An unusually high amount of snowfall, combined with an anamolously cold April set the precedent conditions for an impactful break up season. Ice was thicker across the rivers than it had been for several years. A rapid warm up across Interior Alaska caused upstream snow melting, leading to ice jams and widespread flooding along the lower Kuskokwim River.
