Colorado Wind Reports – March 6, 2017

A downslope windstorm impacted the Front Range and eastern plains of Colorado on Monday, March 6th, following a Pacific cold front that moved through the area.  This type of event is known as a “Bora wind event”, which differs from a Chinook wind event in that prevailing wind directions are from the northwest and temperatures are colder (given that it follows a cold front) than the typical warm temperatures associated with Chinook winds.  Also, Bora winds tend to spread farther out onto the plains whereas the strongest Chinook winds are usually concentrated near the foothills.  During bora wind events, the higher elevations along the Continental Divide often receive periods of heavy snow, while areas east of the Divide along the I-25 corridor remain mostly dry due to the downsloping nature of the winds.  Given the dry conditions that have developed over the past several months east of the Continental Divide, fire danger remains especially elevated during these high wind events.  Here are some of the peak gusts reported across central and eastern Colorado on March 6th from NWS spotters.
