NATIONAL WEATHER SERVICE SAN JUAN PR
ISSUED BY NATIONAL WEATHER SERVICE MIAMI FL
434 AM AST WED MAR 5 2025
DISCUSSION
UNSTABLE WEATHER CONDITIONS AND ABOVE NORMAL MOISTURE WILL PERSIST TODAY.
AS A RESULT, THE RH IS FORECAST TO BE ABOVE CRITICAL THRESHOLD
FOR THE MOST PART. WINDS WILL RANGE BETWEEN 10-15 MPH WITH HIGHER
GUSTS. ALTHOUGH FUELS ACROSS THE SOUTHERN COASTAL PLAINS REMAIN
DRY, THE WINDS AND RHS WILL LIKELY REMAIN OUTSIDE OF THE CRITICAL
THRESHOLDS TODAY AND LIKELY PERSIST THROUGH THE END OF THE
WORKWEEK. THEREFORE, LOW FIRE DANGER IS FORECAST FOR TODAY.
