Jackson Mayor Chokwe Antar Lumumba urged residents to “get out now,” during a news conference Saturday.
Authorities earlier predicted the Pearl River to reach 36 feet and crest by Tuesday after record-setting rainfall in recent days, however the river is now expected to crest late Sunday through Monday evening before slowly lowering.
A flood stage is considered “major” at 26 feet. The current flood warning says dozens of additional streets in downtown Jackson will flood at 34 feet, with water close to entering homes in Northeast Jackson at 35.8 feet.
“We are expecting waters to begin to impact neighborhoods as early as Sunday evening,” Lumumba said, adding as many as 150 homes are expected to be affected by the flooding.
“The state of Mississippi is as prepared as possible for this flooding,” Reeves said. “My administration, including (Mississippi Emergency Management Agency), is monitoring this situation closely, and actively working to respond as quickly as possible to ongoing developments with flooding.”
Authorities are warning that communities affected by the flood in 2020 face a high probability of being impacted again. “Residents in those impacted areas should be ready to leave within 48 hours,” Lumumba said Saturday.
The mayor warned residents that flood waters may remain on the ground for several days, and residents should be prepared to be away from their homes for up to two weeks.
A flood warning remains in effect in parts of Mississippi, including in Jackson around the Pearl River, until further notice, the National Weather Service said.
In Ridgeland, Mississippi, just north of Jackson, residents who had to evacuate during 2020’s floods found themselves packing their bags again.
Mayor: Don’t put yourself in harm’s way
On Saturday morning, after heavy rainfall, the Pearl River Valley Water Supply District increased the discharge from Barnett Reservoir to 60,000 cubic feet per second, a move the district warned will put water on Jackson streets.
The threat of flooding will be limited to localized areas Sunday as slow-moving thunderstorms reform during the day, according to CNN Meteorologist Derek Van Dam. Scattered thundershowers could produce an additional 1-2 inches of rain by Sunday night, mainly south of Interstate 20.
Hot and humid conditions will persist, with highs in the middle to upper 80s.
Jackson’s mayor urged residents to stay away from flooded areas.
“We do not need sightseers, and we do not need you putting yourself or those that are helping with rescue efforts in harm’s way,” Lumumba said.
