FIRE WEATHER PLANNING FORECAST FOR SOUTHWESTERN CALIFORNIA
NATIONAL WEATHER SERVICE LOS ANGELES/OXNARD CA
341 PM PDT WED SEP 17 2025
...WIDESPREAD OFF AND ON SHOWERS TONIGHT THROUGH THURSDAY OR FRIDAY,
WITH RISKS OF LOCALIZED HEAVY RAIN AND STRONG WINDS...
DISCUSSION
THE REMNANTS OF WHAT WAS TROPICAL STORM MARIO WILL MOVE THROUGH
CALIFORNIA BY FRIDAY. ISOLATED THUNDERSTORMS ARE EXPECTED
THROUGH FRIDAY. THE THREAT FOR ISOLATED DRY LIGHTNING IS DECREASING AS
THE THREAT FOR ISOLATED HEAVY RAIN INCREASES. THE PERIOD OF MOST CONCERN
IS LATER TONIGHT THROUGH THURSDAY, AS THE BULK OF THE MOISTURE MOVES
THROUGH. ANY HEAVY SHOWER COULD PRODUCE ISOLATED FLASH FLOODING
ANYWHERE, WITH THE HIGHEST RISKS IN THE MOUNTAINS WHERE A FLOOD WATCH
IS IN EFFECT. RECENT BURN SCARS ARE ALSO AT RISK FOR A DEBRIS FLOW,
WITH A SMALL BUT NON-ZERO CHANCE OF A SIGNIFICANT DEBRIS FLOWS IF AN
UNFORTUNATELY HEAVY SHOWER FORMS AND SLOWS RIGHT OVER A BURN SCAR. THE
POTENTIAL FOR GUSTY AND BRIEF WINDS ALSO EXISTS THROUGH THE PERIOD.
THIS IS ESPECIALLY TRUE ON THURSDAY AS THE CORE OF SYSTEM APPROACHES
WITH SOMEWHAT UNPREDICTABLE RESULTS. THE TROPICAL MOISTURE AND
ASSOCIATED RISKS SHOULD DECREASE FRIDAY INTO SATURDAY, BUT THERE IS A
ANOTHER CHANCE OF ANOTHER TROPICAL SURGE SOMETIME SUNDAY THROUGH
TUESDAY OF NEXT WEEK, ALTHOUGH THE PROJECTIONS SUGGEST SOMETHING OF A
LESSER DEGREE THAN OUR CURRENT SURGE.
