TUCSON, Ariz. – After a soggy holiday weekend, Southeast Arizona remains under a Flood Watch through Monday afternoon as rounds of moderate to heavy rain continue to drench the region. Drivers along I-10, I-19, and rural routes across Pima and Cochise counties should expect ponding on roads and reduced visibility this Columbus Day.
According to the National Weather Service in Tucson, rainfall totals from this three-day system could reach up to 3 inches in some mountain areas, with isolated heavier pockets possible in the Santa Cruz River Valley, Catalina Mountains, and near Sierra Vista. Streams and low-lying desert washes may quickly flood, creating dangerous conditions for travelers and residents alike.
By Tuesday morning, high pressure builds in, bringing dry, sunny skies and a noticeable warm-up. Cleanup from localized flooding could continue into early Tuesday, especially across rural washes and trail areas. Those returning to work and school should allow extra time for any lingering detours or debris-covered roads.
The midweek stretch turns seasonably pleasant, marking a welcome shift for fall outdoor plans — from pumpkin patches to evening hikes — as daytime highs climb back into the low to mid-80s. No additional rainfall is expected through late week, and clear skies will dominate heading toward next weekend.
Residents are urged to stay alert for any lingering Flood Warnings through Monday and to avoid crossing flooded roads. Always remember: Turn around, don’t drown.
