Watch vs Warning

Widespread showers and thunderstorms forecast for today/tonight. Persistant showers/thunderstorms will likely lead to flash flooding concerns across northern Arizona. Some storms could be severe in nature and produce gusty/erratic winds, frequent lightning, and hail.

A big increase in moisture is expected starting late tonight through Wednesday night. This is due to a disturbance that will rise up from the Gulf of California this evening. Expect areas of moderate rain and embedded thunderstorms to move south to north during this time frame. Flash Flooding will become a major concern, especially over burn areas, slot canyons and already saturated ground.
