While flooding problems will continue over parts of the South and Midwest, rain and melting snow may trigger flooding in part of the central Appalachians and mid-Atlantic region this weekend.

The expanding flooding risk will be caused by a major storm set to produce high winds, blizzard conditions and tornadoes this weekend.

Wet conditions since late last summer and heavy rainfall in recent days will keep rivers high and out of their banks from the lower Mississippi to the Tennessee and Ohio river basins this weekend and beyond.

Near where the Ohio flows into the Mississippi at Cairo, Ill. water levels are forecast to crest at major flood stage.

Farther south, along the Mississippi River at Osceola, Arkansas, major flooding is forecast that may prompt some evacuations later this weekend and into next week.

Meanwhile, the Big Nance Creek, that feeds into the Tennessee River in northern Alabama, is also forecast to reach major flood stage this weekend.

Many other tributaries and portions of major rivers in the region will reach moderate flood stage in the coming days.

In addition to stream and river flooding, additional rain into this weekend will be enough to cause urban flooding from northeastern Texas and central Louisiana to southern Indiana, southern Ohio and southwestern West Virginia.

Meanwhile, in part of the Northeast, there is also the risk of flooding this weekend.

"Snow and ice on the ground contain a significant amount of moisture in the central Appalachians to part of the Atlantic coast," according to AccuWeather Senior Meteorologist Brett Anderson.

There is up to a few inches of rain locked up in the snow cover. With the likelihood of an inch of rain and the potential for 2 inches of rain to fall, the equivalent of 3-6 inches of rain may be unleashed on some watersheds.

"As temperatures climb into the 40s and 50s with perhaps an inch of rain this weekend, quick runoff can lead to the quick flooding of small streams and significant rises on some of the major rivers," Anderson said.

This risk extends from eastern and northern West Virginia and much of Virginia northward to southern New York state, New Jersey and part of southern New England.

In all cases from the South to the Northeast, where secondary roads exist in low-lying areas near streams and rivers, flooding can occur this weekend.

Locations prone to flooding in the spring should be on the lookout for rising waters.

Debris that may have become lodged underneath small bridges should be removed by officials in a timely manner to allow the water to pass through with few obstructions as this event unfolds.

Never attempt to drive through flooded roadways no matter how shallow the water may seem. The water may be much deeper than it appears and the road surface beneath the water may have been washed out.

In the wake of this storm, a break from heavy rainfall is forecast in central and northern areas. However, downpours may continue to pester areas in the South Central and Southeastern states into early March.

National Weather Service hydrologists in the mid-Atlantic region have described the long-term flood potential for the rest of the winter and spring as above normal.

AccuWeather's long-range team of meteorologists expect flooding to remain a periodic problem well into the spring over the South Central and Midwest region thanks to more rain and runoff from melting snow to the north.
