The wider storm

A strong upper level storm system took up residence in the northern Gulf of Alaska during the second weekend of April. Abundant moisture was drawn up by the circulation of this system which managed to wrap around the storm center and push into the Interior of Alaska. This resulted in 24 to 36 hours of steady, and at times heavy, snowfall that affected travel along Interior highways.
