A strong dust and rainstorm swept into the Phoenix area Saturday night, followed by thunderstorms that brought heavy rain.

The National Weather Service issued a dust storm warning and said that blowing wind would hamper visibility for drivers. A flash-flood warning was issued for central Maricopa and west-central Pinal counties.

About 1,200 Salt River Project customers in the San Tan Valley area lost power as a result of the storms.

On Sunday, a strong wave of moisture from Hurricane Norbert is expected to push its way into Arizona and the Valley, bringing chances of rain through Tuesday.

Some of the storms could be severe Sunday and Monday with localized flooding and strong winds, 12 News meteorologist Matt Pace said.
