...FLOOD WATCH IN EFFECT FROM MONDAY AFTERNOON THROUGH MONDAY
EVENING...

* WHAT...Flash flooding caused by excessive rainfall is possible.

* WHERE...Portions of California and Nevada, including the following
areas, in California, Greater Lake Tahoe Area, Lassen-Eastern
Plumas-Eastern Sierra Counties, Mono County and Surprise Valley
California. In Nevada, Greater Lake Tahoe Area, Greater
Reno-Carson City-Minden Area and Northern Washoe County.

* WHEN...From Monday afternoon through Monday evening.

* IMPACTS...Excessive runoff may result in flooding of rivers,
creeks, streams, and other low-lying and flood-prone locations.
Area creeks and streams are running high and could flood with
heavy rain. Extensive street flooding is also possible in
urbanized locations.

* ADDITIONAL DETAILS...
- Slow moving thunderstorms will produce areas of heavy
rainfall. Soils are already saturated with creeks, streams,
and rivers running full due to ongoing snowmelt. It will not
take as much rain to cause excessive runoff. Also, heavy
rainfall may lead to flash flooding and debris flows near
burn scars.

...SHOWER AND THUNDERSTORM CHANCES THROUGH MEMORIAL DAY...

* Scattered to numerous showers and thunderstorms will continue
each afternoon through Memorial Day. Storms will be capable of
producing frequent cloud to ground lightning, gusty outflow
winds, small hail, and heavy rainfall.

* With an influx of people enjoying the outdoors this weekend, it
is important that individuals have a way to quickly seek shelter
in the event that a thunderstorm approaches your area. If a
sturdy building is not immediately available, a hard-top vehicle
with the windows rolled up can offer good protection from
lightning. If you plan on doing activities that will leave you
vulnerable to the elements such as hiking, consider doing the
bulk of those activities in the morning hours before
afternoon/evening thunderstorms develop.

* With streams and even mainstem rivers already flowing fast and
cold, it is still advised to avoid swimming in many areas. Keep
in mind that daily showers/thunderstorms will inherently come
with the threat of flash flooding. Have a way to receive weather
alerts, and get to higher ground immediately if a river or
stream you are near begins to rise quickly, if you see debris
floating in the water, or the water suddenly becomes muddy.
