Rare October Storm Causes Roof Collapses, Flooding, and Road Hazards in Southern California

Storm Impacts Across Southern California

• 🌧️ A rare October storm brought significant rainfall to Southern California, causing widespread issues including roof collapses, flooded roads, and mudslides.
• ⚠️ The storm unleashed downpours across most of the region, with some areas receiving over an inch of rain in a short period.

Roof Collapse and Studio Damage

• 🏠 In Sun Valley, a roof collapse occurred at a studio, with powerful water pouring through a sidewall and destroying props for sci-fi films.
• 💥 The owner described the event as a waterfall coming from the roof, completely caving in a sidewall and leaving a significant mess.
• ✅ Fortunately, no injuries were reported at the studio, which was considered a lucky outcome.

Road Hazards and Traffic Disruptions

• 🚗 Multiple big rig crashes and other vehicle accidents were reported on freeways, including the I-5 and the 91 freeway, causing significant traffic snarls.
• 🌊 Flooded streets and highways, such as the I-5 at Lancer and near the 118, forced drivers to navigate through water or around barricades.
• ⚠️ A small mudslide on the 110 freeway in Highland Park also slowed traffic and required lane closures for cleanup.

Rainfall Totals and Weather Outlook

• 📊 Downtown LA received about 1.24 inches of rain, significantly above the typical monthly average for October.
• 📈 Woodland Hills recorded over three and a quarter inches of rain in the last 12 hours, with other areas like Burbank and Beverly Hills also seeing substantial accumulation.
• 🌬️ While the main storm system moved east, spotty light showers and wintry mixes were still occurring in some northern and eastern areas, with wind and winter weather advisories in place.

Burn Scar Areas and Mudslide Concerns

• ⛰️ Areas like Altadena and the Palisades, still scarred from recent wildfires, faced concerns about mud and debris flows.
• 🏞️ The Rubio wash debris basin in Altadena appeared to have done its job, with minimal debris flow reported, partly due to pre-storm cleanup efforts.
• ⚠️ Despite the storm not being as destructive as feared in burn scar areas, officials remained vigilant due to saturated hillsides, with concerns about potential mud and debris flows in the coming days.
• 🌊 Residents in Malibu and the Palisades also experienced heavy rain, but PCH remained open this time, unlike in previous storms, and no major mudslides were reported in those vulnerable areas.
