Watches & Warnings

High Wind Watch
Issued: 2:17 PM PST Nov. 23, 2017 – National Weather Service

... High wind watch remains in effect from Saturday morning
through Sunday afternoon...

* timing: winds will increase Saturday afternoon and become strong
and gusty Saturday night through Sunday afternoon.

* Winds: south to southwest 25 to 35 mph with gusts to 60 mph
possible. Wind prone areas may see gusts up to 70 mph, with
Sierra ridge gusts up to 100 mph.

* Impacts: strong cross winds and travel restrictions are likely
to impact high profile vehicles especially along Highway 395 and
Interstate 580. Aviation impacts are expected for area airports
Saturday afternoon through Sunday. Localized damage to trees
and fences may occur along with possible power outages.

Precautionary/preparedness actions...

Now is the time to secure loose outdoor items such as patio
furniture, Holiday decorations, and trash cans before winds
increase which could blow these items away. The best thing to do
is prepare ahead of time by making sure you have extra food and
water on hand, flashlights with spare batteries and/or candles in
the event of a power outage.





Special Statement
Issued: 2:16 PM PST Nov. 23, 2017 – National Weather Service

... Strong winds this weekend with snow over the passes by late
Sunday...

A potent Pacific storm will move inland this weekend and bring
Rain, Mountain snow and gusty winds. The winds will begin Saturday
afternoon and continue through Sunday night. Precipitation will
begin as rain, even at the passes, as snow levels start high.
Snow levels will begin to fall Sunday with snow over the passes
possible by sunset Sunday. Expect Holiday weekend travel impacts
due to winds and snow over the passes. Some details follow:

* winds: strong, gusty southwest winds are expected this weekend.
Winds will be breezy on Saturday and then increase significantly
overnight into Sunday afternoon. While it is too early to
estimate peak gusts, gusts of 60 mph or more are possible along
portions of the 395 corridor and Sierra ridge gusts will likely
exceed 100 mph.

* Precipitation: light rain is likely over the mountains by
Saturday evening north of I-80, gradually spread southward into
Sunday evening. Snow levels will also gradually fall during this
time before crashing Sunday night as a strong cold front moves
through. The precipitation will end Monday morning behind the
front.

* Snow levels: starting at near 9000 feet Saturday afternoon. They
will fall to 5500 feet for Lassen County, 7000 feet for the
Tahoe basin, and 8000 feet for Mono County by late Sunday
afternoon. Snow levels will crash Sunday night and fall to near
the Lower Valley floors as the precipitation ends. While it is
too early to predict snowfall amounts, moderate accumulations
are likely for the Sierra passes with light accumulations
possible as low as 4500 feet. Be prepared for major travel
delays over Sierra passes due to slick and snow-covered roads.
