Talk about weird weather.

Environment Canada has issued a rainfall warning for most of southern Ontario, including Hamilton. The weather service estimated up to 50 mm of rain.

But on Thursday afternoon, it snowed instead. And according to Hamiltonians on Twitter, there was thunder too.

Environment Canada is still warning of rain and major snow melt. Here are some tips to prepare for flooding:

Here are some tips to prepare for flooding:

  • Clear all culverts, catch basins and watercourses to make sure water can flow freely. Make sure there’s no snow, trees, garbage or other debris blocking them. 
  • Clear fire hydrants around your house.
  • If your home has a backwater valve installed on the sewer, follow the manufacturer's instructions for cleaning to make sure it's functioning properly. Make sure your sump pump is working too.
  • If your home is prone to flooding, get valuable items off the basement floor.
  • Clean your eaves troughs. When they're blocked, rain will pour over the edges and could spill into your basement.
  • Stay away from fast-flowing streams and ponds, and stay off the ice. Higher temperatures will weaken it this week.
  • If you see a flooded area, don’t go near it. Don’t try to drive your car or walk through it.

  • Stay away from areas known to flood.
  • If you see a flooded road, call the city at 546-CITY to report it.
