A WINTER STORM WILL BRING WIDESPREAD MODERATE TO HEAVY
PRECIPITATION AND MOUNTAIN SNOW ON MONDAY, FOLLOWED BY SCATTERED
SHOWERS AND A SLIGHT CHANCE OF THUNDERSTORMS MONDAY EVENING INTO
EARLY TUESDAY MORNING. LIGHT SHOWERS CONTINUE TUESDAY, THEN
ANOTHER SHORT WAVE WILL PRODUCE MORE ORGANIZED PRECIPITATION WITH
LOWER SNOW LEVELS ON WEDNESDAY. ADDITIONAL LIGHT SHOWERS ARE
POSSIBLE THURSDAY INTO EARLY FRIDAY. PRECIPITATION CHANCES ARE
CURRENTLY BELOW 15% FOR FRIDAY AND SATURDAY, BUT THERE IS THE
POTENTIAL FOR LIGHT SHOWERS AT TIMES.
PEAK HOURLY RAINFALL RATES DURING THE FRONTAL PASSAGE ON MONDAY WILL
RANGE FROM 0.40-0.70" PER HOUR. CURRENT FORECAST RAINFALL TOTALS
FOR MONDAY AND TUESDAY WILL BE 0.80- 1.50" FOR THE COAST AND
VALLEYS, 1-3.5" FOR THE MOUNTAINS, 0.20-1.00" FOR THE HIGH
DESERT, AND 0.10-0.50" FOR THE LOW DESERTS, LOCALLY UP TO 1" NEAR
THE SAN GORGONIO PASS IN THE FAR NORTHERN COACHELLA VALLEY. MUCH
OF THIS RAIN WILL FALL ON MONDAY, WITH LIGHT TO LOCALLY MODERATE
SHOWERS POSSIBLE ON TUESDAY. A SLIGHT RISK OF EXCESSIVE RAINFALL
IS FORECAST FOR ORANGE COUNTY INTO THE LOWER SLOPES OF THE SAN
BERNARDINO MOUNTAINS ON MONDAY.
IF HIGHER END RAINFALL AMOUNTS MATERIALIZE ACROSS THE NORTHERN
COACHELLA VALLEY, INCREASED FLOWS ON THE WHITEWATER RIVER COULD
CAUSE FLOODING CONCERNS AT SOME OF THE LOW WATER CROSSINGS. LATEST
RIVER FORECAST ENSEMBLES HAVE AROUND A 22% CHANCE OF THE SAN
DIEGO RIVER REACHING MONITOR STAGE ON MONDAY AND WEDNESDAY.
SNOW LEVELS AT THE ONSET OF PRECIPITATION ARE CURRENTLY FORECAST
AROUND 6500-7000 FT FOR THE SAN BERNARDINO MOUNTAINS AND
INCREASING TO AROUND 7500-800 FT IN SAN DIEGO COUNTY. THIS WILL
REDUCE THE FLASH FLOOD THREAT ON UPPER PORTIONS OF THE BURN SCARS.
THE SNOW LEVEL FALLS TO AROUND 4500-5500 FT MONDAY NIGHT AS
PRECIPITATION TURNS LIGHTER AND MORE SHOWERY. FOR THE FIRST ROUND
OF SNOW MONDAY AND TUESDAY, 5-12 INCHES EXPECTED AT 5500-6500 FT,
12-18 INCHES EXPECTED AT 6500-8000 FT, AND UP TO 33 INCHES ABOVE
8000 FT.
FOR THE 48 HOUR PERIOD OF 4 AM WEDNESDAY TO 4 AM FRIDAY, THE NBM
HAS A 30-50% CHANCE OF 0.50" OR MORE FOR THE COASTS AND VALLEYS, A
40-70% CHANCE IN THE MOUNTAINS, AND A 5-10% CHANCE IN THE DESERTS.
FOR THIS SAME TIME PERIOD, THERE IS AROUND A 25% CHANCE OF AT
LEAST 6" OF SNOW AT THE 5500 FT LEVEL, INCREASING TO AROUND A 40%
CHANCE AT 7000 FT. CHANCES OF ACCUMULATING SNOW (0.1" OR MORE) ARE
AROUND 50% THROUGH THE CAJON PASS AND ALONG HIGHER PORTIONS OF
I-8 NEAR SUNRISE HWY AND TECATE DIVIDE.
