Some rough weather will hit the Greater Toronto Area on Wednesday afternoon and evening with very high winds and heavy rain expected to continue overnight.

Environment Canada has issued a heavy rainfall warning for Toronto, with up to 50 millimetres expected by Thursday morning.

The storm will also bring strong winds, with gusts up to 70 kilometres an hour possible.

CBC Meteorologist Johanna Wagstaffe is tracking the storm that began Wednesday morning with a few showers. She said most of the rain will hit Wednesday evening and overnight into Thursday.

"The heavy stuff is still to come," said Wagstaffe just before 12 noon on Wednesday. "And those winds are starting to pick up. We have a rainfall warning from Windsor through to the Greater Toronto Area up towards Parry Sound. At least 50 millimeters are on tap and Windsor, Sarnia, shores of Lake Erie ...  I think you’ll see closer to 60-70 millimeters of rain over the next 24 hours.

"Tomorrow we’ll start to see the rain taper off to showers for southern Ontario."

Travellers headed to the eastern United States — particularly New York, New Jersey or Philadelphia — should be aware those areas are expecting very high winds, heavy and the possibility of flash flooding.
