(CNN)After record-setting rainfall this week, Jackson, Mississippi, is preparing for the Pearl River to reach 36 feet by Tuesday, leading to flooded streets.
Mayor Chokwe Antar Lumumba called for voluntary evacuations Thursday.

The river, which runs through the state capital, is expected to crest at 36 feet on Tuesday.
Residents recall downtown flooding in 2020 when it reached 36.7 feet.
Mississippi Emergency Management Agency Executive Director Stephen McCraney said emergency responders learned from that experience and have been planning for another flood.
"If you were impacted then, there's a good chance you'll be impacted now," he said, affiliate WAPT reported.
The National Weather Service illustrates here how the water level is rising, showing the crest is right at the major flood level stage.
The mayor said sandbags are being made available and shelters will open as they are needed.
This week, a slow-moving weather system drenched parts of the South, triggering flash floods that stranded residents, washed away roads, derailed a train, crept into homes and forced numerous rescues.
The Pearl River in Jackson, Mississippi is under a flood warning.
The weather service issued a flash flood emergency Wednesday for nearly 300,000 people in Jackson and nearby communities.
On Thursday morning, the Pearl River Valley Water Supply District increased the discharge from Barnett Reservoir, a move the district warned would put water on Jackson streets.
"We are calling for voluntary evacuation to take place over the course of this time in the areas that are expected to be affected," the mayor said. "We expect somewhere by Monday into Tuesday, many neighborhoods will be impacted."
"I think it is important that our residents prepare in advance," he continued. "If we instruct you that you are in a risk area, high risk area, please heed that advice.
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.
The warning says, "Forecast includes rainfall on the ground and 24 hours of additional rainfall."
For Friday, a flood watch in the region
On Friday, a flood watch stretches along southern Mississippi into Alabama and the far western panhandle of Florida through the afternoon. Included are Pensacola, Florida; Mobile, Alabama; and Hattiesburg and Natchez, Mississippi.
Jackson is north of Friday's flood watch. But the Pearl River flowing through it is under a flood warning as water continues to run off from this week's rain. The river is at moderate flood stage Friday morning.
A slight risk of excessive rainfall exists Friday from eastern Louisiana to the Florida panhandle as slow moving showers and thunderstorms meander across the region. An additional 2 to 4 inches could fall in spots, leading to increased flood concerns. Areas that have recently experienced flooding are at greatest risk as rivers and streams remain swollen by this week's deluge.
Minor to moderate river flooding is forecast to continue across central and southern Mississippi through the weekend. Low-lying and flood-prone areas will remain vulnerable.
