Watches & Warnings

Areal Flood Warning
Issued: 10:13 PM PST Jan. 22, 2017 – National Weather Service

... A Flood Warning for urban areas and small streams remains in
effect until 345 PM PST Monday for southeastern Santa Clara and
northwestern San Benito counties...

At 1008 PM PST, Doppler radar and automated rain gauges indicated
moderate rainfall continues over the warned area and Pacheco creek
continues to rise to near flood stage. Run-off from recent rainfall
will likely result in continued rises through late tonight that will
result in additional flooding.

Some locations that will experience flooding include...
northern Hollister, soap/San Felipe Lake, Frazier Lake area and
lover's Lane.

Precautionary/preparedness actions...

Turn around, don't drown when encountering flooded roads. Most flood
deaths occur in vehicles.

In hilly terrain there are hundreds of low water crossings which are
potentially dangerous in heavy rain. Do not attempt to cross flooded
roads. Find an alternate Route.

A Flood Warning means that flooding is imminent or occurring. All
interested parties should take necessary precautions immediately.

Flash Flood Watch, Areal Flood Advisory
Issued: 2:53 AM PST Jan. 23, 2017 – National Weather Service

... Flash Flood Watch remains in effect through this evening...

The Flash Flood Watch continues for

* a portion of western California... including the following
areas... coastal North Bay including Point Reyes National
Seashore... East Bay hills and the Diablo Range... East Bay
interior valleys... mountains of San Benito County and interior
Monterey County including Pinnacles National Monument... North
Bay interior valleys... North Bay mountains... northern Monterey
Bay... northern Salinas valley/Hollister Valley and Carmel
Valley... San Francisco... San Francisco Bay shoreline... San
Francisco peninsula coast... Santa Clara Valley including San
Jose... Santa Cruz Mountains... Santa Lucia mountains and Los
Padres National Forest... southern Monterey Bay and Big Sur
coast and southern Salinas valley/Arroyo Seco and Lake San
Antonio.

* Through this evening.

* Periods of heavy rain on already saturated soils and full
reservoirs will impact the region through this evening.

* The primary impacts will be localized ponding of water on low
lying roadways with poor drainage... rapid rises on streams and
creeks with some likely exceeding bankfull... some river
flooding... and potential rock and mud slides. Recent burn
scars will also be susceptible to debris flows during periods
of intense rainfall.

Precautionary/preparedness actions...

A Flash Flood Watch means that conditions may develop that lead
to flash flooding. Flash flooding is a very dangerous situation.

You should monitor later forecasts and be prepared to take action
should flash flood warnings be issued.





343 PM PST sun Jan 22 2017

The National Weather Service in the San Francisco Bay area has
extended the

* Flood Advisory for...
a dam floodgate release in...
southeastern Santa Clara County in northern California...
northwestern San Benito County in central California...

* until 345 PM PST Monday

* local water district and County emergency management personnel
have indicated that limited portions of the spillway structure for
Pacheco Lake have been compromised from prior storm activity and
spillway releases this winter. Specifically, there is concern that
renewed spillway releases anticipated in response to forecast
rainfall through the remainder of this weekend could cause
additional erosion of the spillway structure, which could lead to
excessive sediment and/or runoff to enter Pacheco creek
downstream. Excessive runoff and sediment could cause or increase
flooding downstream.

* NWS Monterey is forecasting only minor additional accumulations of
of less than a quarter of an inch through Monday in the Pacheco creek
watershed that feeds the Reservoir. Development of Post-frontal
convective thunderstorms through tonight could cause brief heavy rain
and locally higher amounts. Rainfall this weekend will likely be
accompanied by increased releases over the spillway, but it is
currently not expected that additional releases would pose additional
risk to the spillway or downstream areas.

* Engineers from the local water district as well as California
division of safety of dams and California department of water
resources engineers are on-site conducting inspections and
assessing the level of risk posed by current and expected
conditions. County emergency managers are aware of the situation
and are taking appropriate action and following necessary
protocols.

* There is no expectation at this time that a dam breach or failure
would occur. The dam itself is not compromised; it is only the
spillway structure that is under investigation.

* Should the situation worsen and elevate the threat to human life
and property, either prior to or during storm activity this
weekend, a Flash Flood Warning will be issued for affected areas.
Stay tuned to your wireless emergency alerts via cellular phone,
emergency alert system interruptions on local radio and television
stations, NOAA Weather Radio, twitter (@nwsbayarea), facebook
(nwsbayarea), and other local news and notification services
should a Flash Flood Warning be necessary.

Precautionary/preparedness actions...

Turn around, don't drown when encountering flooded roads. Most flood
deaths occur in vehicles.

Be especially cautious at night when it is harder to recognize the
dangers of flooding.
