Carquinez Strait and Delta-Northern San Joaquin Valley-
1226 PM PST Fri Feb 24 2017

...FLASH FLOOD WATCH NOW IN EFFECT THROUGH LATE THURSDAY NIGHT...

The Flash Flood Watch is now in effect 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.

...Two weak but cold weather systems to bring low elevation snow
to Northern California...

A couple of relatively weak weather systems are forecast to drop
southward through northern California over the next few days. The
first will move through from north to south late today and
Saturday. The second late Sunday through Monday. Although neither
of these systems are particularly strong, they will contain cold
air producing very low snow levels compared to the warmer storms
of the last several weeks.

Snow levels with the first system could go as low as 1000 feet
over the northern mountains to 2500 feet over the west slopes of
the Sierra. This would bring snow down into the foothills. The
second system will be only slightly warmer with expected snow
levels 1500 feet over the northern mountains to around 3000 feet
Sierra West slopes.

Snowfall amounts with the first system are forecast to range from
2-3 inches over interstate 5 in Shasta county to only 1 or 2
inches over the Sierra passes.

Snowfall amounts with the second system will be a little more
ranging from 3-4 inches over interstate 5 in Shasta county to 4-6
inches over the Sierra passes.

Be prepared if traveling over the mountains over the next several
days. Although snow amounts will not be large, slippery or snow
covered roads are likely and chain controls may be needed with
snow levels lower than experienced over the last several weeks.
