More Rain To Come In Valley; Snow Expected In Northern Arizona

Published: Friday, December 23, 2016 - 2:04pm

The weather system that has dropped heavy rain on parts of the Valley has left behind wet streets and swelling desert washes, and there’s more to come.

Some parts of the metro area received more than 1 inch of rain in a 24-year hour period.

A stretch of the North Valley Parkway in north Phoenix was closed Wednesday because of flooding, and photos posted on social media showed cars stranded and washes flooded out.

Pumps were activated along I-17, and crews had to clean up water on Interstate 10 in west Phoenix.

More rain is expected tomorrow, and ADOT spokesman Doug Nintzel says the incessant showers could make holiday travel conditions treacherous this weekend, especially in more rural parts of the state.

“When this type of storm happens, the heavy rain at times, we certainly need to caution drivers to watch for any falling rocks that could be loosened by runoff,” Nintzel said.

That will be especially true tomorrow when there’s a 90 percent chance of precipitation, with as much as a half-inch of rain or more possible around the Valley. If you’re headed to northern Arizona for the holiday weekend, snow accumulations of 6 to 10 inches are expected tomorrow in the high country.
