The National Weather Service in St. Louis has issued a high wind advisory from midnight to 6am Tuesday. Strong and gusty northwest winds are expected to move in overnight, and could create areas of blowing snow, resulting in brief periods of low visibility. A wind advisory is issued when sustained winds are forecast to be 30 to 39mph or gusts that will range between 45 and 59mph.
In this case, winds are expected to be sustained at 20 – 30mph with gusts of up to 45mph. Motorists traveling on west to east oriented roadways will experience strong cross winds. Motorists in high profile vehicles should use extra caution until the winds subside, and lightweight outdoor objects will be blown around. Winds of these magnitudes may cause minor property damage without extra precautions. Those responsible for construction sites should be certain that all building materials are secured and structures are properly braced.
