Fast-melting snowpacks cause flooding

Area-wide snowpacks continued to build throughout the month of April. With warmer temperatures, low elevation snowpacks are starting to melt. High elevation snowpacks have not melted much yet. Usually, high elevation snowpacks start to melt by April 11.

Spring is a month behind normal. This could be concerning if all snowpacks melt at the same time. If we start to lose an inch or more per day at our Snotel sites, overland flooding could become serious.
