Hot temperatures climbing into the 100s, with gusty winds and blowing dust are in store today for the Las Vegas Valley, according to the National Weather Service.
The weather service has issued a Wind Advisory for the valley from 2 p.m. through 11 p.m. today.
Winds will be from the southwest between 20 and 30 mph, with gusts to between 40 and 50 mph, forecasters said.
The strong crosswinds may make driving difficult at times, while blowing sand and dust might rapidly lower visibilities to less than a mile, they said.
The weather service has also issued a Red Flag Warning that strong winds and dry conditions could spread outdoor fires quickly through the region.
The wildfire warning is in effect from 1 p.m. to 9 p.m. today in southern Nevada and northwest Arizona.
The gusty winds below the canyons and along the lower slopes of the mountains could reach 70 mph at times, they said.
