITH ANY  
THUNDERSTORMS THAT DO MOVE OVER SOUTH FLORIDA THIS MEMORIAL DAY  
WEEKEND.  
 
THE GROUNDS ACROSS SOUTH FLORIDA HAS ALSO BECOME SATURATED DUE TO  
THE HEAVY RAINFALL THAT OCCURRED OVER THE REGION LAST WEEK THROUGH  
EARLY THIS WEEK. IF THE FORECAST TREND CONTINUES FOR HEAVY  
RAINFALL, THEN A FLOOD WATCH MAY BE NEEDED FOR PORTIONS OF SOUTH  
FLORIDA FOR THIS MEMORIAL DAY WEEKEND. AT THIS TIME, THERE IS  
ALSO A MARGINAL RISK OF FLOODING ACROSS THE SOUTHERN AREAS OF  
FOR FRIDAY AND THE SOUTHERN AND WESTERN AREAS OF SOUTH FLORIDA ON  
SATURDAY FROM THE WEATHER PREDICTION CENTER (WPC).
