Storms move across Mid-Missouri, trigger flooding

Storms move across Mid-Missouri, trigger flooding

May 21st, 2019 in Local News

This National Weather Service graphic warns of an enhanced possibility of severe thunderstorms developing throughout Mid-Missouri during the afternoon and evening hours of Tuesday, May 21, 2019.

 

Locally heavy rainfall from storms moved eastward across Missouri Tuesday afternoon, increasing flood risk throughout much of the state and raising Missouri River levels, according to the National Weather Service (NWS).

A Tornado Watch was issued for much of Mid-Missouri. The watch was set to expire at 7 p.m. for Camden, Maries, Miller and Morgan counties, and expire at 10 p.m. for Boone, Callaway, Cole, Gasconade, Moniteau and Osage counties. 

A Flash Flood Watch continues for Mid-Missouri. Heavy rainfall will result in flooding of low lying or poor drainage areas and ultimately dangerous flash flooding on smaller creeks and streams. Significant rises on larger streams and rivers will also be possible.

In addition, the forecast for flooding has changed from moderate to major severity along the Missouri River at Boonville, Jefferson City, Chamois, Gasconade, Hermann, Washington and St. Charles, as well as the Osage River near Mari-Osa Campground. River forecasts are based on observed precipitation and forecast precipitation for the next 24 hours. 

The NWS advises rainfall heavier than forecast could cause river levels to rise even higher than predicted, and warns motorists to never drive cars, trucks or sport utility vehicles through flooded areas. The water may be too deep or current too strong to allow for safe passage.

A Flood Warning continues for the Missouri River at Jefferson City. At 1 p.m. today, the stage was 25.55 feet, up from 24.89 feet at 8 a.m. Flood stage is 23.0 feet. Major flooding is forecast. The river is forecast to crest near 32.7 feet Thursday afternoon. (Use the links below for updates and other area river stages, weather information and utility outages.)

The NWS lists the following impacts at various river stages based on historical observations:

* Impact: At 32.0 feet...Highway 179 at Marion, northwest of Jefferson City, floods.
