...PREPARE NOW FOR ANOTHER MAJOR STORM WEDNESDAY AND THURSDAY.
IMPACTS WILL START LATE TUESDAY NIGHT...

Prepare Ahead of the Storm: Utilize the next 48 hours wisely

- Existing Snow: Do as much cleanup from weekend storm as
possible. Reduce snow load on structures. Clear snow from drains
and gutters.
- Evaluate your "back up plans" for travel over the Sierra
(snow/rain) and wind prone valleys (wind) Wednesday-Thursday.
- Winds Incoming: secure loose objects, construction equipment,
and garbage cans ahead of the strong winds.

For the Mountain Communities and the Sierra (above 6000 feet)

- Plan for major delays in mountain travel midweek. High
confidence for travel impacts from heavy rains and/or heavy snow
for Wednesday and Thursday.

- MORE SNOW: Areas above 8500 feet should plan for a major
snowstorm, with areas of low visibility and increasing concerns
with snow loading on buildings.

- HEAVY RAIN or HEAVY WET SNOW? Areas below 8500 feet, the snow
level forecast is highly uncertain with scenarios ranging from
heavy rain to heavy wet snow. Plan for both and be sure to clear
any and all drainage areas of snow. Have a plan in place to mitigate
urban flooding concerns due to heavy rains.

- Strong winds are a safe bet for all areas in the mountains.
Primary travel impacts due to winds will range from issues for
high profile vehicles, rough air travel for flying, and impacts
to the higher elevation ski areas.


For the Foothills and Valleys (6000 feet and below):

- HEAVY RAIN or HEAVY WET SNOW? Snow level forecasts have been
widely varied with this storm, but a heavy rain scenario is
fairly certain. Rises on streams and terminal lakes are
possible. Poor drainage flooding is also likely for areas that
typically experience urban flooding during heavy rains,
especially areas where snow is damming up drains and culverts.

- Strong winds will result in high profile vehicle restrictions as
well as rough conditions for air travel. Damage to trees and
power lines is also possible along with minor structural damage.
Area lakes will also be contending with choppy conditions and
significant wave heights. See the High Wind Watch for more
details.

* WHAT...Heavy snow possible above 7000 feet. Total snow
accumulations of 6 to 10 inches for Truckee and South Lake,

Potential snow accumulations below 8000 feet would be much less
if this occurs. If snow levels are slow to rise, heavy
accumulations may occur at Lake Tahoe level and along the 395
corridor in Mono County.

* ADDITIONAL DETAILS...Travel could be very difficult to
impossible. The hazardous conditions could impact the morning
or evening commute. Very strong winds could cause extensive
tree damage.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Now is the time to prepare an emergency kit for your home and
car. If traveling consider alternate plans, remember to carry
tire chains, extra food, water and clothing. Once the storm

...FLOOD WATCH IN EFFECT FROM LATE TUESDAY NIGHT THROUGH THURSDAY
MORNING BELOW 5000 FEET...

The National Weather Service in Hanford has issued a

* Flood Watch for a portion of central California, including the
following areas, Mariposa, Madera, and Fresno County
Foothills, Sierra Nevada from Yosemite to Kings Canyon, Tulare
County Foothills, and Tulare County Mountains.

* From late Tuesday night through Thursday morning

* Heavy rain will move in late Tuesday night and continue through
late Wednesday night. Rain on top of snow will potentially
create flooding concerns in areas below 5000 feet in the Sierra.

* Rivers and streams will rise on Wednesday as rain increases
through the day. Street flooding and mudslides are also possible
in foothill communities.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

A Flood Watch means there is a potential for flooding based on
current forecasts.

You should monitor later forecasts and be alert for possible
Flood Warnings. Those living in areas prone to flooding should be
prepared to take action should flooding develop.
