The Grand River Conservation Authority has upgraded a flood warning for parts of the Grand River watershed, to a flood warning for the entire watershed.

GRCA issued a flood warning to a number of townships, including Woolwich, Wilmot and the City of Cambridge.

In a special weather statement from Environment Canada, 10 to 20 millimetres of rain could fall by Tuesday along with record-breaking temperatures, typically seen in April, which is expected to cause significant runoff into the river system.

GRCA said the current weather system is expected to affect the watershed Monday through Wednesday as an additional 5 to 10 millimetres of rain is expected to fall Wednesday.

"Rainfall totals of 40-50 millimetres are expected across the watershed," GRCA said in a release.

"Ice jams currently in place in the Grand River through the City of Kitchener, the City of Cambridge, City of Brantford and community of Cayuga have a high potential of causing additional flooding."

As a result, GRCA has issued a flood warning townships and cities:

  • Town of Grand Valley: Waldemar
  • Township of Mapleton: Drayton
  • Township of Woolwich: St. Jacobs
  • City of Cambridge
  • Township of Wilmot: New Hamburg  and Ayr
  • City of Brantford
  • Town of Cayuga
  • Town of Dunnville: Port Maitland
