ESFSLC The remnants of Tropical Storm Rachel will merge with a fall-like storm system over the western United States, bringing moderate to heavy rainfall and a resulting threat of flooding. Widespread rainfall of 1 to 3 inches is expected, locally in excess of 3 inches, particularly across south aspects of southern Utah mountains, between late Saturday and Monday morning. Expect many area waterways including streams, rivers, normally dry washes, creeks, and slot canyons to have rising, fast flows by Sunday evening. Current forecasts do not bring any rivers to flood stage, but this will be monitored as the fine details of heavy rain bands become more confident. Those with activities near rivers, streams, creeks and recent burn scars should closely monitor the forecast over the next several days. Those with outdoor plans Sunday onward that include any travel near waterways across Utah should consider alternate plans. Scattered showers and thunderstorms will remain possible through at least Wednesday. While the rainfall rates with these additional rounds of precipitation will generally be lower, areas that receive significant precipitation during the weekend will be extra sensitive to any additional rainfall.
