On Tuesday, experts at Environment Canada reported that 60 to 170 millimeters of rain were expected in southwestern Newfoundland with winds between 60 and 110 km/h.

David Phillips, senior climatologist, says that November is the wettest month for both coasts, so it should come as no shock that these regions are receiving incessant rains. However, he says it is important to take into account the potential for rain that has accumulated over such a short period of time, especially within British Columbia.


“Sadly, we’re in the wet season on the West Coast… Normally when November ends, you only have 40 percent of the wet season. You still have December, January, February and March ,” said Phillips.

How much rain is expected on both coasts?

Up until this point, Phillips says, Chanel-Port aux Basques, NL, saw 68 millimeters of rain on Tuesday. Today meteorologists were calling for 60 to 80 mm of rain in flat land near the coast, but 120 mm of rain is expected in more remote areas. As of tomorrow, Phillips says southwestern Newfoundland will have reached a storm total of more than 200 millimeters.

As for the west coast, Phillips says there’s going to be a parade of atmospheric rivers in BC’s south coast. Although these rivers won’t last as long as they were a few weeks ago, some areas that were hit by flooding will be like this. It is already a vulnerable state as it is more affected by the storm.

“Today’s 60 millimeters of rain is more impressive than the 60 millimeters of rain three weeks ago, when the ground is already saturated,” Phillips said.

100 to 150 mm of rain is expected over Vancouver Island and winds will be in the range of 90 to 110 km/h.

What is atmospheric river?

According to Phillips, an atmospheric river, also known as a Pineapple Express storm, is a large stream of water vapor. Atmospheric rivers usually come from the subtropics, where there is warm water in places such as the Caribbean, and in this case, Atlantic Canada.

These waters are full of moisture, says Phillips, and when large amounts of moisture hit coasts, land, and mountains, it can result in days, weeks, or even months of rain.

How long will the storm last?

In Atlantic Canada, Phillips says the rain began Monday night and lasted through Tuesday night, hitting Cape Breton Island, N.S.

For Channel-Port aux Basques, Environment Canada says 110 km/h southeasterly winds will prevail overnight that will ease by Thursday morning.

Has one storm caused another?

“There is nothing in British Columbia that is affecting Newfoundland, and there is nothing in Newfoundland and Labrador that is affecting British Columbia, all of which have their own misery out the window,” Phillips said.

What security measures can we take?

Environment Canada advises that if visibility decreases while driving, slow down, look at the taillights ahead and be prepared to stop. Rapidly flowing water on the road can cause the vehicle to drift away, so leave it if the car is stalled and the water is rising rapidly.

Do not go near washouts near rivers, creeks and culverts. People in low-lying areas or valleys should be prepared to move to higher areas before fast-rising waters. And be prepared if you need to vacate your residence for a longer period.
