Weather Situation
Mostly settled conditions will continue across coastal waters until a small low pressure system and associated trough moves over coastal waters through Tuesday. This trough will push inland through Wednesday resulting in a south to southwesterly airstream across coastal waters. A high pressure ridge will begin to extend over western waters late Wednesday with the high pressure centre establishing in the Bight by late Thursday.
