Sunday was a historic day in Windsor in terms of the amount of rain the city received.

Environment Canada says Windsor saw a record-setting 42.2 mm of rain on Sunday alone, surpassing the old mark for April 15th of 31.2mm set in 1972.

Over the weekend a total 62mm of rain fell on the region.

Some areas saw flooding such as Chatham-Kent and Point Pelee National Park.

Point Pelee is closed so that officials can assess damage done by the flooding.

The Essex Region Conservation Authority has upgraded its Flood Watch issued Sunday night to a Flood Warning.

Officials are concerned about forecasted winds out of the west at 25 to 35 kilometers per hour with gusts exceeding 45 to 55 kilometers per hour.

Director of Watershed Management Services, Tim Byrne, says flooding hasn’t been this bad in the Cotterie Park area since 1998.

Byrne tells CTV News about a dozen homes are damaged from the weekend storm, and six to eight homes may be damaged beyond repair.

The Flood Warning is in effect for the municipality of Leamington, all areas west of Point Pelee National Park, and for the west coast shoreline areas of Pelee Island.

The West Shore Road of Pelee Island has been closed due to flooding, shoreline erosion and damaging waves. In the affected areas, portions of the travelled road surface and private lands are covered with water.

Roads have also been washed out between Kingsville and the Belcreft Beach area in Harrow.

Residents report flooding in the Cedar Island and Hillman Marsh area as well as in parts of Erieau in Chatham-Kent.

The weekend storm affected all of southern Ontario with tens of thousands still in the dark across the province.
