DISCUSSION
WEATHER CONDITIONS ARE EXPECTED TO GRADUALLY BECOME
MORE UNSETTLED AS A SURFACE AND UPPER-LEVEL TROUGH REMAIN OVER THE
REGION. WHILE MOST SHOWER AND THUNDERSTORM ACTIVITY SHOULD REMAIN
OVER THE SURROUNDING WATERS OVERNIGHT, A FEW SHOWERS COULD MOVE
OVER THE COASTAL FIRE AREA, THOUGH COVERAGE AND DURATION REMAIN
UNCERTAIN. ANY RAINFALL IS EXPECTED TO BE BRIEF AND UNEVEN, WITH
LIMITED IMPACT ON FUELS, WHICH REMAIN VERY DRY DUE TO RECENT
RAINFALL DEFICITS AND LOW SOIL MOISTURE. WINDS WILL BE GENERALLY
LIGHT FROM THE EAST AT 5 TO 10 MPH, BUT NEARBY SHOWERS OR
THUNDERSTORMS COULD PRODUCE BRIEF GUSTY AND ERRATIC WINDS UP TO
AROUND 30 MPH, ALONG WITH LIGHTNING. OVERALL, DRY FUELS,
LIGHTNING POTENTIAL, AND LOCALIZED GUSTY WINDS MAY CONTRIBUTE TO
PERIODS OF INCREASED FIRE BEHAVIOR.
