Heavy Rain and Flash Flooding Threat Continues Across the West and Parts of Texas
A widespread threat of heavy rainfall and flash flooding will continue today across much of the western United States and parts of Texas. The greatest concern is across northern Arizona, where repeated thunderstorms could produce several inches of rain, leading to scattered flash flooding, especially in areas with saturated ground. Heavy rain is also possible across portions of New Mexico, where recent wildfire burn scars are especially vulnerable to dangerous runoff and debris flows. Across west and south-central Texas, additional thunderstorms may bring localized flooding, although the heaviest rain is expected to fall west of the areas hardest hit earlier this week. Isolated flooding is also possible along Florida's west coast, the Ohio and Tennessee Valleys, the central Appalachians, and parts of the northern Great Lakes where slow-moving or repeated storms develop.

Warm, Dry, and Breezy Conditions Increase Wildfire Risk in the Northwest
Elevated wildfire danger is expected this afternoon across parts of the Pacific Northwest and the northern Great Basin. A weather system moving along the Pacific Northwest coast, combined with high pressure over the Rockies and Great Basin, will create warm, dry, and breezy conditions that are favorable for rapid fire growth. Areas east of the Cascade Mountains, including the Columbia Basin, will experience the driest conditions, with very low humidity and steady southwest winds. Although winds are not expected to be especially strong, the combination of dry vegetation, low humidity, and persistent breezes will increase the risk that any new fire could spread quickly.
