OVER THE NEXT WEEK SURFACE HIGH PRESSURE WILL BE WEAKENING TO THE
NORTH OF THE ISLAND WHILE A CUTOFF LOW WEAKENS AND DRIFTS
WESTWARD. THIS WILL ALLOW AN INCREASE IN MOISTURE TO THE REGION
WHICH SHOULD SUPPORT SOME AREAS OF LOCALLY HEAVY RAINFALL.
EASTERLY TRADES WILL RETURN EARLY NEXT WEEK AS UPPER RIDING AND
SURFACE HIGH PRESSURE REBUILDS TO THE NORTH.
