Watches & Warnings

Areal Flood Warning
Issued: 3:56 PM PST Jan. 20, 2017 – National Weather Service

The National Weather Service in the San Francisco Bay area has issued
a

* Flood Warning for urban areas and small streams in...
southeastern Santa Clara County in northern California...
northwestern San Benito County in central California...

* until 345 PM PST Monday

* at 344 PM PST, a combination of excessive rainfall over the past
weeks... in addition to continued rainfall over recent days... has
led to elevated river levels and damaged levees along the Pacheco
creek. Flooding is actively occurring along the Pacheco creek
near Lovers Lane and San Felipe Rd north of Hollister. Flooding
may also be possible or occurring on soap/San Felipe Lake...
Frazier Lake... and other smaller tributaries in the impacted
area.


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: 3:46 AM PST Jan. 21, 2017 – National Weather Service

... Flash Flood Watch remains in effect from late tonight through
Sunday afternoon...

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.

* From late tonight through Sunday afternoon

* periods of heavy rain on already saturated soils will impact
the region from late tonight through Sunday afternoon.
Additional rainfall amounts from 0.75 to 1.5 inches are possible
at lower elevations with 2 to 5 inches across the North Bay and
coastal slopes.

* 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.




351 PM PST Fri Jan 20 2017

The National Weather Service in the San Francisco Bay area has issued
a

* 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 Sunday

* 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 that are anticipated in response to
forecast rainfall 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 an additional 1-2" of rainfall this
weekend in the Pacheco creek watershed that feeds the Reservoir.
Development of Post-frontal convective thunderstorms over the
watershed could increase local precipitation totals over the
weekend. 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.

* At this time (friday), there is no flooding occurring. 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 hazard 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 to local radio and
television, 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.

and/or location is still uncertain. It is intended to provide
additional lead time for mariners who may wish to consider
altering their plans.
