The National Weather Service in Phoenix has issued a Severe Thunderstorm Warning for Maricopa County, located in south central Arizona, effective immediately and lasting until 9 p.m. MST. The warning comes as a severe thunderstorm, which was initially detected over Painted Rock Dam, 18 miles north of Gila Bend, has been moving northeast at a speed of 10 mph.
Adding to the concern, the National Weather Service has also issued a Flash Flood Warning for Pinal County in southeastern Arizona, set to remain in effect until 12:45 a.m. MST. Doppler radar has indicated that thunderstorms in the warned area are producing heavy rain, with between 1 and 1.5 inches of rainfall already recorded. There is a possibility of an additional inch of rain, which could lead to flash flooding.
Meteorologists from the National Weather Service reported that as of 8:28 p.m. MST, a severe thunderstorm was located near Wenden, 29 miles south of Alamo Lake, and was moving northeast at a speed of 15 mph. The intense weather conditions are a result of the state's monsoon season, which typically spans from June 15 to Sept. 30.
During the monsoon season, Arizona experiences intense heat, moisture surges, and atmospheric instability, leading to the formation of clouds and an increased likelihood of storms, particularly in the afternoon. While storms are most frequent during the monsoon, they can occur year-round, ranging from short-lived and spotty to those that unleash strong winds, lightning, and heavy rainfall.
A severe thunderstorm warning is issued when an area is experiencing or is about to experience a storm with winds of 58 mph or higher and/or hail an inch in diameter or larger. It is crucial for residents and visitors in the affected areas to take immediate precautions to ensure their safety.
For those in the warning area, the following tips are recommended:
- Seek indoor shelter at the first sound of thunder, as lightning strikes can occur miles away from the storm. - Resume outdoor activities only 30 minutes after the storm has passed. - Avoid using electronics, plumbing, and windows during the storm. - Remember to bring pets inside. - If there is time, secure loose objects outside to prevent them from becoming dangerous flying debris in high winds.
The warning comes as the 2026 monsoon season continues to bring unpredictable weather to the region. While the season has been marked by periods of intense heat and occasional dust storms, the recent severe thunderstorm warning serves as a stark reminder of the potential dangers that the monsoon can bring.
Meteorologists are closely monitoring the situation and are advising residents to stay updated with the latest weather forecasts and warnings. The National Weather Service will continue to provide updates and advisories as needed to ensure the safety of the community.
