Environment Canada says there's more rain on the way this week and with the ground already wet there could be flooding.
The weather agency issued, on Wednesday morning, a special weather statement for Hamilton and much of Southern Ontario.
It says that with wet weather set to return later in the week and with the ground already saturated, there may be flooding.
Environment Canada says "rain will spread back into Southern Ontario from the southwest Thursday reaching Eastern Ontario by Friday morning."
The agency expects total rainfall amounts may approach 50 mm in some areas by the weekend.
On Monday the city issued its own flooding warnings and offered these tips to avoid flooding:
- Keep catch basins in front of your home clear of leaves and debris.
- If your home has a backwater valve installed, follow the manufacturer's instructions for cleaning to ensure that it is functioning properly.
- Check your sump pump to make sure it's working properly.
- If your home is prone to flooding, consider ensuring any valuables are up off of basement floors.
- Keep your eaves troughs clean. When your eaves troughs are blocked, the rain will pour over the edges and land on the ground next to your home. If you have cracks in the concrete wall of your basement, or problems with your weeping tile, this water could enter your home.
This comes after an April 20 rainstorm flooded parts of Hamilton — especially Dundas. The city declared it a disaster to unlock thousands in potential compassionate grants for homeowners who suffered water damage.
