Technical Marine Synopsis

Issued 10:00 AM ADT 10 April 2020 Today Tonight and Saturday At 10:00 a.m. ADT today low 965 mb located over the Bay of Fundy.
By 8:00 p.m. ADT tonight low 974 mb located over the Gulf of
St. Lawrence.

At 3:30 p.m. ADT Saturday low 984 mb located over Labrador.

Marine Weather Statement

Issued 9:40 AM ADT 10 April 2020 An intense low pressure system will track through the Bay of Fundy to
lie over the Gulf of St. Lawrence this evening. The low will track
slowly northeastward on Saturday. Gale to storm force easterly winds
ahead of the disturbance will become strong to gale force westerlies
in its wake.

In addition, due to a series of abnormally high astronomical tides,
this system will bring higher than normal water levels and a
likelihood of coastal flooding to Miramichi northward to the Acadian
Peninsula and the Bay of Chaleur and along the coasts of iles de la
Madeleine late this morning. This will also occur for the Yarmouth
area at high tide around noon. Higher than normal water levels and
rough surf is expected along the Atlantic Coast at high tide this
morning. There may also be some minor flooding along parts of the
Northumberland Strait coast of Prince Edward Island near noon.
Finally, there may be some coastal erosion and damage due to rough
and pounding surf along east facing shorelines in the Gulf of St.
Lawrence, especially for Northern New Brunswick, Gaspésie and iles de
la Madeleine.

Marine interest are advised that high water level warnings are in
effect for Lurcher, Chaleur-Miscou and Gulf-Magdalen.

Marine interests are also advised that storm warnings are in effect
for Cabot Strait, Gulf-Magdalen, Chaleur-Miscou and Anticosti -
southeastern half. Gale warnings are in effect for all remaining
