While the spring thaw will be a welcome change of weather in most of the country, there is a risk that snow melt and spring rains could lead to rivers exceeding flood levels. 
“The continuation of winter weather, above-average snowpack, frozen ground and thick ice coverage on streams and rivers will delay spring flooding into April in the upper Midwest eastward to New England.
The intensity of the flooding will depend on the rate of snow and ice melt, and future rainfall.
Continued well-below average temperatures this winter resulted in significant river ice formation and ice jams in locations further south than customary, flooding homes and businesses, and impacting river commerce.
There is also an elevated risk of more ice jams this spring in the northern tier of the U.S. from Montana eastward to northern New England.
‘This year’s spring flood potential is widespread and includes rivers in highly populated areas putting millions of Americans at risk,’ said Louis Uccellini, director, NOAA’s National Weather Service.
‘Although widespread major river flooding is not expected, an abrupt warming or heavy rainfall event could lead to isolated major flooding.'”
