Flooding poses a serious risk to life, property and public health and safety and could cripple the state’s economy. Substantially populated counties with vulnerable populations are in flood-prone areas of southern California, the San Francisco Bay Area, the Delta region and the Central Valley. In addition, many urban and rural areas are not protected by levees and are subject to recurring, seasonal flooding by local rivers or streams.
Winter storms in California can be deadly, causing flooding, flash floods, high coastal surf, mudslides, snowstorms and avalanches. Here’s a list of tips to follow during the different stages of a flood as it upgrades in severity from watch to warning.Winter Weather & Flood Preparedness Brochure
If you believe flash flooding has begun, evacuate immediately as you may have only seconds to escape. Move to higher ground and away from rivers, streams, creeks and storm drains. Do not drive around barricades. These are placed to keep you out of harm's way. If your car stalls in rapidly rising waters, abandon it immediately and climb to higher ground.
Wherever you live or travel, you should be aware of the dangers of winter storms and be prepared to cope with one. For more information on the history of flooding in your area, and how you and your family can prepare for winter, call your city or county Office of Emergency Services, or the nearest office of the National Weather Service.
