Maximum sustained winds are near 75 mph (120 km/h) with higher gusts. These winds are occurring mainly over water. The post- tropical cyclone is forecast to drop below hurricane strength after passing Newfoundland later today, and it is forecast to be absorbed by another large low pressure system in a couple of days.
