- Moisture associated with the remnants of Tropical Storm Rachel

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 possible across northern Utah.
