The National Weather Service (NWS) has issued a Flash Flood Watch until late tonight to include portions of Mid-Missouri, mainly in counties south of the Missouri River.

Areas under the watch include Camden, Cole, Gasconade, Maries, Miller, Moniteau, Morgan and Osage counties and the cities of Jefferson City, Osage Beach, California and Linn. The total Flash Flood Watch area extends from Joplin and Springfield in southwest Missouri, through the Lake of the Ozarks area in central Missouri, to St. Louis in east-central Missouri.

According to the NWS, thunderstorms capable of producing very heavy rainfall in a short period of time are expected to move across the region, mainly along and south of Interstate 70, this afternoon into this evening.

One to three inches of rainfall over already wet ground will likely produce flash flooding. Heavy rainfall will result in flooding of low lying or poor drainage areas and ultimately dangerous flash flooding on smaller creeks and streams. Additional rises on larger streams and rivers will also be possible.

A Flash Flood Watch is advanced notice that conditions are favorable that may lead to flash flooding. People in the watch area, especially in flood prone areas, should use this time to make preparations just in case. Stay informed, and be ready for quick action if flooding is observed or if a Flash Flood Warning is issued.
