Heavy rain is expected this weekend as tropical moisture combines with an incoming cold front, according to an October 8 report from NWS Salt Lake City. The weather system is forecast to begin on Saturday, with particularly heavy rain expected on Sunday.
Widespread rainfall amounts of 1 to 2 inches are forecast, though local amounts could reach up to 3 inches. NWS Salt Lake City stated that those planning outdoor activities should strongly consider alternatives due to the forecast.
The wide range in rainfall forecasts is attributed to uncertainty regarding the track of Rachel and how it will interact with the cold front. Forecasts through Monday morning show a reasonable range for both low-end and high-end rainfall totals.
