City of Chula Vista
Home MenuSevere Winter Weather
Severe winter weather in Chula Vista may be considered an infrequent occurrence due to the mild coastal climate, but the city can occasionally experience the effects of winter storms, especially during strong El Niño years. These can bring periods of heavy rain, gusty winds, and cooler-than-average temperatures. Urban flooding is the primary concern during intense winter storms, especially low-lying areas and areas adjacent to the natural drainages and flood plains. Residents are encouraged to stay informed through local weather alerts and be prepared for temporary disruptions during such events.

Winter Storm Safety Tips
- Turn Around Don't Drown®
- Avoid walking or driving through flood waters. Just 6 inches of moving water can knock you down, and 12 inches of moving water can sweep your vehicle away.
- Headlights on, Wipers on!
- California Vehicle Code (CVC) Section 24400 mandates that headlights be turned on when wipers are in continuous use due to inclement weather. Headlights improve your ability to see the road, obstacles, and pedestrians — especially in low-light or stormy conditions, and headlights make your vehicle more visible to other drivers, cyclists, and pedestrians—helping prevent collisions.
Sandbags
During significant rain or storm events, sandbags may be made available at the City’s Public Works Operations Yard at 1800 Maxwell Road.
When sandbag distribution is activated, the City will post updates on social media with the availability, dates, and distribution details.
Storm Drains
In the event of flooding due to a blockage of the storm drain system, residents/business owners may call the Public Works Department at (619)-397-6000 during normal business hours, Monday - Thursday, 6:30am - 4:00pm and Fridays, 6:30am - 3:00pm. The Public Works offices are closed every other Friday.
In cases of flooding after normal work hours, weekends or holidays, contact the Chula Vista Police Department at (619)-691-5151.
