After an unusually cold spring, forecasters are cautioning that this year’s breakup of Alaska’s major rivers pose a heightened risk of flooding for dozens of communities along the riverbanks.
In May 2022, an ice jam about 12 miles downriver from Manley Hot Springs on the Tanana River caused significant flooding in the community.
The increased flood risk is due to two major factors: above-average snowpack and below-average temperatures in April throughout most of the state, which together have delayed melting and increased the risk of a more dynamic breakup, Van Breukelen explained.The Tanana River from Salcha up to Tanacross has broken up, according to a breakup report updated Tuesday. But most of the major rivers are still coated with ice.
