PUERTO RICO THAT IS FORECAST TO REMAIN RELATIVELY STATIONARY THE
NEXT FEW DAYS WITH AN UPPER LEVEL RIDGE FORECAST TO EXTEND ACROSS
THE FLORIDA PENINSULA AND ADJACENT WATERS AND HIGH SURFACE
PRESSURE REMAINING ACROSS THE REGION THROUGH THIS PERIOD. SO THE

PENINSULA...ALTHOUGH WITH MAINLY MODERATE SOUTHEASTERLY FLOW MOST
OF THE ACTIVITY IS EXPECTED TO BE IN THE INTERIOR AND WESTERN

LESSER ANTILLES COULD ENTER THE REGION ON THURSDAY AND MIGHT
CONTAIN A LOW LEVEL SAHARAN AIR LAYER. MODEL SOUNDINGS INDICATE A
DRIER AIR LAYER IN THE 850-700 HPA LAYER BY THURSDAY. SO HAZY
