Severity: Moderate Urgency: Future

Locally fresh and strong NE wind. Maximum wind gusts 35-40 knots (65-75 km/h)

IMPACT: Although rather usual in this region, locally or potentially dangerous wind speeds are expected to produce dangerous wave conditions to small crafts. Inexperienced mariners, especially those operating smaller vessels, should avoid navigating in these conditions. Mariners should pay close attention to the marine forecast and consider wind and sea conditions in planning. It is possible that some ferry lines will not operate so follow traffic information if travelling.

Event: Yellow wind warning Certainty: Possible Category: Met
