The town of Princeville in Edgecombe County issued a mandatory evacuation order on Sunday after flooding from Hurricane Matthew, officials said.

“The Princeville Board of Commissioners issued a mandatory evacuation for all citizens due to potential flooding and a 7 p.m. curfew has been set,” town officials said.

More than 450 Princeville residents were living in Red Cross emergency shelters Monday afternoon and they're expecting more by the end of the week.

The Tar River crests at 32 feet and officials are worried that the dykes, that hold 37 feet of water, cannot handle the water Hurricane Matthew dumped on the small town.

The Edgecombe Sheriff's Office set up an Emergency Operations Center to monitor water levels. They are in contact with state officials in Raleigh and have swift water rescue crews on standby if the river floods.

The town was completely under water in 1999 after Hurricane Floyd dumped a lot of rain and a dam breach. WFMY News 2's Erica Stapleton talked to people in the town last week about their memories from that flood.
