April 6-7, 2024 Windstorm

An intense storm system moved across northeast Colorado on April 6th and then moved northeast into central Nebraska on April 7th.  Strong and damaging winds occurred over portions of the mountains, foothills and northeast plains, from April 6th through April 7th, as the system moved across.   Wind gusts across the mountains and along and near the foothills ranged from 70 to 95 mph with a peak gust of 97 mph at the NCAR Mesa Lab.  Across the northeast plains, the strongest winds were focused along and north of a line from Denver to Fort Morgan to Akron.  Winds gusts from 60 to 80 mph were common.

There quite a few reports of downed trees, power poles and other minor damage where the highest winds occurred.  Up to 150,000 customers lost power during the peak of the event.  Most of these outages were in and around the Denver area.

Although strong winds can occur in April, as the graph shows below, only 17 documented events of winds exceeding 70 mph have occurred in Boulder since 1969, prior to the most recent event.
