Tim Marshall Inducted into the National Storm Chaser Hall of Fame
On February 15, 2025, Tim Marshall was honored as one of the inaugural inductees into the National Storm Chaser Hall of Fame, recognizing his lasting contributions to storm chasing and meteorology.
A forensic engineer and meteorologist at Haag since 1983, Tim has made significant advancements in the field of damage assessment. He was a principal developer of the Enhanced Fujita (EF) Scale, which the National Weather Service has used since 2007 to rate tornado severity. Tim remains an active member of the EF Scale committee and continues to advance wind and storm damage assessment through his work on a joint ASCE/SEI/AMS standard for wind speed estimation in tornadoes and severe wind events.
Beyond his technical contributions, Tim is a passionate educator and speaker. Over the past three decades, he has delivered hundreds of lectures on storm damage at meteorological and engineering conferences. His expertise has also been featured on National Geographic, Discovery Channel, NPR, Univision/NBC, CBS, and many other media outlets.
Congratulations to Tim Marshall on this well-deserved recognition!
