...SHOWERY WEATHER WITH LOCALLY HEAVY DOWNPOURS FOR THE MARIANAS  
SUNDAY EVENING THROUGH MONDAY NIGHT...|  
 
A DEVELOPING TROPICAL DEPRESSION AND ITS ASSOCIATED MONSOON TROUGH  
WILL GRADUALLY MOVE OVER THE MARIANA ISLANDS FOR THE NEXT COUPLE  
OF DAYS. THESE FEATURES WILL GENERATE SHOWERY CONDITIONS WITH  
LOCALLY HEAVY DOWNPOURS SUNDAY NIGHT THROUGH TUESDAY NIGHT. MODEL  
GUIDANCE HAS SUGGESTED RAINFALL OF 3 TO 6 INCHES ACROSS THE  
MARIANAS AT THAT TIME.  
 
THIS DEVELOPING SITUATION WILL CONTINUE TO BE MONITORED CLOSELY AND  
FLOOD WATCHES AND ADVISORIES WILL BE ISSUED WHEN NECESSARY. HEAVY  
DOWNPOURS COULD PRODUCE FLOODING IN URBAN AND LOW-LYING  
AREAS...AND IN THE RIVERS AND STREAMS.  
 
NOW IS A GOOD TIME TO CLEAR DRAINAGE AREAS AND UN-BLOCK CLOGGED STORM  
DRAINS IN YOUR AREA TO MINIMIZE THE CHANCE OF FLOODING. RESIDENTS  
LIVING NEAR RIVERS AND STREAMS NEED TO REVIEW PLANS FOR PROTECTING  
PROPERTIES.  
 
THIS PRODUCT WILL NOT BE UPDATED AND WATCHES AND WARNINGS MAY BE  
ISSUED AS REQUIRED.
