Watches & Warnings

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.

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.

... Major change to winter weather forecast for the Holiday
weekend...

A major change in the weather pattern is coming to norcal this
week impacting Holiday travel. A series of winter like storms
will plow through norcal bringing rain and mountain snow to the
region. The first system is set to arrive late Tuesday night
pushing through the north state Wednesday and Wednesday night.
Another system will move though late Thursday and Thursday night
with one last system pushing through on Friday.

Snowfall over the Sierra and debris flow over the recent norcal
fires are a major concern with these weather systems and hazard
watches 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

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. In addition to the rainfall,
the weather system passing through norcal late Thursday will bring
gusty south winds. The northern Sacramento Valley could see wind
gusts up to 40 or 45 mph with gusts to over 60 mph over the higher
Sierra. Downed tree limbs, blowing objects, and difficult driving
will be a concern during this late Thursday through Friday time
period. Use extra care while traveling 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 Sunday with a return to drier
weather expected early next week.
