Much needed Southwest rainfall leads to flooding in Arizona

Phoenix had its wettest day of 2022 on Saturday with .76 inches of rain. The same storm system bringing rain and snow to California will keep scattered chances for rain and possibly flooding in the forecast for the Southwest through Tuesday.

PHOENIX – Several inches of rain forecast across parts of the Southwest through Monday will benefit parched areas of the desert. Still, while helpful to drought-stricken areas, the heavy rainfall is also causing some localized flooding in Arizona.

On Saturday, Phoenix Sky-Harbor International Airport recorded .76 inches of rain, making it the wettest day of 2022 for the city. 

FOX Forecast Center meteorologists say this rainfall is notable because it comes after the typical monsoon season when the average amount of rain for the entire month of December is .74 inches.
