Flash Flood — Sep 28, 2025
A fairly weak cutoff low slowly ejected northward through the area over the course of several days. This feature in combination with sufficient moisture created an environment that supported several days of shower and thunderstorm development. Some of these storms produced locally heavy rainfall and flash flooding, as well as some strong wind gusts.

A weak northern stream shortwave trough moving through the northwest CONUS resulted in the development of high based convection. Some of this convection resulted in strong to severe wind gusts. Additionally, a cutoff low placed off of the southwest CONUS helped advect moisture into southern Utah, leading to convection with periods of sufficiently heavy rain to result in flash flooding over some...
