...THE FLOOD ADVISORY FOR A DAM FLOODGATE RELEASE REMAINS IN EFFECT
UNTIL 345 PM PST SUNDAY FOR SOUTHEASTERN SANTA CLARA AND NORTHWESTERN
SAN BENITO COUNTIES...

* 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 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.

* 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.

...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 426 AM PST, a combination of excessive rainfall over the past few
weeks, in addition to continued rainfall over recent days, has led
to elevated river/creek levels and damaged levees along the Pacheco
Creek. Flooding is actively occurring along the Pacheco Creek near
Lovers Lane and San Felipe Road 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. 

Additional rainfall anticipated late tonight into Sunday morning
will likely result in additional rises on the Pacheco Creek and
exacerbate flooding in the warned 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.
