Flash Flood Watch

Statement as of 2:01 PM PST on February 25, 2017

Expires 7:00 AM EST on March 03, 2017


... Flash Flood Watch remains in effect through late Thursday
night...

The Flash Flood Watch continues for

* a portion of northern California... including the following
areas... Carquinez Strait and Delta and northern San Joaquin
Valley.

* Through late Thursday night

* Don Pedro and other local dams are making large Reservoir
releases that are raising river levels along the lower San
Joaquin River north of Grayson into the South Delta. These
elevated levels are causing flooding in the low-lying areas
along the river and increasing concerns on the levees in the
area.

* Previously identified concern areas on local levees will
continue to see increased river levels. As a precaution, San
Joaquin County officials and the National Weather Service are
encouraging local residents to be prepared to take action in
the event that levee conditions were to deteriorate.

Precautionary/preparedness actions...

A Flash Flood Watch associated with levees means that there are
conditions that could affect levee stability. If levee conditions
were to deteriorate into a failure, it could lead to flash
flooding and the rapid arrival of flood waters within the area
protected by the levee. People in the area of the Flash Flood
Watch should monitor NOAA Weather Radio and other news outlets
for updates to this situation. Be prepared to quickly evacuate
should a Flash Flood Warning be issued.
