...Serious flooding situation continues to evolve across southeast
Missouri and southern Illinois...
...FLASH FLOOD WATCH REMAINS IN EFFECT THROUGH LATE TONIGHT...
The Flash Flood Watch continues for
* Portions of southern Illinois, southwest Indiana, western
Kentucky, and southeast Missouri, including the following
areas, in southern Illinois, Alexander, Edwards, Franklin,
Gallatin, Hamilton, Hardin, Jackson, Jefferson, Johnson,
Massac, Perry IL, Pope, Pulaski, Saline, Union, Wabash, Wayne
IL, White, and Williamson. In southwest Indiana, Gibson, Pike,
Posey, Spencer, Vanderburgh, and Warrick. In western Kentucky,
Ballard, Carlisle, Daviess, Fulton, Henderson, Hickman,
McCracken, and Union KY. In southeast Missouri, Bollinger,
Butler, Cape Girardeau, Carter, Mississippi, New Madrid, Perry
MO, Ripley, Scott, Stoddard, and Wayne MO.
* Through late tonight
* The Flash Flood Watch remains in effect for all of southeastern
Missouri, southern Illinois, southwestern Indiana, and a few
border counties of Western Kentucky along the Ohio and
Mississippi Rivers. Another thunderstorm complex early this
morning is dumping heavy rain across the watch area, which is
worsening flooding conditions. Significant additional rainfall
is likely today, which could produce locally life-threatening
flash flooding. The Current River in the Ozark foothills of
southeast Missouri is forecast to reach a record flood crest
today. Five to nine inches of rain have already fallen over
parts of the watch area in the past couple days, and an
additional couple of inches are expected to occur before the
storm system exits the area tonight. Again, the heaviest
rainfall is expected in the Missouri Ozark Foothills. Locally
higher amounts are also possible where numerous thunderstorms
move across the same area.
* In addition to flash flooding of roadways and streams, the heavy
rainfall is expected to cause further rises on many of the area
rivers, particularly the smaller rivers in southeast Missouri,
such as the Saint Francis, Black, and Current Rivers. Given the
widespread rainfall across the region, other larger river
systems, such as the Mississippi and Ohio Rivers will see rises
in water levels occur in early May. Due to the prolonged period
of rain, some of the flash flood warnings that are issued may be
converted to areal flood warnings after the rain diminishes.
A Flash Flood Watch means that conditions may develop that lead
to flash flooding. Flash flooding is a very dangerous situation.
You should monitor later forecasts and be prepared to take action
once Flash Flood Warnings are issued.
