Las Vegas is starting today under clear skies and mild temperatures, but the calm is on borrowed time. Gusty southwest winds are set to ramp up this afternoon, followed by a second weather system that brings rain late tonight into Wednesday. Daytime highs should still reach near 62°F before winds ease a bit overnight, so outdoor plans look fine early on, though the evening and late-night commute could be a very different story.
Afternoon Winds Pick Up
According to the National Weather Service Las Vegas, a Wind Advisory is in effect through 7:00 a.m. PST Wednesday, 2026. South-southwest winds are expected to run generally 12 to 26 mph, with local gusts that could reach up to 50 mph. Forecasters warn those stronger bursts can make driving tough for high-profile vehicles and may send unsecured objects flying, with the potential for some tree damage and brief power outages.
Before the afternoon peak, residents are urged to tie down or bring in patio furniture and lighter yard items, so they do not end up visiting the neighbors. Drivers should also plan a little extra time for commutes along exposed stretches, especially on corridors like parts of I-15.
Rain And Mountain Snow Tonight
After midnight, rain showers are likely, with about a 70% chance of precipitation and a low near 45°F, and temperatures may tick up slightly overnight. Snow levels are expected to drop to around 4,000 to 4,500 feet, which could create slick travel over Mountain Springs, Mountain Pass and I-40 near Fort Rock by Wednesday morning.
Higher neighborhoods near Red Rock Canyon could pick up flurries or a light dusting, although significant accumulations on the valley floor are not expected. Anyone heading over mountain passes should check on road conditions before hitting the highway.
Airport, Lake And Commute Impacts
Harry Reid International Airport may see gusty crosswinds this afternoon and evening, with speeds roughly 35 to 45 mph at times, which could mean delays along with bumpy approaches and gusty conditions on taxiways.
Out on the water, small craft on Lake Mead and Lake Mohave will be dealing with hazardous waves, and boaters are urged to stay off the lakes until winds calm down. The strongest gusts are expected from mid-afternoon through early evening, so drivers of high-profile vehicles or those towing trailers should try to avoid exposed roadways or delay trips if possible.

What To Do
Residents are advised to secure loose outdoor items, slow down on bridges and overpasses, and build in extra travel time during the peak gusts. If you have late-night or early Wednesday plans, expect a wet commute after midnight and check updated forecasts before heading for higher routes. If you are bound for the mountains, pack chains just in case.
Spotters and residents are encouraged to report hazardous conditions to local authorities so agencies can respond quickly where problems develop.
