The Town of Sussex sent out an emergency alert to residents this morning saying that flooding is occurring in the town.
A reception centre as been set up at Kingswood University on Welsey Road for affected residents.
Several roads throughout the province are experiencing flooding, and you can find the full list here.
Environment Canada meteorologist Darin Borgel says more than 50 millimetres of rain had already fallen in some areas as of early Saturday morning.
"During the day, the temperature is going to drop quite markedly in the Saint John area," says Borgel. "It's going to go down to about +2 or +3 this afternoon and then continue to fall well below zero overnight tonight."
The national weather agency has issued a flash freeze warning for much of the province, and Borgel says the sudden drop in temperature could lead to slippery conditions on roads and sidewalks.
