Potential for Storms and Winds

Isolated showers and weak thunderstorms were possible on March 29 and March 30, particularly south of the Phoenix metro area. Meteorologist Chris Kuhlman noted that most storm activity would likely be isolated and weak.

Gusty winds, with potential gusts of 30 to 40 mph, were expected along the Interstate 8 and Interstate 10 corridors late on March 29, potentially creating areas of blowing dust. There was a 10% to 20% chance of wind gusts exceeding 30 mph in Phoenix itself.
