Delayed warm weather increases threat of spring flooding

Posted: Updated:

The delayed arrival of warmer weather is bringing with it an increased threat of spring flooding.

The National Weather Service last week released its spring flooding outlook. It says that as the inevitable spring melt is delayed, it increases the likelihood of heavy spring rains and snow melt coming all at once, swelling rivers and streams. Experts say a higher amount of snow in the valleys and the frozen ground may compound the problem.

"The thing about the snowpack this year is that it's everywhere. We have almost as much snow down here as we do up in the mountains. We have 2 to 3 feet just about everywhere. So from the standpoint of the snow melt, that's a lot more area that has all that water that's ready to run off and we have about 5 to 10 inches of water equivalent in the snowpack," said Jamie Shanley, a United States Geological Survey hydrologist.

Shanely says the snowpack conditions right now are very similar to those in 2011, when spring rains in April and May caused flooding in Central Vermont and broke water level records in Lake Champlain.
