Weather Forecast for Sunday, Feb. 15

The latest forecast and air quality conditions for the greater Los Angeles area, including beaches, valleys and desert regions.

What they're saying:

The NWS describes the system as "very significant and dangerous," particularly for those near recent burn scars like the Eaton Fire area.

"Striking on a holiday is the only 'good' part of the storm, as there are fewer commuters on the road," officials added.

SUGGESTED: What's open and closed on Presidents Day 2026

What you can do:

• Clear drainage: Ensure gutters and storm drains are clear of debris to prevent localized flooding.
• Monitor burn scars: Residents near recent burn areas should stay alert for weather updates and be prepared to evacuate if debris flow warnings are issued.
• Avoid the surf: Stay away from rock jetties and the water, as large breaking waves and dangerous rip currents are expected.
• Prep for snow: If traveling through mountain passes Tuesday or Wednesday, carry tire chains and an emergency kit.
