Special Statement, Air Quality Alert
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.

1224 PM PST Tue Nov 20 2018

The San Joaquin Valley air pollution control district has
extended the air quality alert on November 20, 2018, due to smoke
impacts from surrounding wildfires for San Joaquin, Stanislaus,
Merced, Madera, Fresno, Kings, Tulare, and valley portion of Kern
counties.

Wildfire smoke still impacts the San Joaquin Valley, causing
unhealthy conditions. An approaching low pressure system will
bring some improvement in air quality to the district tomorrow.
The timing of this system could cause this alert to be extended
for the central and southern counties of the valley.

Exposure to particle pollution can cause serious health problems,
aggravate lung disease, cause asthma attacks and acute
bronchitis, and increase risk of respiratory infections.

Residents are advised to use caution as conditions warrant.
People with heart or lung diseases should follow their doctor's
advice for dealing with episodes of unhealthy air quality.

Additionally, older adults and children should avoid prolonged
exposure, strenuous activities or heavy exertion, as conditions
dictate.

For additional information, call your local San Joaquin Valley
air district office. Modesto 209-557-6400, Fresno 559-230-6000,
Bakersfield 661-392-5500

Residents can also follow air quality conditions by downloading
the free valley air app, available in the apple store or google
play.

Issued: 3:32 AM PST Nov. 21, 2018 – National Weather Service

... Fire Weather Watch in effect from Friday morning through
Friday evening for strong and gusty winds for the deserts of
eastern Lassen County into northern Washoe County... the eastern
Sierra... and much of western Nevada...

The National Weather Service in Reno has issued a Fire Weather
Watch for strong and gusty winds, which is in effect from Friday
morning through Friday evening.

* Affected area... fire zone 270 Surprise Valley California, fire
zone 273 Mono and eastern alpine counties, fire zone 278
eastern Lassen County, fire zone 450 western Nevada Sierra
front, fire zone 453 west central Nevada basin and range, fire
zone 458 northern Washoe County and fire zone 459 Mineral and
southern Lyon counties.

* Winds... southwest to west 20 to 35 mph with gusts 50 to 70 mph.
Wind prone locations could potentially see even stronger gusts.
Lighter winds are anticipated for Mineral County with southwest
winds 15 to 20 mph and gusts 35 to 40 mph.

* Humidity... 25 to 35 percent.

* Duration... 4 to 8 hours.

* Impacts... the anticipated strong and gusty winds can cause fire
to rapidly grow in size and intensity before first responders
can contain them.

* This watch will be dependent on how much rain and snow falls on
Wednesday into Thursday morning. If widespread enough wetting
rains fall, it will mitigate the fire danger.

Precautionary/preparedness actions...
