A wall of dust approaches a Maricopa neighborhood.

The Maricopa area is under another dust storm warning until 7 p.m. tonight and an excessive heat watch from late Thursday through Saturday evening.

According to the National Weather Service, north central and northwest Pinal County can expect wind gusts up to 40 mph and visibility less than a quarter of a mile.

Be ready for a sudden drop in visibility to near zero. If you encounter blowing dust or blowing sand on the roadway or see it approaching, pull off the road as far as possible and put your vehicle in park. Turn the lights all the way off and keep your foot off the brake pedal.

The excessive heat warning is triggered by temperatures of 112-116.
