YAZOO CITY UNDER THE GUN
In Mississippi, very damaging winds and a possible tornado are impacting the area around Yazoo City. There has certainly had a bad run of luck there over the past few years. From Alan Gerard: Yazoo County reporting “heavy damage” NW of Yazoo City in Lake City and Deerfield Road areas. don’t know any more details than that. Could just be lots of trees, could be structures. Will advise when we know more.
This storm could end up impacting Sumter County a little after 1 a.m.
TORNADO REPORT
2 NE Shelby [Bolivar Co, MS] emergency mngr reports TORNADO at 09:08 PM CDT — heavy damage along blue cane rd…3 structures damaged with one home off its blocks along with the roof removed. power lines down and power poles snapped.
This is for the storm that is near Grenada now.
