The storm is subsiding in Santa Clara County and moving east. Street flooding has occurred and all drivers are cautioned to take extra care on your drive home. Stream flows in local creeks were actively monitored all day and none have reached capacity or experienced flooding.

The water district is working diligently to keep all of its sandbag distribution areas stocked with sand and empty bags. Additional filled sandbags will be delivered Friday, Dec. 12, to Palo Alto (3,600), Alviso (1,800), Morgan Hill (3,600), and City of San Jose Central Service Yard (1,800). Sand bag distribution sites are open 24-hours for the public. Locations can be accessed at: http://www.valleywater.org/services/sandbagsites.aspx.

The water district will have sand on continuous order and is coordinating with local agency public works departments during the course of the storm.

The public is asked to submit any information about downed trees in streams or other threats of stream flooding to Access Valley Water: www.valleywater.org

Many thanks to the California Conservation Corps for their assistance in filling sandbags during this storm.

This is the final update for the day. While storm conditions are not expected to pose a concern tomorrow, we will provide another update if needed.


1:30 p.m.

The storm continues to hit Santa Clara County. At this point, street flooding has been observed but no flooding has occurred on local streams or creeks.

Because of the lower elevation of the Alviso community, it is prone to flooding. The City of San Jose is operating a pump station to keep rain water from inundating local streets. The water district is providing additional pumping resources to reduce the risk of potential for street flooding.

Flows in Ross, West Little Llagas, San Francisquito, and Upper Penitencia/Berryessa creeks are being actively monitored as further bands of rain come through. There remains the potential for flooding along Ross Creek in West San Jose and West Little Llagas in Morgan Hill. Water district crews are on location.

Residents are reminded to not walk through moving water. Six inches of moving water can make you fall. Also, do not drive into flooded areas. If floodwaters rise around your car, abandon the car and move to higher ground. You and the vehicle
can be quickly swept away. A foot of water will float many vehicles. Two feet of rushing water can carry away most vehicles, including SUVs and pick-ups.
