Heavy rainfall amounts of 2 to 3+ inches led to flooding issues across portions of southern Illinois and southeast Missouri. Numerous Flood Advisories were in effect throughout this event. A water rescue was performed in Hamilton County, Illinois on the morning of the 9th. During the evening on February 8th, a few thunderstorms developed that produced strong winds.
