The Tucson metro area didn't see much measurable rain in the last 24 hours, but a storm rolling in from the south promises most of the city will see some moisture this afternoon. 

Scattered showers are predicted throughout the city with some already developing in areas surrounding Tucson including the Tucson Mountains, Vail, Corona de Tucson and Saguaro National Park East, according to the National Weather Service.

Areas west of Interstate 10 are most at risk for flash floods. 

Wind gusts could reach up to 50 mph.
