Overview
|
A significant rain event occurred late Friday into Saturday across northeast Missouri, extreme southeast Iowa, and west central Illinois which resulted in flash flooding and a rapid rise on the Fox River near Wayland, Missouri. A slow moving mesoscale convective vortex (MCV) tracked over the area and brought very heavy rain in a short amount of time. Rainfall amounts between 4 and 8 inches fell in less than 6 hours which caused many stalled vehicles and several water rescues in the towns of Kahoka, Missouri and Keokuk, Iowa. A culvert was washed out south of Kahoka and many secondary roads had water over them. Other towns that received heavy rain were Fort Madison, Iowa and Burlington, Iowa. |
