Northwest winds in the central valley could gust to 35 mph with velocities in the desert and mountain areas up to 60 mph. The high should be near 66.

A wind advisory runs from 6 a.m. to 10 p.m. Sunday.

The weather service reported a massive dust plume near Jean around noon Sunday. Nipton and Primm were under dust storm warnings until 3 p.m. Sunday afternoon.

All southbound lanes on Interstate 15 were closed around noon near the California-Nevada border, according to to the Nevada Department of Transportation. Lanes reopened about 20 minutes later.

A traffic advisory was still in effect at the border Sunday afternoon due to dust. NDOT said travelers could experience intermittent closures due to low visibility on the California side of the interstate, and should expect delays.

Serious blowing dust persists along I-15 between Nipton Road and Primm.

The interstate remains closed and the Dust Storm Warning has been extended until 3PM. Avoid travel in this area! #nvwx #cawx https://t.co/YxDB3mm5ap
