Live Status
As of the Monday morning desk, October 12, 2026, the national picture is Quiet Pulse. SPC Day 1 lists no severe thunderstorm probability areas and no watches. Organized severe from Isaias remnants closed overnight and stayed closed. Isolated thunderstorms possible near a cold front across the Great Lakes or in the Intermountain West under southwest flow, but no severe threat forecast. Zero local storm reports.
WPC Day 1 ERO holds the Slight Risk over the Great Basin and Southwest (western/central Mogollon Rim into northwest Arizona, Wasatch and canyon areas of Utah). Residual moisture from Tropical Storm Rachel supports isolated to scattered thunderstorms with locally heavy rain possible through the day into evening. Antecedent wet ground, burn scars, and slot canyons keep flash-flood potential elevated even after warnings expired. Pattern expected to shift east after Monday night.
No named tropical cyclone threatens or has just hit U.S. land. Isaias is fully dissipated. Residual Rachel moisture is the sole residual tropical influence, tracked by WPC. Residual minor river flooding persists in the Carolinas and other basins from prior rains; non-severe. High wind products in the Intermountain West are non-severe.
