Phoenix, Ariz. – Arizona drivers face a double threat Thursday as heavy rain combines with poor air quality across the Valley. Flood warnings remain in effect, and standing water may close roads before the Friday morning commute.
According to the National Weather Service in Phoenix, excessive rainfall triggered multiple flood advisories in Maricopa County. Low-lying areas, including stretches of Interstate 10 and neighborhood washes, could quickly become impassable. Officials urge drivers to avoid flooded streets and never attempt to cross barricades.
Flood risks are expected to linger through late Thursday, especially in South-Central Arizona. Doppler radar showed widespread rainfall totals exceeding an inch, with isolated areas receiving more. Emergency crews remain on alert for swift water rescues.
Adding to the hazard, the Arizona Department of Environmental Quality extended an ozone pollution advisory through Thursday. Sensitive groups, including children, seniors, and people with asthma, should limit outdoor activity. The mix of stagnant air and storm activity is expected to worsen breathing conditions.
Residents should prepare for continued travel delays and possible school or business impacts. Charge devices, avoid unnecessary trips, and monitor updates from the National Weather Service.
