A slow moving storm system over the central United States produced another few rounds of thunderstorms with severe weather and flooding rains. Significant flooding occurred over portions of central and northern Mississippi, with many homes and roads flooded across the region.

Flash Flood — Jun 8, 2021

As an upper-level low pressure system moved over central parts of the country, a few storm systems moved across the state of Mississippi.

Over 200 homes were flooded in portions of Bolivar and Sunflower Counties.
