Marine Weather Statement

Issued 9:56 AM NDT 17 August 2017 A low pressure system will strengthen off the Northeast Coast of
Newfoundland tonight then slowly pull away to the east on Friday.
Strong to gale force winds can be expected around this low overnight
and Friday.

At 9:30 A.M. NDT hurricane Gert is forecast to be near latitude 42.3
north and longitude 51.7 west, or about 268 nautical miles
south-southeast of Cape Race. Gert is moving east-northeastward at
about 41 knots with a central pressure of 972 MB and maximum
sustained winds of near 80 knots.

Gert is forecast to track just along the southern boundary of the
Southern Grand Banks today as a hurricane but the associated
hurricane force winds should stay south of the Grand Banks. A brief
period of gale to storm force northeasterlies is forecast to spread
over the southernmost waters ahead of Gert, then shift to strong to
gale force northwesterlies in its wake. Gert also has the potential
to bring high swells to southeastern coastal Newfoundland.

Hurricane Gert may also cause a series of rapid changes in water
levels in harbours and inlets around the Avalon Peninsula, especially
from the southeastern tip of the Avalon Peninsula North to Trinity
bay. This is most likely to occur for a couple of hours later this
afternoon into this evening. As high tide will be occurring late this
afternoon for most areas, there is a risk for minor coastal flooding
during this time.

Marine interests are advised that a storm warning is in effect for
the Southeastern Grand Banks - southern half. Gale warnings are in
effect for the South Coast, East Coast, Northeast Coast, Funk Island
Bank - northern half, Southwestern Grand Banks and Southeastern Grand
Banks - northern half.
