Timing: Until Wednesday.

Synopsis: Fresh winds, due to a tightening pressure gradient, is forecast to cause a combination of wind waves and wind swells to rise, resulting in hazardous seas. The threat level to the life, livelihood, property and infrastructure of mariners is significant, and there is the potential for extensive impacts. A small craft advisory means that wind speeds of 21 to 33 knots and or wind waves and or wind swells of 7 feet or greater are occurring or imminent.

Winds over open waters: East-northeast at 26 to 37 km/h (14 to 20 knots; 16 to 23 mph), with strong gusts to gale-force or around 57 km/h (31 knots; 36 mph).

Seas (significant wave heights): 2 to 2.8 metres (6 to 9 feet), occasionally or locally reaching over 3.5 metres (near 12 feet). Wind waves and or wind swells: 1.5 to 2.5 metres or 6 to 8 feet and occasionally higher. Dominant wind wave period is 6 to 9 seconds.

Potential Impacts: Loss of life at sea; injuries to mariners; damage or loss of boats and marine equipment; financial losses; disruption of fisheries and scarcity of fish products and disruption to marine transportation.

Caution: Inexperienced mariners, especially those operating smaller vessels should avoid navigating in these conditions.
