Marine Weather Statement

Issued 2:59 AM AST 18 January 2018 A low pressure system currently over eastern shore will continue to
track northeastward today to lie over Central Newfoundland by this
afternoon. Strong southeasterlies ahead of this system over eastern
waters will switch to northerly in its wake.

A second low pressure system has formed southeast of Cape Hatteras
and will track towards the marine district to lie south of East
Scotian Slope by early Friday morning. Strong to gale force
northeasterlies ahead of this system will develop over southwestern
waters this evening and spread northeastward across southern waters
throughout Friday.

There remains some uncertainty on how close this low pressure system
will track near the southernmost waters. Should this low pressure
system track further northward than is currently expected, stronger
gales or storm force northeasterlies may develop over Georges Bank
and West Scotian Slope later this evening and overnight. Environment
and climate change Canada will continue to monitor the situation and
issue updates as new information becomes available.

Marine interests are advised that a gale warning is in effect for
Georges Bank, West Scotian Slope, East Scotian Slope, and Laurentian
Fan.

Marine interests are also advised that freezing spray warnings are in
effect for Gulf-Magdalen and Anticosti.
