The National Weather Service (NWS) has issued a Flood Watch, Tornado Warning, and Severe Thunderstorm Warning for the Los Angeles area, alerting residents to significant weather hazards over the next several days.
By News Desk
The warnings are due to an ongoing atmospheric river system expected to bring prolonged heavy rain, strong winds, and an increased risk of flooding across the region.
Flood Watch: Significant Flooding and Debris Flow Risks
A Flood Watch remains in effect through Friday, December 26, at 4:00 pm, as heavy rainfall is expected to cause widespread flooding. According to the NWS, rain lasting through Thursday evening could exceed one inch per hour at peak intensity. Affected areas include the Greater Pasadena area, the San Gabriel Valley, and locations with recent burn scars, where the risk of debris flows is especially high.
Residents in flood-prone areas are advised to prepare for possible evacuations and closely monitor weather updates.
Wind Advisory: Gusty Winds in Los Angeles and Ventura Counties
A Wind Advisory is also in effect through Thursday, December 25, at 3:00 pm for Los Angeles and Ventura counties. South to southeast winds of 20 to 35 mph are expected, with gusts reaching up to 55 mph. Strong winds may blow around unsecured objects, creating hazards for travel and increasing the potential for property damage.
Saturated soils from the storm may raise the risk of downed trees, particularly in areas impacted by previous rainfall. Drivers, especially those operating high-profile vehicles—are urged to exercise caution, as gusty conditions may make travel difficult.
Sierra Madre
Athens Services announced that trash and recycling collection will be suspended on Wednesday, December 24, for Sierra Madre residents in the Woodland Drive and canyon areas. Residents are asked not to place bins on the street, as they could block emergency access and pose hazards during flooding or debris flow events. Regular service will resume on Wednesday, December 31.
Pasadena
The City of Pasadena announced that due to the significant storm, all Arroyo Seco trails and surrounding areas will be closed beginning Wednesday, December 24, and will remain closed until further notice. Residents are urged to avoid the area and follow all posted safety advisories.
The Pasadena Bad Weather Shelter is open through December 27. Housing and Fire Department staff have confirmed that weather activation criteria have been met based on the current National Weather Service forecast. While capacity and services will be limited during this opening week, full operations will resume in January; even with scaled-back services, the shelter provides critical support during urgent weather conditions. The shelter activates on nights when the forecast predicts temperatures of 40°F or below, a 40% or greater chance of rain, or high winds of 40 mph or more. Line-up begins at 6:30 pm, with doors opening at 7:30 pm, at Trinity Lutheran Church, 997 E. Walnut Street, Pasadena, CA 91106 (entrance at the back of the church on Locust Street). Community members can check nightly activation status by calling (888) 915-8111.
Wrightwood area
San Bernardino County is experiencing heavy debris flow and flooding in the Wrightwood area. State Route 2 into Wrightwood is closed from State Route 138 due to flooding and debris flows in nearby burn areas. Residents/drivers are asked to avoid the area for safety.
Safety tips
Be extra cautious at night when visibility is limited, as flooding hazards can be harder to see. Even just six inches of water can cause a vehicle to lose control or stall, and floodwater may hide dips or damaged or washed-out roadways beneath the surface. Stay alert for debris, downed power lines, or stalled vehicles near flooded areas.
Thunderstorms and Travel Disruptions Expected
Thunderstorms could further complicate conditions, with the NWS forecasting additional rainfall and possible thunderstorms on Thursday. Travelers during the busy holiday period are advised to stay informed, as the combination of heavy rain, strong winds, and flooding could result in road closures and significant delays.
Residents are encouraged to prepare emergency kits, remain alert through local news and weather alerts, and take necessary precautions when traveling in affected areas.
Stay safe and remain prepared as this powerful storm system continues to impact Southern California through the holiday weekend.
