The National Weather Service (NWS) issued a Severe Thunderstorm Watch for portions of Southern California, including the Los Angeles and San Diego metropolitan areas, effective from 10:46 PM CDT on October 13th, 2025. The watch, designated as MD 2145, indicates that conditions are favorable for severe thunderstorms to develop in the specified regions. The Severe Storms Prediction Center (SPC) issued the watch via their online product, with the NWS utilizing their official X account to disseminate the information. The announcement was made during the early hours of the current reporting window, at 11:46 PM CDT on October 13th. This severe thunderstorm watch comes as a previous Flood Advisory had been issued for inland Orange County and the San Bernardino Mountains due to moderate to heavy rainfall, according to NWS San Diego. That advisory had urged residents to "Turn Around Don't Drown" due to potential fast-moving water hazards.
