Special Statement
Issued: 4:09 AM PST Nov. 21, 2018 – National Weather Service

... Major change to winter weather today into the Holiday
weekend...

A major change in the weather pattern is coming to norcal starting
today. A series of winter like storms will plow through norcal
bringing rain, winds and mountain snow to the region. The first
system will arrive later today pushing through the north state
tonight. Another system will move though late Thursday and
Thursday night with one last system pushing through on Friday and
Saturday.

Snowfall over the Sierra, debris flow over the recent norcal
fires and periods of strong wind are major concerns with these
weather systems and hazard watches and warnings have been issued
for these impacts.

This change in the weather pattern will bring other impacts as
well. The accumulation of dirt and oils on the roadways will
produce very slick conditions especially early on in this wet
period today and Thursday. Today's evening commute and
Thanksgiving travel period will likely see increased traffic
accidents due to the slick roadways and motorists should use extra
caution. As rainfall accumulates over the Holiday weekend,
ponding water will be possible where storm drains have been
clogged by leaves and other debris.

Use extra care while traveling today and this Holiday weekend as
many weather related hazards will be present that have not been a
concern for the last several months.

Conditions will begin to improve on Saturday with a return to
drier weather expected early next week.
