Warnings Posted

Low pressure is pushing a wide area of precipitation across New England, Ontario and into Quebec at this hour. Winds are increasing from the northeast, and cooler air is being drawn down the St. Lawrence Valley. Expect rain to begin shortly across the city and mix with freezing rain or wet snow overnight and Tuesday. The heaviest rain will fall in New England where 50 to 100mm (2-4 inches) is possible. Flood watches have been posted for Vermont and New York. Across our regions heavy rain is forecast in the Townships where warnings have been issued for up to 50mm. Meanwhile the colder air in place over the Laurentians and Ottawa Valley will result in pockets of freezing rain. All precipitation will end as a period of wet snow late Tuesday with 1-3cm possible. Freezing rain warnings are in effect for all of Eastern Ontario north of the St. Lawrence Valley and for the Ottawa Valley. They have also been posted for the Laurentians. Meanwhile heavy wet snow is forecast from Quebec City north and east with upwards of 15-20cm expected. Winds will be gusty out of the northeast to 60km/h. Travel will become very poor on area highways tonight and continue tomorrow, especially northeast on highway 20 towards Quebec City, north on the 15 into the Laurentians and northwest on the 40 towards the 417 and Ottawa.
