Last Map Update: Tue, Jul 21, 2026 at 6:10:17 pm MDT

Thunderstorms will move northwest at 10 to 15 mph through the evening. A few storms may produce rainfall rates up to 2 inches per hour, which could create localized flash flooding.
Additional slow moving thunderstorms are likely to develop across recent burn scars in the Sacramento Mountains. Efficient rainfall rates up to 1-2" per hour will be capable of producing rapid runoff and flash flooding. Make sure to heed any and all warnings if they are issued!
Daily thunderstorm chances continue throughout the next several days. A slight downtick in storm coverage is likely Thursday, with resurging storms coming this weekend. Most storms will move slowly, so locally heavy rainfall and flash flooding continues to remain a threat, especially for already saturated areas.
An extended period of hot temperatures is going to begin Wednesday, then continue through at least the weekend, with fairly high confidence of this continuing into next week. Moderate to major Heat Risk is likely. Remember to stay hydrated, take breaks if outside, and check on those sensitive to the heat.
