Explore projected maximum precipitation events across Alaska

SNAP collaborated with the Alaska Department of Transportation to develop a point precipitation frequency tool using state-of-the-art climate projections to better understand the future of precipitation trends across Alaska. This is critical to maintaining transportation infrastructure across the state, and in designing new projects to be resilient to a changing climate.

This tool was developed from data provided by the National Weather Service Atlas 14 system and climatological forecast data generated by Peter Bieniek of the University of Alaska Fairbanks.
