to drive through flooded waters.

Areal Flood Watch

Statement as of 3:26 PM PST on February 18, 2017

Expires 1:00 PM EST on February 21, 2017


... Flood Watch now in effect from late Sunday night through
Tuesday morning...

The Flood Watch is now in effect for

* portions of east central California and western Nevada,
including the following areas, in east central California,
greater Lake Tahoe area. In western Nevada, greater Lake Tahoe
area.

* From late Sunday night through Tuesday morning

* a strong atmospheric river will bring heavy rain with high
snow levels. Moderate to heavy rain and snow melt will
contribute to increasing flows on rivers and streams with an
enhanced flood potential late Sunday night through Tuesday
morning.

* The highest risk of flooding is along creeks, streams, and
poor drainage areas, including the upper Truckee River in
South Lake Tahoe. Rivers such as the Truckee and the east and
West Forks of the Carson will see appreciable rises but at
this time are expected to remain below flood stage.

* There will be an increased risk of rock and mud slides in
steep terrain with potential for Road closures.

Precautionary/preparedness actions...

Small creeks and streams are the most susceptible to flooding.
Excessive rainfall may also generate rock and mud slides in steep
terrain. Persons in the Lake Tahoe area should take action to
clear blocked drains and areas where snow berms would allow water
to collect and damage property. Persons living along small creeks
and streams should monitor the latest weather information at
weather.Gov/Reno and be prepared to take action should flooding
occur.
