Lift associated with the deep upper-low and lingering moisture
will continue to lead to thunderstorms with locally heavy rainfall
across portions of the Great Basin today, though with the
upper-low now mainly providing the impetus for storms rather than
an association with the remnants of Rachel. There is a Slight Risk
Excessive Rainfall Outlook in effect Monday for the risk of
scattered flash flooding, primarily for terrain sensitive areas
such as burn scars and within slot canyons. Storms will start
taper off Tuesday as the upper-energy begins to shift eastward and
conditions begin to dry out, though a lingering isolated flash
flood threat will remain for portions of western and northern
Utah.
This will be the last Storm Summary issued by the Weather
Prediction Center for this event. Please refer to your local
National Weather service office for additional information.
