Monsoon Storms Sweep into the Valley: Join 12News for Live Coverage!

Severe storms have begun moving into the Phoenix Valley from northern Arizona, prompting the National Weather Service (NWS) to alert boaters at Bartlett Lake and Lake Pleasant to seek safety immediately.

At approximately 4:22 PM on Saturday, the NWS posted a warning on X, formerly Twitter, emphasizing the necessity for boaters to vacate the water swiftly as strong winds approached the lakes. The post highlighted the rapid onset of hazardous conditions at Horseshoe Lake and nearby areas.

Adding to the urgency, this weather event followed a record-setting morning low temperature of 91 degrees at Phoenix Sky Harbor International Airport, breaking the previous record of 90 degrees, set in 2019. The current weather could signify the last day of temperatures exceeding 90 degrees this year.

Phoenix has also recorded its 58th day of temperatures hitting 110 degrees in 2024, just shy of the record for the date. Rainfall, with amounts varying from 0.01 inches to 1.53 inches, was reported between Wickenburg and Prescott on Friday night.

Flash flood warnings are now active in various regions. Gila County near Horton Creek Trail remains under alert until 5:45 PM, with a second warning covering areas including Strawberry and Pine until 6 PM. Additionally, Yavapai County faces flash flood warnings until 7 PM, affecting Pine Mountain, Sycamore Creek, and Yellowjacket Creek.

A broader flood advisory is in place until 6:15 PM for Prescott and its surrounding areas, reinforcing the need for caution.

Reports indicate storms in the northwest parts of Maricopa County and La Paz County are expected to diminish after sunset. Residents should remain vigilant as winds carry dust across northern Valley highways, especially on Loop 303, reducing visibility near open fields and construction sites.

The Arizona Fire & Medical Authority has urged residents to safeguard themselves from potential hazards associated with flooding. Essential precautions include turning off electrical mains if safely accessible, avoiding contact with water and powered appliances, and ensuring combustible liquids are stored securely away from any heat sources.

This weather situation serves as a reminder of Arizona’s volatility in terms of climate, emphasizing the importance of preparedness and response during severe weather events.
