FIRE WEATHER PLANNING FORECAST FOR PUERTO RICO
NATIONAL WEATHER SERVICE SAN JUAN PR
537 AM AST TUE MAY 21 2013
.DISCUSSION...THE EASTERLY WIND FLOW IN COMBINATION WITH LOCAL
OROGRAPHIC EFFECT AND A WEAK TROPICAL WAVE PASSING SOUTH OF THE
REGION ACROSS THE CARIBBEAN WATERS WILL AID IN THE DEVELOPMENT OF
SHOWERS AND THUNDERSTORMS ACROSS EASTERN PUERTO RICO THIS MORNING
AND ACROSS PARTS OF THE INTERIOR AND WEST SECTIONS OF THE ISLAND
DURING THE AFTERNOON. THE MODERATE TO STRONG EASTERLY WIND FLOW
WILL PREVAIL ACROSS THE ISLANDS. RELATIVE HUMIDITY VALUES WILL
THEREFORE BE WELL ABOVE CRITICAL THRESHOLD LEVELS AND THE RISK OF
FIRE DANGER WILL REMAIN VERY LOW TODAY.
