The Phoenix metro area is under a significant-weather advisory, as a band of thunderstorms was moving into the region from the northeast, bringing high winds, blowing dust and the threat of rain and lightning across a wide area.
A dust advisory was issued just before 8 p.m. for all of Maricopa County and was expected to expire at 8:30 p.m.
Earlier, a severe-thunderstorm warning was issued for Fountain Hills and other areas of the far northeast Valley just after 7:15 p.m. Tuesday, as another round of monsoon activity moved in. The advisory was issued later to expand across most of the metro Phoenix area.
A dust storm was starting to hit the Valley along the northwest portions of Loop 101 and Loop 202 by 7:30 p.m., the Arizona Department of Transportation said.
Rain fell in some areas of the northeast Valley as the storm passed, with nearly 0.7 inches falling in the Fort McDowell area by 8 p.m.
Fountain Hills was hit with 0.16 inches of rain while the areas around Carefree and Cave Creek saw between 0.04 and 0.08 inches.

The National Weather Service said the storm was generally along and north of the Salt River as of 7:15 p.m., moving southwest.
The Weather Service said the storms were nearing the northeast Valley by about 6:45 p.m. and threatened to bring 40 mph winds, lightning and brief periods of heavy rain to the area.
The storm was expected to move across the central and northern parts of the Phoenix metro area as the evening went on, the Weather Service said.
The Weather Service predicted that the monsoon would primarily affect drivers along Interstate 17 and State Route 51 in northern parts of the Phoenix area.
