Spring Breakup: Alaska Rivers at Risk of Ice Jam Flooding

0:00Anchorage store is making news on March 18. The National Weather Service issued its first spring break-up forecast, highlighting risks of ice-jam flooding along the upper Yukon and Tanana rivers. In Alaska, heavy snowpack on thick, rough river ice is setting up potential trouble as warmer weather approaches. A stubborn coal pattern with northerly winds is keeping temperatures below average, likely holding steady until late this month. Officials note that a slow break-up over about six weeks would be ideal to avoid major issues. The real worry comes if spring warms up fast after this chill, especially in May, that could send big water volumes crashing into strong ice, causing jams at river bins and leading to downstream flooding for communities. Last year, similar setup triggered widespread flooding on the Inaco River, and upstream conditions could impact lower Yukon areas again.
