30% ACROSS MUCH OF THE REGION EACH AFTERNOON THROUGH TUESDAY. THE

THERE IS A 40% TO 50% CHANCE FOR LOCALIZED AREAS TO DROP BELOW
20%. ADDITIONALLY, 10-HOUR FUELS AREAWIDE WILL DROP TO NEAR 10%
THROUGH TUESDAY AS WARM, DRY WEATHER REMAINS SITUATED ACROSS THE

THEREFORE, FIRE DANGER WILL REMAIN ELEVATED THROUGH THE NEXT FEW
DAYS UNTIL HIGHER GULF MOISTURE CAN ARRIVE WEDNESDAY.
FORTUNATELY, 20-FOOT WINDS ARE FORECAST TO REMAIN UNDER 10 MPH
THROUGH THIS PORTION OF THE FORECAST. WETTING RAIN CHANCES RETURN
THURSDAY AS A LOW PRESSURE SYSTEM APPROACHES THE REGION, BUT THIS
PORTION OF THE FORECAST IS STILL UNCERTAIN AND PRECIPITATION
CHANCES ARE EXPECTED TO CHANGE IN THE COMING DAYS.
