Fire Weather Planning Forecast For Southwestern California

249 PM PDT Mon Mar 10 2025

...PERIODS OF RAIN AND MOUNTAIN SNOW TUESDAY THROUGH THURSDAY...

...FLOOD WATCH IN EFFECT WEDNESDAY NIGHT INTO THURSDAY FOR
MANY AREAS SOUTH OF POINT CONCEPTION, MAINLY FOCUSED ON RECENT
BURN SCARS WITH THE POTENTIAL FOR DEBRIS FLOWS...


.DISCUSSION...
Dry weather today, then a cold upper level low pressure system will
likely bring some rain to areas south of Point Conception on Tuesday,
especially in Los Angeles county where there will also be a 5-10 percent
chance of thunderstorms. Most areas  are expected to see less than
0.50 inches of rain, however there could be isolated higher amounts
near heavier showers or thunderstorms in Los Angeles County. Peak
rainfall rates could be up to 0.33 inches per hour across Los
Angeles County. Due to the fast moving nature of these storms,
0.33 inches may occur in time frames as little as 15 to 30 minutes.

A stronger storm system is then expected to impact the region
Wednesday into Thursday. On Wednesday, there will likely be
light to moderate pre-frontal rainfall, heaviest in orographically
favored coastal slopes and foothills. A fast moving and strong
cold front will then sweep across the region on Wednesday night,
brining the potential for 3 to 4 hours of moderate to heavy rainfall
and a 10-20 percent chance of thunderstorms. Behind the front,
there will be cold and unstable air that will bring the threat of
heavy showers and a slight chance of thunderstorms into Thursday morning.

Storm totals for Wednesday into Thursday are expected to range from
1 to 2 inches for coasts and valleys, and 2 to 4 inches for foothills
and mountains. Peak rainfall rates are most likely expected to
impact the region on Wednesday night, when peak rates of 0.50 to
0.75 inches per hour will be common. There is a 10-20 percent chance
of rates locally reaching 1.00 inch per hour, mainly near any
thunderstorms pr orographically favored coastal slopes. This threat
of higher intensity rainfall has resulted in the Flood Watch issuance
for many areas south of Point Conception, mainly focused on recent
burn scars. In addition, the high intensity rainfall could bring
rock and mudslides, especially near higher terrain, roadway
flooding, and swift water rescues in rivers and streams.

In addition, there will likely be significant snow across the local
mountains for the Wednesday into Thursday storm system, with 1 to
2 feet of snow likely for elevations above 6000 feet. Snow levels
are expected to lower rapidly late Wednesday night into Thursday
morning , falling as low as 3000 feet.  As a result, there is
the potential for accumulating snow and ice on low elevation passes
such as Interstate 5 near the Grapevine, Highway 14 from Agua Dulce
to Palmdale, Highway 33 north of Ojai, and upper portions of Highway
154 through Santa Barbara County.
