Las Vegas is soaking up clear skies and warm air this Wednesday, March 4, 2026, with neighborhoods cruising into the mid-70s and an official high near 77°F on tap for the valley. It feels calm and mellow now, but that is about to change: forecasters say winds will crank up on Thursday, and a Wind Advisory is already up for much of the region.
Wind Advisory for Thursday, March 5
The National Weather Service in Las Vegas issued a Wind Advisory on Wednesday for Thursday, March 5, 2026, calling for northwest winds of 20 to 30 mph with gusts up to 45 mph from 8 AM to 10 PM PST. The advisory flags dangerous crosswinds on Interstate 15 and Interstate 40 and warns that blowing dust near dry lakebeds could cut visibility in a hurry. "Winds this strong can make driving difficult, especially for high-profile vehicles. Use extra caution," according to NWS Las Vegas.
Travel and Boating Impacts
Drivers of trucks, RVs and vehicles towing trailers should brace for tough stretches on exposed roadways and plan on extra time to deal with crosswinds and sudden gusts. Out on the water, small boats and personal watercraft are urged to steer clear of Lake Mead, Lake Mohave and other reservoirs while waves build and conditions turn choppy, as a March 3 report noted that marinas were already advising caution. At home, now is the moment to lock down patio furniture, tarps and light yard items so they do not end up scattered across the neighborhood once the advisory kicks in.
Looking Ahead
Forecast discussions indicate gusty winds will hang around through Saturday, with a relative lull on Friday, although the strongest post-frontal northwesterly gusts are still expected from Thursday into Friday night. Temperatures slip into the upper 60s on Thursday, then rebound into the upper 70s by Sunday, so planning outdoor events for the calmer morning hours could pay off.
