by Western and Central U.S. — As monsoon season continues, powerful thunderstorms and heavy rainfall are raising concerns for flash flooding and wildfire ignitions across parts of the western and central United States. Meteorologists warn that residents in these regions should remain alert as the severe weather threat persists through the workweek.
Plains Face Increased Flash Flood Threat
The Plains region is experiencing heightened flash flood risks after rounds of heavy rain and thunderstorms on Wednesday. According to FOX Weather, multiple areas are seeing saturated soils and increased runoff, heightening the potential for dangerous flooding.
The National Oceanic and Atmospheric Administration (NOAA) has issued alerts for widespread flash flood threats across portions of Kansas, Missouri, and Oklahoma, designating some areas with a Level 3 out of 4 risk. Meanwhile, parts of the Rockies and Plains are under Level 2 out of 4 flash flood threats, including areas in Idaho.
With rainfall totals already significant this year, additional storms could lead to training thunderstorms—when multiple storm cells pass over the same area—dramatically increasing the risk of flash floods.
Arizona and the Southwest Face Monsoon Fury
Monsoon season remains in full swing across the Southwest. Cities like Phoenix and Tucson, Arizona, have experienced torrential rain, including dramatic haboobs—intense dust storms that briefly plunged parts of Phoenix into darkness.
Despite recent rainfall, Arizona remains in drought conditions. Phoenix recorded its second-wettest day of 2025 on Monday, yet the city still ranks among the 10th-driest starts to any year on record. Tucson is experiencing its third-driest year-to-date, with both cities’ weather records extending back to 1895.
The FOX Forecast Center notes that more than 25 major Southwest cities are among their top-five driest years on record, meaning that while recent rainfall is beneficial, it is not enough to fully alleviate drought stress.
Tropical Storm Juliette Brings Additional Rain
Adding to the monsoon rains, remnants of Tropical Storm Juliette are expected to bring temporary moisture to Southern California and Arizona by Thursday. While not part of the traditional monsoon, these tropical remnants will contribute additional rainfall, providing some relief to parched regions and potentially boosting water reserves.
Central U.S. Rainfall and Flood Risks
Farther east, in the Plains and Rockies, higher rainfall totals are anticipated as storms continue. Widespread 3-5 inches of rainfall are expected, with localized totals potentially exceeding these amounts. The saturated soils in these regions make them particularly vulnerable to flash flooding, prompting officials to warn residents to remain cautious during outdoor activities and when traveling.
Wildfire Concerns Remain
Alongside flooding threats, there is growing concern about wildfire ignitions in areas affected by thunderstorms. The NOAA Storm Prediction Center (SPC) highlights that cloud-to-ground lightning generated by these storms could ignite wildfires, particularly in dry regions that remain parched despite recent rainfall.
Officials urge residents to monitor local advisories, avoid outdoor fires, and exercise caution with electrical equipment and activities that could spark a fire. With drought conditions lingering in much of the West, even brief dry periods between storms can create highly flammable conditions.
Precautionary Measures for Residents
Experts recommend several precautionary measures as severe weather continues:
- Stay informed: Monitor weather alerts and warnings from NOAA, local authorities, and trusted news outlets.
- Prepare emergency kits: Include essentials like water, flashlights, batteries, and first-aid supplies.
- Avoid flooded areas: Do not attempt to drive or walk through floodwaters. Even shallow water can be dangerous.
- Exercise wildfire safety: Avoid outdoor burning, and ensure smoke detectors are functional at home.
With monsoon season in full effect, officials emphasize that communities must remain vigilant. These combined threats of flash flooding and potential wildfire ignitions underscore the need for preparedness and caution throughout the West and central U.S.
