Synopsis
Coastal low pres will move into the Maritimes today. This will generate a W flow across the waters through mid-week. Developing low pres will emerge off the coast late in the week, potentially developing into a gale center which may pass in the vicinity of the 40N/70W benchmark sometime Fri into Sat.
