Southern California is preparing for a string of storms this week that will deliver heavy rain to coastal and basin regions and heavy snow to mountain regions. Heavy rain has been warned by the National Weather Service to increase the danger of flooding and debris flow and hazardous road conditions, especially in burn areas.
What to Expect: Rain and Possible Flooding with Snow
- First is on Monday night with a follow-up and more intense system on Wednesday through Thursday.
2 to two inches of rainfall is to be forecast for valleys and coastal regions and two to four inches for mountains and foothills.

- No flash flood warnings yet by NWS but caution residents to stay alert with particular emphasis on residents in areas prone to debris flow.
National Weather Service Meteorologist [Name] stated that “The strength of mid-week rainfall can lead to flash flooding and is particularly a danger in burn areas that are prone to wildfire. Citizens should prepare for evacuation notices.”
How Does This Storm Compare to Other Years?

- While this has been a dry winter compared to recent winters, collectively these storms add to water reservoirs and winter snowpack for the state.

- Preparing before departure is crucial.
- Get accustomed to local weather forecasts and emergency broadcasts.

- Prepare your home by unclogging your gutters, securing your patio furniture, and stocking up on backup supplies such as flashlights and batteries.
- Obtain sandbags through your local fire stations in areas prone to flooding.
- Keep your emergency evacuation bag prepared in case you are living near a wildfire burn scar.
Emergency spokesman [Name] cautioned for preparedness by stating that “Even in areas that are not flooded, there can be power outages, gridlock and hazardous traveling conditions with heavy rain. A little planning can make a big difference.”
It is going to rain.
- This set of storms should start to dissipate by Friday, but meteorologists are monitoring a system that has the potential to bring additional rain late next week.
