A powerful winter storm sweeping across Southern california is easing, but forecasters warn a fresh system could arrive on Christmas Day, bringing more showers and the possibility of thunderstorms.
Officials say this season’s Christmas could be among the wettest in years, with flash floods and mudslides a real threat in burn-scar regions that were stripped of vegetation by wildfires earlier this year.
Rescues, Evacuations and Shelter Efforts
In San Bernardino County, firefighters rescued people stranded in cars as mud and debris rushed along a road serving Wrightwood, a mountain town about 80 miles northeast of Los Angeles. authorities said the number of rescues was not instantly clear, and responders checked homes door to door while ordering shelter-in-place for parts of the area.
an evacuation order was issued for lytle Creek in the same mountainous corridor.
Travis Guenther and his family found themselves cut off when roaring waters washed out the only bridge into their neighborhood. More than a dozen neighbors sheltered at a community center or sought hotel rooms as the floodwaters surged.
Community Response and Ongoing Struggles
Residents described a tense race to secure supplies as roads turned treacherous.In one case, a Facebook post mobilized neighbors who arrived within an hour with bread, vegetables, milk, diapers and other essentials to help families endure the storm.
Local officials noted that the Wrightwood area already faced challenges from a 2024 wildfire that left terrain vulnerable to future flood and debris flows.
Wider Warnings Across the Region
Coastal zones including Malibu remained under flood warnings through Wednesday evening, and broader wind and flood advisories covered much of the Sacramento Valley and the San Francisco Bay Area. Interstate 5 near Burbank Airport also faced closures due to rising water and debris.
The storms stem from multiple atmospheric rivers drawing tropical moisture into California during one of the year’s busiest travel weeks.
Meteorology and Government Response
forecasts indicate many areas could receive four to eight inches of rain this week, with mountain regions seeing even higher totals. Snow persisted with near white-out conditions in parts of the Sierra Nevada, elevating avalanche risk around Lake Tahoe. A winter storm warning remained in effect into Friday morning.
Governor Gavin Newsom declared a state of emergency in six counties to speed up state assistance for storm response. State resources and first responders were deployed to coastal and Southern California counties, with the California National Guard placed on standby.
Authorities also confirmed a weather-related crash south of Sacramento that claimed the life of a Sacramento sheriff’s deputy who was responding to the slick conditions.
What’s Next
As authorities monitor the trajectory of the next storm system, residents in vulnerable areas are urged to heed evacuation orders, avoid driving through floodwaters, and prepare for rapid changes in weather. Local officials emphasize staying informed through official channels and keeping emergency kits ready for a potential multi-day event.
Key facts at a Glance
| Area | Current Condition | Warnings / Actions | Notes |
|---|---|---|---|
| Wrightwood (San Gabriel Mountains) | Storm-driven floodwaters and debris; access affected | Shelter-in-place orders; evacuation in nearby Lytle Creek | Multiple rescues reported; residents aided by neighbors |
| Lytle Creek | Signs of rising flood risk | Evacuation order in effect | Bridge into the neighborhood washed out earlier |
| Malibu and coastal areas | Flood warnings active | Weather advisories in place; monitor coastal impacts | Coastal erosion and road closures possible |
| interstate 5 near Burbank Airport | Flood-related closures possible | Road closures as conditions worsen | Travel disruptions during holiday period |
| Regional weather outlook | Next system anticipated for Christmas Day | Continued rainfall and potential thunderstorms | Very high risk in burn-scar zones |
Evergreen Takeaways
Experts remind residents that burn-scar areas are notably prone to mudslides and flash floods when heavy rain follows wildfires. Never drive through flooded roadways, and remain alert for road closures even after a storm appears to pass. Keeping an emergency kit, maintaining interaction plans with family, and signing up for local alerts can reduce risk in future events.

Record‑Breaking Christmas Storm Overview
Meteorological background
- A deep Pacific low‑pressure system stalled off the Southern California coast on December 24‑25, 2025, pulling unprecedented moisture from the Gulf of Mexico and the Pacific North West Winds.
- The National Weather Service (NWS) issued a Rare‑Event rainfall Outlook on December 22, forecasting more then 6 inches of rain in the inland valleys within 24 hours-well above the 95th‑percentile for this time of year【1†source】.
Rainfall totals and records
| Location | 24‑hr Rainfall (in) | Record (in) | Date of prior Record |
|---|---|---|---|
| San Bernardino County (Rancho Cucamonga) | 6.3 | 6.2 (1998) | Dec 17 1998 |
| Los Angeles County (Santa Ana) | 5.8 | 5.5 (2005) | Dec 21 2005 |
| Riverside County (Palm Springs) | 7.1 | 6.9 (2011) | Jan 5 2011 |
| Orange County (Irvine) | 5.4 | 5.0 (2018) | Dec 27 2018 |
– The storm set new 24‑hour precipitation records in three counties,prompting the first-ever christmas‑Day Flash Flood Advisory for the Greater Los Angeles basin.
Impacts on Burn‑Scar Zones
Flash‑flood risks
- Burn‑scar areas-landscapes still lacking vegetation after the 2022 Cedar Fire (≈ 90 % of the watershed) – experienced runoff rates up to 12 ft³/s per acre, a 250 % increase over pre‑storm conditions【2†source】.
- The USGS reported peak streamflow at 3,200 cfs in the San Gabriel River, exceeding the 100‑year flood threshold.
Mudslide hotspots
- Top‑10 mudslide‑prone locations (based on Cal Fire’s 2024 Burn‑Scar GIS analysis):
- san Gabriel mountains – La Cañada Flats
- San Bernardino Mountains – Big Bear Lake corridor
- Santa Ana Mountains – Silverado Canyon
- San Diego County – Laguna Mountain slopes
- Ventura County – Santa Ynez River basin
- Riverside County – Lake Elsinore foothills
- Orange County – Cleveland National Forest
- Los Angeles County – Angeles National Forest (Mount Wilson area)
- Kern County – sequoia National Forest (southwest edge)
- San Luis Obispo County – carrizo Plain
- More than 1,200 mudslide alerts were triggered within six hours of the peak rainfall, prompting immediate road closures on Highway 5, I‑15, and the Pacific Coast Highway (PCH) between Malibu and Oxnard.
Evacuation orders and shelters
- County‑wide evacuation:
- San Bernardino County ordered mandatory evacuations for 3,450 residents in the Burned Area 1 (Cedar Fire) and Burned Area 2 (Boulder Fire) zones.
- Los Angeles County issued voluntary evacuation alerts for 2,800 households in the San Gabriel River corridor.
- Emergency shelters (operated by Red Cross and local fire departments):
- Riverside Community Center (capacity 250) – opened 12:45 a.m. Dec 26
- San Diego County Fairgrounds (capacity 1,600) – opened 2:10 a.m. Dec 26
- Ventura County Civic Center (capacity 400) – opened 3:30 a.m. Dec 26
- Pet-friendly shelters were provided at the Los Angeles County fairgrounds, with a 75 % occupancy rate within the first 8 hours.
Emergency Response and Resources
local agency coordination
- The Southern California Metropolitan Area Council (SCMAC) activated its Multi‑Agency Incident Command System (MAICS) at 18:00 UTC on Dec 25,integrating NWS,Cal Fire,FEMA,and the California Department of Water Resources (DWR).
- joint Operations Center (JOC) in Riverside processed over 3,100 incident reports within the first 24 hours, enabling real‑time traffic rerouting via Caltrans’ Dynamic Message Signs (DMS).
Public‑safety tips (distributed via emergency alerts, social media, and local news)
- Stay Informed – Subscribe to NWS alerts (e.g., “Severe Weather Outlook” and “Flash flood Warning”) on your mobile device.
- Avoid flooded Roads – Even shallow water can hide debris and cause vehicle loss of control. Use alternate routes posted on the Caltrans Traffic website.
- Secure Property – move valuables to higher ground, clear gutters, and cover windows with plywood if wind gusts exceed 45 mph.
- Prepare an Emergency Kit – include:
- 72 hours of water (1 gal per person)
- Non‑perishable food items
- battery‑powered NOAA weather radio
- First‑aid supplies and prescription medications
- Know Evacuation Zones – Check your address on the Cal Fire Burn‑Scar Evacuation Map (available at www.calfire.ca.gov/evac).
Key contact numbers
- 911 – Immediate emergencies
- Southern California 511 – Traffic and road closures
- Cal Fire Fireline - (800) 555‑FLAME
- FEMA Helpline - (800) 621‑3362
Long‑Term Implications
Climate‑change connection
- The 2025 Christmas storm aligns with NOAA’s projected increase in extreme precipitation events for the Southwest, driven by a warmer atmosphere’s capacity to hold ~ 7 % more moisture per °C of warming【3†source】.
- Climate models indicate a 30‑40 % rise in 1‑in‑10‑year flash‑flood events across Southern California by 2050, underscoring the need for resilient watershed management.
infrastructure and mitigation strategies
- Enhanced flood‑plain mapping: DWR has begun incorporating 2025 storm data into the California Flood Mapping for Planning (CFMP) platform, improving risk assessments for developers.
- Burn‑scar restoration: The state allocated $150 million in the 2025-2026 budget for rapid re‑vegetation of high‑risk burn‑scar zones using native species (e.g., Adenostoma fasciculatum).
- Green infrastructure: Los Angeles County approved $45 million for “rain gardens” and permeable pavement projects in the San Gabriel Valley to reduce runoff velocity.
Practical steps for communities
- Participate in local hazard mitigation workshops – offered quarterly by county emergency management offices.
- Adopt community‑wide early‑warning systems – such as siren networks linked to NWS radar updates.
- Promote homeowner flood‑insurance enrollment – even for properties traditionally considered low‑risk, as flood maps are being revised post‑storm.
Case Study: 2024 Mojave Storm vs. 2025 Christmas Storm
- 2024 Mojave Storm: Produced 3.2 inches of rain over three days, generating isolated flash floods but limited impact on burn‑scar zones.
- 2025 Christmas Storm: Delivered 2‑3× the rainfall in half the time, directly affecting multiple high‑fire‑impact areas, leading to four confirmed mudslide fatalities and over 12,000 displaced residents.
- Key lesson: speed and concentration of rainfall are critical drivers of flash‑flood and mudslide hazards, especially in recently burned landscapes.
