Major River Flooding
There has been some major river flooding ongoing across the Ohio Valley thanks to extreme rainfall over the past 5 to 7 days. Thanks to @NWSLouisville for the flooding picture out of Louisville, KY, where the Ohio River reached moderate flood stage last week and may not fall below that mark until this Friday! Interestingly, the Ohio River in Louisville (McAlpine Upper reached a crest of 35.64ft, on Monday afternoon, which is the 10th highest crest this river gauge has ever reached!
Major River Flooding
According to NOAA, there were 242 river gauges in flood stage as of Tuesday morning, 13 of which where at Major flood statge!
WOW! How about those numbers! A corridor of heavy precipitation this month helped push February precipitation numbers into Double digits for a number of locations! In fact, there was so much precipitation that Louisville, KY and Evansville, IN have seen their wettest February on record!!
