Water your trees, city urges homeowners - The Globe and Mail:
Toronto residents are being urged to water vulnerable trees after the longest string of rainless days in 47 years.
A trace amount of rain — less than 0.2 millimetres — fell on Toronto on Friday morning after 18 straight days without any precipitation. The city has had only three longer unbroken dry spells since records have been kept at Pearson Airport: A 26-day spell in 1938, followed by two 21-day droughts in 1957 and 1963.
“This is a milestone of sorts,” said Environment Canada senior climatologist David Phillips, noting how much has changed from the cold, cloudy months of June, July and August that made this summer the fifth wettest on record.
“It was like the faucet was on and then it was turned off.”
