El Niño conditions are characterized by unusually warm ocean temperatures in the Equatorial Pacific. Weather experts have been closely monitoring the increasingly warm temperatures since early 2015, giving them strong confidence to predict a strong El Niño.
El Niño conditions do not “cause” individual storms but rather influence their frequency and characteristics. This El Niño event is forecast to rival previous strong El Niño events, such as 1982/83 and 1997/98.
What does this mean for San Diego?
For more information on El Niño conditions, visit the National Weather Service El Niño Theme Page.
El Niño can bring increased rainfall across Southern California, and in San Diego, this could increase the potential for flooding, mud slides and debris flow.

How to Determine if There are Public Drainage Facilities on Your Property
Flood Control Webcams
|The San Diego County Flood Control District maintains several webcams at selected low water crossings throughout the county. You can view streaming video from the cameras to see the current state of the low water crossings.|
The County currently maintains three webcams: the Quarry Road Dip on Spring Valley Creek in Spring Valley, the Sandia Creek Road Dip on the Santa Margarita River in Fallbrook, and the Country Club Road Dip on Escondido Creek in Harmony Grove.
Sandbags help to divert or redirect water, mud and debris from your property and help prevent soil erosion.
Free sand and sandbags are available to residents and business throughout San Diego County at the following locations:
Sandbags are also available at these retail vendors.
For more information on flood debris and erosion control, view the Homeowner’s Guide for Flood, Debris, and Erosion Control.
Sandbags can help protect your property from major damage, but sandbags will not seal out water, which is why it is important to make sure your property is financially covered.

Standard homeowners insurance does not cover flooding. It is important to have protection from the floods associated with heavy rains here in San Diego County. The National Flood Insurance Program (NFIP) is available to property owners to financially protect themselves.
Understanding Your Flood Risk
|FEMA’s Flood Map Service Center is the official public source for flood hazard information. There, you can find official flood maps and other resources to get a better understanding of your flood risk.|
Residents in recent wildfire burn areas should be aware of the increased potential for mud slides, debris flow, and severe flooding. The San Diego County Adverse Weather Map displays the 100-year Floodplain, recent fire burn areas, and weather alerts.
How Much Would a Flood Cost?
It only takes a few inches of water to cause major damage to your home or business and its contents. Learn more about the cost of flooding.
