The snowpack has expanded in all bowls attributable to a lot wetter than ordinary April, with most stations recording great better than expected precipitation that fell as snow. The north and west of the territory experienced significantly lower average monthly temperatures than usual in April. Colder temperatures and cloudier than typical circumstances eased back snowmelt, especially at higher height.

The likelihood of a shorter freshet period is increased by the increased snowpack and delayed snowmelt. This does raise the risk of flooding, but the risk is lower on larger rivers like the Yukon River, where it is mostly higher in small to medium-sized rivers. Although peak freshet flood risk to Yukon communities on large lakes and rivers remains low, water levels are anticipated to be above average. When compared to the historical peak snowpack, the current snowpack provides a better understanding of flood risk and more closely matches the April 1 snow survey.

During the spring breakup and snowmelt period, a high snowpack is one of several risk factors that influence the potential for flooding. Spring climate, the timing and movement of snowmelt, as well as spring precipitation occasions, are likewise significant drivers of flooding paying little heed to snowpack levels.
