Atmospheric River Brings Christmas Showers to Arizona, With Flood Watch in Mohave County

Air-quality regulators posted a High Pollution Watch for Thursday due to increased holiday burning.

Overview

  • Scattered to widespread showers are expected through Christmas, with Phoenix neighborhoods forecast to receive roughly 0.25 to 0.5 inch of rain and higher totals possible in northwestern Arizona.
  • A Flood Watch remains in effect for Mohave County through Thursday morning because of potential excessive runoff in low-lying and flood-prone areas.
  • Wind Advisories cover parts of northwestern Arizona for Christmas Eve and Christmas Day, with gusts in Mohave County potentially reaching about 50 mph.
  • Snow levels remain elevated near 9,000 to 10,000 feet, keeping Flagstaff largely rainy for now, with cooler air and additional shower chances possible this weekend.
  • Local stations declared Weather Action Days for Wednesday and Thursday, and ADOT urged drivers heading north to prepare for wintry conditions and avoid stopping on highway shoulders.
