San Bernardino County warns of sudden summer storms, higher mudslide risk in burn areas

San Bernardino County issued a public safety announcement warning that summer storms can develop quickly and produce sudden, intense downpours that raise the risk of flash floods, mudslides and debris flows, especially in areas recently affected by wildfires.

The county said microbursts — sudden, localized downpours — can dump heavy rain in a single spot in minutes. In burn areas where vegetation has been removed and soil can repel water, even modest rainfall can trigger rapid runoff and unstable flows of mud and debris.

The advisory urged residents to take warnings seriously and to follow posted evacuation routes. Listeners were directed to prepare.sbcounty.gov for more information about mudslides, debris flow and safety steps.

The announcement focused on hazard awareness and evacuation guidance; no regulatory actions or formal votes were discussed in the recorded message.
