Impacts

Strong crosswinds will affect travel for high profile and light-weight vehicles, including Interstates 80 and 15. Wind sensitive operations will be impacted.

Take the opportunity to secure loose items before the winds arrive Tuesday. Visibilities may be reduced in areas of blowing dust. In addition, winds will cause rough choppy waters on area lakes. Small boats will be especially prone to capsizing.

Those traveling through the southern mountains should plan for very strong winds, especially in the vicinity of Brian Head and Boulder Mountain.

Precautionary and preparedness actions

A high wind warning means a hazardous high wind event is expected or is occurring. Sustained wind speeds of at least 40 mph or gusts of 58 mph or more can lead to property damage.

Vehicles, especially high profile vehicles, can be difficult to control at times in high winds. Motorists should take extra caution, especially while crossing bridges, overpasses and un-sheltered areas.

The strong winds will create dangerous boating conditions on area lakes. These winds will create very choppy water and generate large waves which could capsize or swamp small craft. For your personal safety, operators of small craft are urged to postpone their outings until the winds subside.
