This month, the National Weather Service Tucson is celebrating 25 years at the Dennis DeConcini Environment and Natural Resources Building at the University of Arizona.

NWS Tucson co-located with the United States Geological Survey (USGS) to the campus building when it opened in 1997 from its original location at the Tucson International Airport. 

To mark to occasion, NWS  put together an interactive Story Map  counting down the top weather events over the past 25 years, from record floods to snow to wildfires. Check it out, here!
