Historic and life threatening heavy rain and flood event continues. There have been at least 11 fatalities in the flooding in Missouri and Illinois from drivers who drove into flooded roadways. This is an incredibly dangerous and life threatening situation with a STATE OF EMERGENCY now declared in Missouri and in St. Louis County.
Rainfall totals so far have ranged from 4" to 8" in a band along and north of I-70 in Illinois stretching back to along I-44 in Missouri. Southeast of STL in southern Illinois and far southeast MO amounts have been in the 1" to 4" range.
Additional heavy rain is like tonight along with embedded thunderstorms. An additional 2" to 4" is likely across the entire region pushing storm totals to 6" to 12" across the heart of our viewing area.
Very serious flash flooding is likely to get re-invigorated overnight and continue well into Monday. MoDOT already reports at least 180 roads closed with countless closures in Illinois.
Of the many, here are several that standout I-70 is now closed in both directions near St. Peters due to the flooded Dardenne Creek. Hwy 141 will be closed under I-44 due to Meramec River flooding with up to 4 ft of water expected there. The flood gates will be closed to protect Valley Park which will have the effect of cutting off all other access to the city except from the north on Hwy 141. I can't even begin to cover the road closures in St. Charles and other counties. And because it is impossible to put up barricades at every location people could easily just drive into flooded roads and not know what hit them.
St. Louis has now set the record for the wettest year and the wettest single day ever in December. River crests on the Mississippi River from Grafton south through St. Louis are forecast to be the 2nd highest since 1993 with a full blown record crest expected down in Chester forecast right to the top of most of the protective levees in that region.
Crests on the Meramec are also forecast to flirt with record levels....with Arnold, Valley Park and Pacific expecting the #2 crest in history.
There really isn't much more to add as we wait for this truly biblical weather system to finish its strike on Missouri and Illinois. Behind the system much colder more December like air will great the sandbaggers and rescue crews. I cannot imagine a more unpleasant situation.
Also, not to be forgotten, there is a chance for light snow or flurries Wednesday that could result in a light coating of snow in some areas.
