Moisture associated with the remnants of Tropical Storm Rachel will impact Utah this weekend bringing widespread rainfall totals ranging from 2-4". Some highly localized amounts to 6-8" are also possible, particularly across terrain-favored locations in southwestern Utah, the Book Cliffs, and Bear River Range. * WHAT...Flooding caused by excessive rainfall is possible. * WHERE...A portion of Utah, including the following areas, Western Millard and Juab Counties, Bear Lake and Bear River Valley, Cache Valley/Utah Portion, Eastern Box Elder County, Great Salt Lake Desert and Mountains, Northern Wasatch Front, Salt Lake Valley, Tooele and Rush Valleys, Utah Valley, Wasatch Back, Wasatch Mountains I-80 North, Wasatch Mountains South of I-80, Western Uinta Basin and Western Uinta Mountains. This includes recent burn scars such as Rocky Canyon. * WHEN...From late Saturday night through Monday afternoon. * IMPACTS...Excessive runoff may result in flooding of rivers, creeks, streams, and recent burn scars. Flooding may occur in poor drainage and urban areas. Extensive street flooding and flooding of creeks and rivers are possible. * ADDITIONAL DETAILS... - Moisture associated with the remnants of Tropical Storm Rachel will move into northern Utah this weekend producing a prolonged rainfall event. In particular, moisture interacting with a frontal boundary across far northern Utah may yield locally heavier rainfall totals compared to other locations. As a result, areal flooding is expected across northern Utah this weekend. - http://www.weather.gov/safety/flood
