Nor'easter may not bring the snow, but watch out for the wind

Bright sun and cold air greeted us Tuesday afternoon in Moncton, NB, not at all a harbinger of what is about take place in the form of a Nor'easter.

From the airport, it took about an hour to reach the Confederation Bridge to Prince Edward Island. Opened in 1997 it's a 12.9 kilometre long, 11 metre wide ribbon on concrete that sits 40 to 60 metres above the Northumberland Strait. It will bear this storm well, but there are rules.

The bridge has only been totally closed to traffic a half dozen or so times in the past 15 years. Restrictions to high-sided vehicles are imposed when wind speeds reach 70 km/h (no transports allowed when it's that gusty) and the bridge is closed to traffic when winds reach 115 km/h.

Early indications point to Wind easily surpassing that threshold with this storm.

Above 115 km/h? Those winds are hurricane force. This storm will carry snow, too. In the range of 20, 30, 40, and maybe 50 centimetres.

If you recall, the infamous accumulations of White Juan 10 years ago offered Charlottetown 75 cm of snow with winds peaking at 96 km/h.

This storm may not offer as much snow, but instead, the wind will be the enemy. And with the wind, there comes the waves and the moving sea ice.

Wind storms such as this historically produce some measure of coastal flooding and erosion. Maximum energy from this storm might well coincide with high tide, which is not something to underestimate.

Be safe. Our teams have fanned out across Atlantic Canada to show you the power of nature and to keep you informed and aware of any danger.
