Hurricane Melissa produced the fastest hurricane winds to be recorded by a dropsonde, verified by reviewing data at NSF NCAR! Hurricane Melissa’s 252 mph wind gust surpassed the previous record from Typhoon Megi over the Western Pacific in 2010, where a dropsonde measured wind gusts of 248 mph.

Let’s explore the NSF NCAR Timeline! In 1961, NCAR found its forever home in Boulder, CO, on Table Mesa. After a vote by Boulder residents in favor of the site, the land on Table Mesa was donated to the NSF by the State of Colorado. https://www.archives.ucar.edu/exhibits/ncar-timeline
