California — Dawn breaks through a thick wall of cloud over Los Angeles, casting a dim, muted glow across rain-soaked streets. Water pools along curbs, steam rises faintly from warm pavement, and the sound of steady rainfall mixes with an unusual early-morning hush. Residents waking up can sense the urgency before even checking the radar.

A potent Pacific storm continues to send wave after wave of heavy rain across the Los Angeles Basin, and multiple Flood Watches and Flood Advisories remain in effect. This system arrives at a critical moment, with early Thanksgiving travel already increasing and storm drains struggling to keep pace. Drivers should avoid canyon routes, low-lying intersections, and freeway underpasses where water rises fastest. Travel times along I-5, I-10, and the 101 may double during peak rainfall.

To be fair, the region is no stranger to November storms—yet this one carries extra risks. Models show intense pockets of rain capable of producing rapid runoff, especially near recent burn scars. Officials warn that debris flows could develop quickly, even without a full thunderstorm. Anyone living near slopes should keep alert for sudden changes in water flow or shifting soil.

Rain stays widespread through today, with some storms producing brief bursts of extremely heavy rainfall. New rainfall of 1 to 2 inches is possible in many urban zones. By tonight, showers continue but gradually lose intensity.

Sunday brings slower, lighter activity, though afternoon showers may still impact outdoor plans. Monday keeps clouds and scattered showers over the region, which could again affect early travel for commuters and flyers navigating LAX.

After all, this is the type of early-season pattern that can shape the run-up to Thanksgiving—wet, unpredictable, and highly impactful.
