Heavy Rain May Trigger Localized Flash Flooding Across the Southwest, Southeast, and Midwest
Heavy rain and thunderstorms are expected to affect parts of the Southwest, Southeast, Appalachians, Mid-Atlantic, and portions of the Plains and Upper Midwest through Tuesday and Tuesday night. Southern Arizona faces the greatest concern, where slow-moving storms could produce intense rainfall capable of causing flash flooding, especially in mountain areas, burn scars, washes, and low-lying locations. Elsewhere, scattered thunderstorms from the Southeast into the Mid-Atlantic may bring brief downpours, with localized flooding possible in areas that have already received heavy rain, as well as in cities and rugged terrain. Across the Central Plains and Upper Midwest, thunderstorms developing along a slow-moving cold front could bring several inches of rain, leading to isolated flooding where storms repeatedly track over the same locations.

Dry, Gusty Weather Raises Wildfire Risk Across the West as Storms Continue in the Southeast
Warm, dry, and breezy weather will increase the risk of wildfire spread across parts of the Great Basin and Colorado Plateau today. Gusty west winds, very low humidity, and dry vegetation will create conditions that allow fires to start and spread more easily. Similar hot and dry weather is expected in parts of northern California, Oregon, and Washington, where locally gusty winds could briefly increase fire danger despite generally lighter winds. Meanwhile, thunderstorms are expected to develop across portions of the Southeast during the afternoon and evening, bringing locally heavy rain, lightning, and gusty winds to some areas. Residents in fire-prone regions should avoid activities that could spark fires and stay alert for changing weather conditions.
