Authorities have not identified the girl. She was last seen wearing a pink dress and tennis shoes.
Yazoo County Director of Emergency Management Joey Ward said emergency crews, a dive team and volunteers searched rain-swollen drainage ditches until about midnight Sunday. The search resumed Monday.
National Weather Service meteorologist Daniel Lamb said the Yazoo City area had received nearly 7 inches of rain in the past two days. He said other areas had as much as 5 inches.
Ward said the search focused on the drainage ditches that connect to a canal that runs through Yazoo City.
He said the girl was reported missing about 7 p.m. Sunday and was believed to have been caught up in flood waters outside the back door of her parents’ house.
On Monday afternoon, Mississippi Department of Transportation officials reported parts of U.S. Highway 49 south of Jackson were closed in Simpson County due to flooding near Dabbs Creek.
Traffic was backed up on Highway 49 between D’Lo and Braxton after high water forced transportation officials to close the road. Sunday’s incessant rain pushed Dabbs Creek above its banks and floodwater rushed onto the highway.
“We’ve just shut down northbound Highway 49 and we’re fixing to shut the southbound side down. We’ve got flooding from here into D’Lo. We’ve already started evacuations there in D’Lo,” said Glen Jennings of the Simpson County EOC.
Traffic was being rerouted.
Businesses along Highway 49 in Richland were forced to park vehicles on higher ground because many parking lots were flooded.
Elsewhere, damage was being assessed in Covington County in south Mississippi where the Mississippi Emergency Management Agency said a possible tornado damaged homes. The agency said at least seven minor injuries were reported. Wind damage also was reported in Neshoba County.
A flood warning was in effect until late Monday in low-lying areas of eastern Mississippi.
In Warren County, Sheriff Martin Pace said a dam on private property broke Sunday in the Bovina area off Interstate. 20. Pace said the water covered portions of Warriors Trail. He said no homes were in danger.
Byram residents in the Robinson Estates also experienced some flooding. Residents had to park their vehicles at the entrance of the subdivision.
The National Weather Service issued a flood warning for the Pearl River, which is expected to crest at 32.5 feet on Thursday afternoon in the Jackson area, said meteorologist Ed Tarver.
At its highest projected point, the Pearl would be more than 4 feet above its flood stage, he said, adding at that point it’s considered minor flooding.
Tarver said there’s a 70 percent chance for another round of showers and thunderstorms to hit the Jackson area on Tuesday.
