temperatures are running up to 9 degrees warmer this afternoon
than this time yesterday. All in all, it is a great day and
beautiful day to prepare for the next big Pacific storm headed our
way tonight.

This powerful Pacific storm will bring multiple impacts to the
region, but come in waves of rain and wind between tonight and
Tuesday. The first and stronger wave will impact the region tonight
through early Tuesday.

As for the rain, light rain will initially spread across the
region this evening, but intensify as we go through the late night
and early morning hours. TPW imagery shows that the moisture plume
feeding into this first band upwards of 1.2 to 1.4 inches, so
there is plenty of moisture available. Given the moisture content
and the instability for tonight, periods of heavy rain will be
possible late tonight through tomorrow morning. The models have
been speeding up this portion of the system, moving it through
the majority of the Bay Area by 10 am. The exception is Monterey
County, where we will likely be in it a little longer. That said,
the morning commute will be a mess with the high winds, heavy
rain, and likely flooding. Travel is not advised tomorrow morning.
During this time frame, the WPC Excessive Rainfall Outlook paints
the entire forecast area with a moderate risk, which suggests a
40-70% chance of exceeding Flash Flood guidance.

Even though the models are also suggesting a break in the
rainfall tomorrow afternoon, believe showers will continue
through the day. SPC also has the Central Coast in Marginal Risk
for severe weather, as there is instability with strong low level
wind could lead to a brief tornado. The secondary wave will bring
another round of heavy rain to the region Monday night through
Tuesday morning. This secondary system is even more unstable than
the first, with showers and thunderstorms likely continuing after
the mainband of rain. These showers and thunderstorms will be
capable of putting down significant rainfall in a short amount of
time.

Therefore, a Flood Watch remains in effect through 4 pm on
Tuesday. Do expect widespread flooding to occur late tonight and
through Tuesday, with rapid rises along area streams and creeks
and rivers will occur. Several mainstem rivers are also forecast
to go above flood stage as well, and Flood Warnings have started
to be issued. A Flash Flood Watch has also been issued for the
Monterey County burn scars of the River, Colorado, and Dolan
Fires. In coordination with our partners at the USGS, the threat
for widespread shallow landslides is likely, especially along
steep hillslopes during intense precipitation.

As for the winds tonight through Monday morning: Strong winds
will begin to spread across the region between 8 and 10 pm,
strengthening and continuing through the night and early morning
hours, before weakening. Our local wrf as well as the Nam12 show
925 winds increasing to between 60 and 70 kts, with even strong
winds at 850 mbs. Therefore, a High Wind Warning is now in effect
starting at 8 pm this evening. Expect gusts up to 60 mph possible
along the immediate coast and our valley locations. Gusts up to 80
mph will be possible in the higher elevations, and it would not
surprise me if we had some local gusts up to 90 mph in some of the
favored windy spots. Winds will decrease during the morning
hours. That said, winds will increase again Monday night, and more
wind products will likely be needed at the time.

Drier conditions will finally develop for Wednesday and Thursday for
most of the area. However, models are suggesting that a warm
front may clip the region. That said, think the North Bay would be
the region most likely to see some light rain those days. Any
rain would be light, with most areas seeing less than a quarter
inch. However, North Bay could see between 1 to 2 additional
inches with the coastal mountains seeing up to 3. Another weak
system will then move into the region on Friday. Followed closed
by another more significant system for the weekend. At this time,
there are still some model differences, but given the fact that
most areas will not have had sufficient time to dry out, flood
watches will likely be needed again. Palmer

Some of the more notable river and stream forecasts that are
expected to reach at least minor flood stage include, but not
limited to, the Russian River at Guerneville, Alameda Creek near
Niles, Coyote Creek above HWY 237 at Milpitas, and the Big Sur
River near Big Sur. More notable is the San Lorenzo River at Big
Trees, which is forecast to reach major flood stage Monday
evening.
