5 DAY ICE DISCUSSION...

THE ONLY ICE OF SIGNIFICANCE THAT MAY AFFECT SHIPPING IS ALONG THE ST
MARY`S RIVER AND NEARBY AREAS. NEAR NORMAL TO ABOVE NORMAL
TEMPERATURES THROUGH EARLY NEXT WEEK WILL ALLOW SLOW TO MODERATE ICE
MELT TO OCCUR WHICH SHOULD ELIMINATE MUCH OF THE REMAINING ICE
COVER. THE COMBINATION OF WINDS 25 KNOTS OR LESS AND THE FACT THAT
THE ICE IS IN PROTECTED AREAS SHOULD LEAD TO THE WINDS HAVING LITTLE
OR NO EFFECT ON THE ICE FIELDS.
