Three tornado watches, highlighting a “particularly dangerous situation,” were issued for parts of Louisiana and Mississippi beginning early Tuesday afternoon and later in the afternoon into the evening hours — actually after midnight — along with two more tornado watches for parts of Mississippi and Alabama updates easternmost sections (see outlined area on map).
As of 8:30 p.m. CST, 15 tornadoes have been sighted, 13 of them in Mississippi. There were many reports of downed trees and power lines, significant damage apparently occurring in and south of Bassfield in south-central Mississippi, about halfway between Gulfport and Jackson, where a wedge tornado was sighted. There were 25 major hail and 15 wind damage reports in addition to the 15 tornado sightings for a total of 57 severe storm reports as of 8:30 p.m.
