Hydro One’s website reported at least 30,000 outages at one point on Saturday. This is an unusually high number of outages given that winds have remained generally 70 km/h or less.

Some of the strongest gusts reported included 72 km/h at the Muskoka airport and a 69 km/h gust in Sault Ste. Marie. Gusts were generally between 60-70 km/h throughout the Greater Toronto Area.

Winds lessened greatly into Sunday as we lost the tight, air pressure gradient responsible for the blustery conditions.

Another quick-moving, rainy system is possible in southern Ontario late Sunday evening into Monday morning, though with higher uncertainty. Communities across southwestern Ontario could see isolated, non-severe thunderstorms embedded within the larger system.

Comfortable temperatures and drier conditions will arrive for the final days of May.
