News Summary
On October 11, 2025, Phoenix, Arizona, set a new daily rainfall record, accumulating 1.01 inches in just four hours, leading to extended flood watches. The National Weather Service warns of potential flash floods and thunderstorms, urging residents to exercise caution due to misleading water depths on roadways.

Phoenix, Arizona experienced a significant weather event on October 11, 2025, breaking its daily rainfall record within just four hours. Rainfall totals reached up to 1.01 inches at Phoenix Sky Harbor International Airport, with various areas accumulating between 0.25 and 1 inch, and some regions receiving even higher amounts.
The National Weather Service had initially set a flood watch that was expected to conclude on Saturday night; however, due to the saturated ground conditions, this alert has now been extended to Sunday evening. Meteorologist Gabriel Lojero has warned that thunderstorm activity is anticipated to pick up again after 7 p.m. Saturday, creating the possibility for intense rainfall throughout the night and into Sunday.
The combination of heavy rainfall occurring within a short timeframe has led to increased flash flood threats in the region. Residents have been advised to exercise caution, particularly regarding water on roadways, where the depth can often be misleading. As much as an additional inch of rain is forecasted for the Valley over the next 24 to 36 hours, prompting concerns for localized flooding.
Conditions are expected to improve later on Sunday into Monday, with only isolated showers predicted thereafter. The ongoing weather pattern is primarily driven by the remnants of Hurricane Priscilla, which continues to funnel moisture into the area throughout the weekend.
Warnings for localized flash flooding and thunderstorms have been issued, particularly impacting south-central Arizona. Thunderstorms may produce brief heavy rains and the potential for hail, with high temperatures expected to hover in the 80s over the weekend. Low temperatures, however, are predicted to drop to the low 60s by the following week.
In particular, parts of the Navajo Nation remain under a flash flood warning until 11:15 p.m. Friday due to previous heavy rainfall, further increasing the region’s vulnerability to flooding-related issues.
Impact of the Weather System
This recent weather system has illustrated the unpredictability of regional weather patterns in Arizona, which can change rapidly. Following a summer that saw unusually dry conditions, this sudden onset of rain can lead to challenges in infrastructure and public safety. As storm response systems gear up for potential flooding, authorities remain vigilant in their monitoring and response efforts.
Preparedness and Safety Measures
Residents are encouraged to remain informed about the latest weather updates and advisories. Safety measures include avoiding flooded roadways and being aware of rapidly changing conditions during thunderstorms, as even minor accumulations can lead to significant issues. Local emergency services are prepared to assist as necessary, ensuring the safety and well-being of the community.
The conditions moving forward will be closely watched, as meteorologists continue to assess the influence of atmospheric patterns stemming from both local weather phenomena and larger systems like hurricanes that impact moisture levels. As the forecast evolves, timely updates will be crucial for public awareness and safety.
