Storm totals

The intense low pressure area that moved from Boston into Maine yesterday, produced a major storm across the entire region. Snowfall amounts of 7cm were recorded at Dorval, a record for the date. The total precipitation was 36mm at the airport and 38mm at my place, that is nearly 1.5 inches of water equivalent. The snow depth varied on the island with over 10cm in the central part of the city near the mountain with lesser amounts off island on Ile Perrot. South of the city was a different story. Snow accumulated 10 to as much as 30cm near Granby and St Jean. The snow produced 2 fatal accidents on area roads as well as downed trees and power lines. Power is out this morning to nearly 35,000 Hydro Quebec customers with nearly the same amount out south of the border in Vermont and New York. Warnings remain in effect from the Townships into Vermont and New York with storm totals of 20 to 40cm expected.

For the record, the latest storm in Montreal was 21.8cm on May 10, 1963 with the latest measurable snow May 17, 1959 when 1.8cm was observed.

Skies should clear later today with the mercury reaching 11C and melting the snow here in the city. It may take a day or so elsewhere. Drive with care today especially south and east of the city.
