More thunderstorm watches west of Ottawa-Gatineau

Environment Canada has again issued severe thunderstorm watches for parts of eastern Ontario and western Quebec for Wednesday afternoon and evening, with the possibility of hail, strong winds and a tornado.

The watches cover communities west and north of Ottawa-Gatineau including Bancroft, Maniwaki, Pembroke and Shawville, and follow strong storms that swept through the region late Tuesday afternoon.

All watches as of 11:15 a.m. mention wind gusts of up to 100 km/h, as well as hail.

Most mention the risk of a tornado, but that’s not in the alerts for the area north of Gatineau.

These parts of western Quebec could also get about 40 millimetres of rain.

Ottawa’s main airport recorded 17.4 millimetres of rain in a few hours during Tuesday’s storm, the greatest single-day volume in six weeks.

Wednesday’s forecasted high temperature in Ottawa is 30 C, with humidity making it feel as hot as 37. The capital hasn’t reached 30 C since early October.

Daily heat records are possible Wednesday in communities including Brockville, Cornwall, Kingston and Belleville.
