Synopsis

Technical Marine Synopsis

Issued 10:00 AM AST 18 February 2018 Today Tonight and Monday At 10:00 a.m. AST today intensifying low 995 mb located over

By 8:00 p.m. AST tonight departing low 984 mb located south of

Marine Weather Statement

Issued 11:26 AM AST 18 February 2018 An intensifying low pressure system currently over Georges Bank will
rapidly cross southern waters today to lie south of Laurentian Fan
this evening. Gale to storm force winds will continue to spread to
waters south of Nova Scotia today, with a brief period of hurricane
force winds near the track of the low centre over Georges Bank to
East Scotian Slope. Winds will diminish from west to east as the low
passes by and a ridge of high pressure builds into the region.

Recent observations over Extreme Southern Georges Bank have indicated
that wind speeds associated with the passage of the low centre may be
capable of reaching 75 knots. As a result, the Georges Bank and West
Scotian Slope forecasts have been updated.

In addition, high storm force winds are in effect for Laurentian Fan
associated with the passage of this rapidly developing low pressure
system. There remains some uncertainty with how quickly this low will
intensify as it begins to exit the marine district. It is possible
that the strongest winds over Laurentian Fan may reach hurricane
force this evening; however, at this time storm force winds up to 60
knots are expected.

Marine interests are advised that hurricane force wind warnings are
in effect for Georges Bank, West Scotian Slope and East Scotian
Slope. A storm warning is in effect for Laurentian Fan. Gale warnings
are in effect for Browns Bank, lahave, Sable, and Banquereau-southern
half.

Marine interests are also advised that freezing spray warnings are in
effect for all Gulf of St. Lawrence waters.
