The combination of deep snow and inches of rain led to the flooding problems. As temperatures warmed above freezing, snow and ice starting melting, throw in moderate rain and it just elevates the situation.
With as deep as the snow was, a slow melt would have been ideal. But the rain helped accelerate the melting. Think of it this way, when the rain hits the snow pack it not only soaks it up like a sponge, but it also quickens the melting process. When the snow pack reaches saturation, it releases the water even quicker.
In more simpler terms, rain amounts ranged from two to three inches in southeast KELOLAND. That rain water combined with the water in the melting snow pack to lead to the flooding.
The blizzard in western, central, and northern KELOLAND dropped snow amounts of four to more than 12 inches. In time, this too will melt, but we need a slow melt.
