Snow load data

Ground snow load by state

Per-state summaries of the federal ERDC/CRREL SR-20-1 station dataset: 49 states and 15,104 measurement stations. Each page shows the range of estimated 50-year ground snow loads, the stations with the highest estimates, and how to get a site-specific estimate for an address. (Hawaii has no ground snow load and is not part of the dataset.)
