Latest update from Accuweather regarding Red River and Mississippi River flooding:
The Red River will continue to be an area of concern this season, as the northern Plains began spring with high levels of water in their snowpack and have not had much reprieve from continual snowfall. Andrews says that everything will be determined by how the snow melts.
"There's the potential for it to go quietly," he said. "If they see warm days and cool nights with little extra precipitation, flooding will still occur, but it would be slow and not catastrophic. If they see frequent warm rains, that's going to lead to problems."
For the next week, they can anticipate temperatures staying low enough to avoid rapid melting risks, but following the recent record-level snowfalls when temperatures do warm they will need to be monitored closely. Currently, the Red River's major flood warning for is for two locations on one of its tributaries, North Dakota's Devil Lake.
Since the area is no stranger to flood risks, they do have a contingency plan. Flooding on the Red River tends to be slow, which is good for allowing time to evacuate areas and implement plans. It does have a down side, however, as the slow flooding is also slow to recede.
One of the main areas for concern for flooding will be the city of Fargo. At 19 feet, the dam will flood. By 23.3 feet, the North Broadway Bridge floods as well. At 30 feet, they reach major flood stage and streets begin to close. As part of their ongoing flood control projects, they activate pump stations, starting when the river reaches its action stage at 17.7 feet. As needed, they will also move to build sandbag levees. At this time, the river sits at 15.8 feet at Fargo.
Meanwhile, parts of the Mississippi River are approaching flood levels, and with more rain set to move in, they may reach it in days. Areas near Dubuque, Iowa, are expected to crest Friday into Saturday. Currently, the river at this location has reached 14.25 feet. Its action stage is 15 feet, with 17 feet being a moderate flood stage.
Depending on how quickly the river floods to the north will affect how it floods farther down stream. If the slow-moving river floods at high levels in Dubuque, it may take weeks instead of days for flooding to move down to St. Louis, where flood levels are only 5 feet away.
Last year, with its incredibly low snow amounts, there was significantly less flooding across the country. This year it will be critical for areas that are prone to flooding to monitor their rivers and be prepared to quickly begin their emergency plans.
