PHOENIX — Monsoon storms developed along the Mogollon Rim and moved southwest toward the Valley Thursday as of 3 p.m.

Damaging winds, hail, flash flooding and dust are all expected in the Valley Thursday night, according to 12 News Meteorologist Lindsay Riley.

The Phoenix area and locations further west all the way toward Blythe, California, have the best chances for severe storms, according to the National Weather Service.

A blowing dust advisory for southern Maricopa County and western Pinal County is in effect from 3 p.m. to 10 p.m., as the storms and outflows are expected to reduce visibility under one mile and produce 40 mph wind gusts.

Impacted areas in the advisory include south Phoenix, Gilbert, Chandler, Casa Grande and Florence.
