Flood Watch

The ongoing threat of excessive rainfall and flash flooding through Sunday evening will increase during the day Monday. On Monday, there is a Moderate Risk (categorical 3/4) of Excessive Rainfall for portions of southern to central Utah. The highest threat area will be rain sensitive basins such as recent burn scars, slot canyons, typically dry washes, and slickrock areas.

Multiple rounds of showers and thunderstorms from this afternoon through Monday evening will be capable of producing heavy rainfall that could lead to flash flooding. Those with outdoor plans in flood prone areas such as slot canyons, slickrock areas, recent burn scars and normally dry washes of southern Utah should consider alternate plans and have multiple ways to receive weather warnings!
