Issued 2:46 AM ADT 17 August 2017 A low pressure system north of Anticosti Island will move
southeastward across the Northeastern Gulf of St. Lawrence to lie
over Eastern Newfoundland this evening. Strong to gale force westerly
winds will develop over much of the district today as the low passes
by to the east.

Marine interests are advised that gale warnings are in effect for
eastern shore, Fourchu, and Banquereau-northern half.

Marine interests are also advised that the combination of cool air,
warm waters and favourable atmospheric conditions will give the
potential for waterspout development on Thursday over the Gulf of St
Lawrence waters.

and 55.6 degrees west, or 380 nautical miles south-southwest of Cape
