NWS Rules Out Tornado in San Clemente After Storm Damage

Key points

• NWS San Diego dispatched a team to investigate potential tornado damage at the San Clemente Golf Course on October 22.
• Investigators concluded the event was straight-line winds, not a tornado, despite reports of a tree being cut in half.
• Witnesses described a 30-foot path of destruction and a whipping sound lasting 15 to 25 seconds.
• The storm brought heavy rain, with 1.5 to 3 inches expected in parts of Los Angeles County.
• Flash flood warnings were issued for eastern Los Angeles County and the Malibu coast.

Background

This weather event follows a period of extreme conditions in Southern California. In late September, Tropical Storm Rachel brought heavy rain to San Diego. In mid-October, Santa Ana winds fueled wildfires, including the Norte Fire in San Clemente, which destroyed homes and left burn scars vulnerable to runoff. The current storm is part of a wetter-than-normal season influenced by El Niño, which meteorologists warned could increase tornado risks in the region.

How outlets are covering it

California Post initially reported a suspected tornado touchdown, citing NWS investigations. NBC4 Los Angeles clarified that the NWS determined the event was straight-line winds, not a tornado, while noting a separate weak tornado warning for the San Gabriel Valley. Victor Valley News Group reported unrelated swirling winds in Victorville, describing them as possible dust devils or gustnados, highlighting the widespread but varied nature of the storm's impact across the state.

Why it matters

The distinction between tornadoes and straight-line winds is critical for insurance claims, infrastructure planning, and public safety protocols. While tornadoes are rare in Southern California, the increasing frequency of severe storms due to El Niño conditions necessitates updated risk assessments for coastal and urban areas. The event also underscores the vulnerability of recent wildfire burn scars to flash floods and debris flows.

What to watch

The NWS will continue monitoring for scattered showers and isolated thunderstorms through the night. Forecasters expect the most intense weather to have passed by early Thursday afternoon, but residents in affected areas should remain cautious of potential flooding and wind damage. Cleanup efforts will likely focus on downed trees and debris in San Clemente and surrounding communities.
