Widespread heavy rainfall is expected to occur across the entirety
of the forecast area starting Saturday afternoon/evening as Tropical
Storm Rachel transitions to an extratropical system to our southwest
and interacts with a strong midlevel trough. Widespread rainfall
amounts from 1-2" are expected across much of the forecast area,
with localized amounts potentially reaching 3+" across locations
such as higher terrain locations across southwest Utah, the Book
Cliffs, and locations within and adjacent to the Bear River Range.
