Statewide Warnings & Alerts

March 30 2025

Residents in Arizona, particularly in the Black Mesa, Chuska Mountains, Defiance Plateau, Little Colorado River Valley, Mogollon Rim, Painted Desert, Kaibab Plateau, Grand Canyon Country, and Coconino Plateau, are advised to brace for strong winds. The National Weather Service has issued a Wind Advisory effective until early morning April 1, warning of southwest winds reaching 20 to 30 mph with gusts up to 50 mph. Gusty winds are likely to disrupt unsecured objects, cause tree limbs to snap, potentially leading to power outages, and create difficult driving conditions, especially for high profile vehicles. Extra caution is advised for those in the affected areas.

Arizona Flow History


Arizona is a state with arid to semi-arid climate conditions. Major surface flows include the Colorado and Gila Rivers, with the former having significant impacts on water supply and hydroelectricity generation. Reservoirs and dams, such as Lake Powell and Hoover Dam, play critical roles in water storage and management. The state's hydrology is primarily influenced by snowmelt from the Rocky Mountains and the monsoon season, which brings heavy rainfall to the region during the summer months. Watershed data indicates that the Salt and Verde Rivers are the primary sources of water for the Phoenix metropolitan area. Climate change is expected to exacerbate water scarcity issues in the region, with reduced snowpack and increased temperatures leading to higher evaporation rates and reduced water availability.
