On the weekend very heavy rain fell in many parts of Ontario and Quebec. Over 37mm fell in Kemptville, that was over half our May total in one day. About twice that fell south of Montreal in Huntingdon. The result was flash flooding of many basements, the second time this has occurred in less than a year. The Quebec government had promised to replace the aging sewer system in the Village, but has yet to do so.

A tornado occurred in southern Manitoba over the weekend near Niverville, close to the North Dakota border (see above). The storm was on the ground for about 8 minutes and produced only minor damage, and no injuries.

Hurricane season in the Atlantic basin began June 1, and right on schedule was the first storm of the season, Arthur. The weak system slid across the Yucatan peninsula and into the Bay of Campeche before dissipating to a depression.
