TROPICAL DISCUSSION - INTERNATIONAL DESKS
NWS WEATHER PREDICTION CENTER COLLEGE PARK MD
845 AM EST MON DEC 22 2014

PRELIMINARY DISCUSSION FOR PUERTO RICO AND THE USVI. MID/UPPER
LEVEL RIDGE IS TO REMAIN WELL ESTABLISHED ACROSS THE FORECAST AREA
DURING THE NEXT FIVE TO SEVEN DAYS...SUSTAINING A LARGE SCALE
SUBSIDENT PATTERN ACROSS THE FORECAST AREA. THIS RIDGE REFLECTS
QUITE WELL AT LOW LEVELS OF THE ATMOSPHERE...CENTERING TO THE
SOUTH-SOUTHEAST OF BERMUDA. EARLY IN THE CYCLE THIS IS TO FAVOR
BRISK EASTERLY WINDS ACROSS THE FORECAST AREA. BUT THROUGH MIDDAY
ON WEDNESDAY THE WINDS ARE TO BACK TO THE NORTHEAST. ALTHOUGH
GENERALLY DRY AND STABLE CONDITIONS ARE TO PREVAIL...THE
NORTHEASTERLY WINDS ARE TO LIKELY FAVOR AN INCREASE IN TRADE WIND
SHOWER ACTIVITY AS COOLER AIR ADVECTS OVER WARM WATERS.

TROPICAL/EASTERLY WAVES INITIALIZED AT 12UTC
INITIAL  24     36     48     60     72     84     96     TYPE
