West Davis

Issued 3:26 PM EST 19 November 2018 Strong northerly winds of 40 to 55 knots have developed today and will persist into Tuesday as a strong low pressure system tracks westward from the Atlantic Ocean into Davis Strait. The strongest storm force winds will occur off the tip of the Cumberland Peninsula, with wind gusts up to 70 knots possible. Some snow is expected to spread across the region and combined with the strong winds, blizzard conditions with near zero visibility can be expected tonight through Tuesday particularly near the ice edge.

Marine interests in the area should also be aware of the possibility of rapid development of an intense, compact low pressure center in the southern Brevoort region this evening and tracking northwards. Sharp changes in wind speed and direction will occur in the vicinity of this developing low.
