The Essex Region Conservation Authority has issued a flood warning.

The authority says a significant weather system is set to make its way over the province potentially dumping heavy rain on the region. That, combined with above-normal temperatures resulting in snowmelt, could lead to flooding.

CTV Meteorologist Gary Archibald says up to 20 mm of rain could fall by early Tuesday morning, with an additional 25 to 40 mm expected by Wednesday afternoon.

ERCA's Director of Watershed Management Tim Byrne says with the ground already saturated, precipitation falling in a fast rate will be converted to runoff and could result in flooding.

“The ground is frozen, so any rainfall is going to flow right off,” says Byrne. “It’s not going to be absorbed at all.”

The forecast has some homeowners in Windsor-Essex on edge, especially those who are still rebuilding after record breaking rainfall at the end of August.

South Windsor resident Kevin Williams tells CTV News he has already checked his sump pump in his basement, which is still being redone.

“Our basement isn't finished, so we get to test out all the new systems that we got put in place, before we pump in a lot more money down here,” says Williams.

Byrne recommends residents, especially those living in low-lying areas or flood-prone land, to do a little bit of spring cleaning.

“Debris around their yard that accumulates over winter, if it’s blocking or near drains, stand pipes, catch basins, clean it,” says Byrne.

The flood outlook is in effect until 9 a.m. on Wednesday.
