FIRE WEATHER PLANNING FORECAST FOR PUERTO RICO
NATIONAL WEATHER SERVICE SAN JUAN PR
554 AM AST SAT MAY 18 2013
.DISCUSSION...HIGH PRESSURE ALOFT WILL BUILD ACROSS THE REGION
TODAY TO MAINTAIN OVERALL DRY AND SUBSIDENT AIR MASS. HOWEVER...
STILL POCKETS OF LOW LEVEL MOISTURE AVAILABLE TO AID IN DIURNALLY
INDUCED CONVECTION MAINLY ACROSS PARTS OF THE INTERIOR SECTIONS OF
PUERTO RICO. LIGHT EASTERLY TRADES WILL ALLOW FOR LOCAL SEA BREEZE
CONVERGENCE AND MAY HELP ENHANCE A FEW SHOWERS IN ISOLATED SPOTS.
AN UPPER LEVEL SHORT WAVE TROUGH AND AND WEAK EASTERLY PERTURBATION
WILL MOVE JUST SOUTH OF THE LOCAL AREA LATE SUNDAY OR MONDAY. THIS
SHOULD INCREASE TOPICAL MOISTURE ADVECTION AND THEREFORE INCREASE
THE CHANCE FOR MORE WETTING RAINS ACROSS THE ISLANDS. RELATIVE HUMIDITY
VALUES WILL THEREFORE REMAIN WELL ABOVE CRITICAL THRESHOLD LEVELS
AND THE RISK OF FIRE DANGER WILL REMAIN LOW.
