inches of snow will accumulate between 4000 and 5000 feet. The
higher snowfall totals will generally be confined to the southern
mountains (Riverside and San Diego County mountains) today and
tonight. While the San Bernardino Mountains will get some
appreciable snow amounts from this first system, the second system
Friday and Saturday is expected to bring even more snow for them.
A second storm system will drop south into California Friday and
Saturday, bringing additional rounds of precipitation and mountain
snow. As the system drops south into Southern California, it is
expected to tap into weak atmospheric river moisture, which will
increase the amount of rain and mountain snow we receive.
Integrated Water Vapor values are looking to peak Friday night
through Saturday morning, which is when we are expecting the
heaviest rainfall at lower elevations. Precipitation from this
system will be widespread and heavy at times. Please see the
hydrology section below for more details on the precipitation
amounts and timing.
Heavy snow and gusty winds will create dangerous conditions in
the mountains through this weekend. Snowfall is expected on all
of the mountain ranges with the highest accumulations expected in
the San Bernardino and portions of the Riverside County mountains.
Top forecast snowfall totals of 4 to up to 7 feet on the highest
peaks.
Winds in the mountains and deserts are also expected to be strong
with this system, especially on Friday ahead of the main cold
front. The combination of very heavy snow, low visibilities from
snow, blowing snow, and fog, and strong gusty south winds,
blizzard conditions are expected at times in the mountains.
Precipitation looks to taper off later on Saturday, with Sunday
currently expected to be a mostly dry day. There is still some
spread in the ensembles on exactly when the rainfall is expected
to end, so this could change in the coming days.
In short, this will be a highly impactful storm in which we have
not experienced in years. Feet of snow will fall in the mountains,
and there will be flooding concerns at lower elevations. Please
please avoid all travel in the mountains through the weekend. If
you're out and about at lower elevations, take it slow driving,
and give yourself more space between the cars in front of you. Be
safe everyone!

.HYDROLOGY...
Showers will continue throughout the day today. A few tenths of
an inch will accumulate at lower elevations, and around 1 inch
(liquid equivalent) is expected in the mountains through tonight.
Rainfall will become more widespread and heavy on Friday into
Saturday as the second system pushes south, tapping into
atmospheric river moisture. The heaviest rainfall will be
associated with the cold front, which is expected to pass through
late Friday night through Saturday morning.
Forecast rainfall totals through Saturday:
San Diego County coast and valleys: 2 to 3 inches
Orange County coast and inland: 3 to 4 inches

action (monitor) stage on Saturday, peaking around 10 to 11 feet.
These values are fairly close to flood stage, so the forecast
could change as we get closer to the event.
