Downtown Los Angeles woke up Tuesday, February 17, 2026, to a cool, damp start in the mid 40s as a strong Pacific storm moved into Southern California. Light showers are expected to fill in through the afternoon, turning into steadier rain by evening with a few thunderstorms in the mix and strengthening south to southwest winds overnight. Drivers and pedestrians alike should plan for slick roads and pockets of standing water in low-lying spots around downtown and nearby neighborhoods.
Evening Into Early Wednesday: Flood Watch and Strong Winds
A Flood Watch is in effect from Tuesday evening through the early hours of Wednesday, February 18, with the National Weather Service warning of multiple rounds of rain that could lead to rapid runoff and flash flooding, especially near recent burn scars. A Wind Advisory covers coastal and valley areas from about 5 p.m. Tuesday through 6 a.m. Wednesday, calling for southwest gusts generally in the 20 to 30 mph range, with peak gusts up to 45 mph along the coast and in many valley locations. Foothills and mountain areas could see even stronger gusts. According to NWS Los Angeles/Oxnard, combined rainfall totals could approach an inch across coastal and valley zones, with higher amounts expected in the mountains.
City Prep and Commute Advice
Mayor Karen Bass has ordered city crews to pre-position storm response teams and urged Angelenos to sign up for emergency alerts and steer clear of low-water crossings, according to the Mayor's Office. Evening surface streets are likely to run slower than usual, with possible lane closures where water collects. If you can postpone nonessential trips during the evening rush, it might save you some headaches. Check NotifyLA and local transit sites for any service changes, and build in extra time if you are taking buses or trains.
Mountain Passes and the Grapevine
Snow levels are forecast to drop to around 3,000 feet by Wednesday morning, prompting Winter Storm Warnings for the mountains and raising the odds of snow on I-5 over the Grapevine. That combination could bring travel delays and brief closures. Anyone headed over the passes should be ready for chain controls, icy ramps, and reduced visibility during the overnight and early-morning hours and should carry tire chains or have an alternate route in mind.

Coastal Hazards
Along the beaches, large surf and elevated high tides are expected through Friday, increasing the risk of minor coastal flooding and dangerous rip currents at west-facing shores. Locals are urged to stay off exposed jetties and seawalls during high surf periods and to expect possible lifeguard closures or beach advisories during peak tides and swell events. If you live close to the water, move vehicles and valuables to higher ground ahead of high-tide cycles.
Quick Safety Tips
Secure loose patio furniture and trash cans before the strongest winds arrive, never drive through flooded intersections, and slow down on wet roads to avoid hydroplaning. If you live below a burn scar, review your evacuation route and keep an emergency bag packed and accessible.
