Marine Weather Statement

Issued 2:56 AM NST 10 December 2018 An intense low pressure system well northeast of Funk Island Bank
will continue to drift away today. Gale force northwesterlies over

be expected over all waters as the trough passes.

but that could change with even a slight shift northward in the
