Flood Watch Sunday

Mountain Snowfall Sun-Mon AM

Happy Halloween! 🎃 With scattered showers and thunderstorms spreading northward through the day, chances for soggy trick-or-treating conditions will be hit-or-miss through the evening. Precipitation becomes more widespread through the remainder of the night, with rain likely for many after midnight.

A Winter Weather Advisory is in effect starting tonight through Monday morning, as a cold front brings decreasing snow levels resulting in accumulating mountain snow, mainly above 8000 feet. Travel could be difficult at times over mountain routes, specifically Sunday evening into Monday morning.

⚠️🌧️A Flood Watch has been issued for Sunday across much of southern Utah, with widespread precipitation expected to develop late Saturday night ahead of a cold front. Heavy rainfall may result in flash flooding in normally dry washes and slickrock areas.

A cold upper-level system interacts with deep moisture associated with an atmospheric river Sunday through Monday morning, allowing for substantial snowfall accumulations especially above 8000 feet. Use caution if traveling over mountain routes as even light snowfall accumulations can result in difficult travel.
