Every year since the mid 1990s the annual spring thaw in the central US has resulted in more catastrophic flooding. With this past winter’s heavy snows, expect more severe spring flooding along the Mississippi river delta, the Missouri River and other inland water ways.

Eventually the interior plains of the central USA may in fact, be under water.

Below are several projected “earth changes” post-flood maps showing what the United States might look like in 10, 20 or 30 years from now. Relocations may be necessary for millions who live in the interior regions affected by increasingly disastrous spring flooding seasons.

A break in the current cold weather pattern is likely approaching for the Plains, Midwest and Northeast. But with a rough winter piling on feet of snow across the United States, will flooding be a problem?

The jet stream is anticipated to retreat toward the U.S./Canadian borderbringing warmer temperatures to the northern portion of the United States.

“The change is expected to begin this weekend over the West and Plains and should translate into the East next week,” said AccuWeather.com Expert Senior Meteorologist Alex Sosnowski.

In fact, AccuWeather.com Expert Long Range Forecaster Joe Bastardi is forecasting a 70-degree day in Washington, D.C., and an 80-degree day in Dallas before the month ends.

This anticipated warm-up, however, could be hazardous for people living in low-lying areas or near rivers and streams, especially where a large amount of snow has accumulated.

Areas of the Northeast, including parts of western Massachusetts and Upstate New York, could have flooding problems, said AccuWeather.com Expert Senior Meteorologist Elliot Abrams.

This image courtesy of NOHRSC, shows the current snow/water equivalent as of Feb. 7. Areas ranging from purple to pink have between 2 and 10 inches of liquid.

For example, undisturbed areas around Worcester, Mass., are under about 4 feet of snow, which could equal as much as 4-5 inches of liquid, Abrams said.

AccuWeather.com Senior Meteorologist Dave Dombek added that areas of Connecticut, northwestern Pennsylvania, and even parts of the Appalachians and Midwest could also be at risk due to their deep snowpacks.

The usual conversion is 10 inches of snow equals an inch of liquid, but Abrams said with melting and refreezing occurring, there could be higher amounts of liquid in the snowpacks.

Temperatures above freezing do melt snow, but in order for significant melting to occur, there needs to be several days of highs in at least the 40s.

In addition, while warmer temperatures can cause flooding, a much bigger threat is when the warm-up comes with significant rainfall.

“Temperatures in the 50s or higher combined with heavy rain is the biggest danger,” Abrams said.

Ice jams are also a concern. As ice on a stream breaks up, it could accumulate farther downstream, creating a blockage. Water behind the ice jam can then overflow the banks of the stream, leading to flooding.
