* ADDITIONAL DETAILS...
- Moisture associated with the remnants of Tropical Storm Rachel
will continue to spread into northern Utah 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 possible across northern Utah.
