Briefings
From the Forecaster
Friday Flood Watch
Created by the NWS Phoenix WFO
A Flood Watch has been issued for Maricopa County, Northwestern Pinal County, and Southern Gila County on Friday. Showers and thunderstorms will develop across portions of Southern and Central AZ starting early in the morning, with the highest rain rates and best coverage of showers and storms likely during the afternoon into the early evening. Not all areas will see heavy rain, and there remains uncertainty in rainfall totals, but isolated/embedded thunderstorm activity will result in locally heavy rainfall with rates upwards of 1-2" per hour leading to an enhanced potential for flash flooding.
