Impacts
Gusty winds could knock down tree limbs and blow around unsecured objects. Minor damage to outdoor objects is possible. Locations impacted include...

This will lead to a sudden increase in waves and very choppy waters which will result in hazardous boating conditions. Boaters are urged to seek safe harbor if possible. This includes Interstate 80 in Utah between mile markers 89 and 92, and between mile markers 101 and 109.
