Areal Flood Watch
Issued: 4:20 AM PST Feb. 20, 2017 – National Weather Service

... Flood Watch remains in effect through Tuesday morning...

The Flood Watch continues 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.

* Through Tuesday morning

* a strong atmospheric river will bring heavy rain with high snow
levels. Moderate to heavy rain along with snow melt below 7000
feet will contribute to increasing flows on rivers and streams
with an enhanced flood potential 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. The upper reaches of the Truckee and Carson rivers are
forecast to rise to near monitor stage tonight into Tuesday, but
at this time are expected to remain below flood stage.

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.
