Environment Canada has issued a special weather statement for Toronto and the GTA calling for up to 30 millimetres of rain on Thursday.

However, if the region receives just a few millimetres more than that rainfall amount, it could break a 64-year-old record set on this date in 1953, which was 34.3 millimetres.

The national weather agency said around 10 millimetres of rain already fell overnight, and that the rain will be heavy at times.

680 NEWS meteorologist Jill Taylor said 40 km/h winds are also expected.

The rain is expected to taper off later this evening; however,Taylor said there is also a chance of showers on Friday.

So far this month, Pearson Airport has already received 82.6 millimetres of rain. The average for this month is 74.3 millimetres.

“We’ve only had a four-day stretch without measurable rainfall (May 8-11), so on and off rain-showers for a good chunk of month,” Taylor said.

The heavy rain could also threaten the already high water levels at the Toronto Islands.

More than half of the buildings on the islands are being threatened by rising water levels, Mayor John Tory said earlier this week. About 40 per cent of the Toronto Island Park is already under water.

Unusually high water levels in Lake Ontario brought on in part by heavy rains in recent weeks have largely shuttered parts of the islands, which boast beaches, an amusement park and other tourist attractions.

The city said permits for events on the island have been cancelled until June 30, and ferry service is restricted to residents and staff only.

Taylor said it looks like the GTA will have a dry stretch to start June but that temperatures will remain below average.
