From Tuesday 28 October 2008 a number of marine service enhancements will be introduced in Victoria to improve the usability of marine forecasts and provide mariners with an improved level of service.
As of 28 October 2008, Victoria will have four coastal waters zones instead of three. The current East coast zone which covers Wilson's Promontory to Gabo Island will be split into two zones at Lakes Entrance. The new boundary will be located between Lakes Entrance and Flinders Island forming two coastal zones named Central Gippsland Coast and East Gippsland Coast.
This new division will provide mariners with more detailed coastal waters forecast information between Wilson's Promontory and Gabo Island.
Forecasts for Port Phillip and Western Port are currently issued as a combined
text-based product. This also applies to the warnings for these two areas.
As of 28 October 2008, Port Phillip and Western Port local waters forecasts
and warnings will be available as separate products. Separating Port Phillip
and Western Port will provide a more detailed level of forecast information
for these two adjacent local waters areas.
Also, terminology for wave information in these forecasts will be consistent with the coastal waters forecasts. Therefore sea (or wind) waves will be referred as 'Seas' in the forecasts.
Coastal and local waters marine warnings have been improved to highlight the
worst conditions expected within the next 24 hours. Warnings will focus on
the highest winds and highest waves expected in a designated area. Note
that these highest winds are averages and do not include gusts. Similarly the
highest waves are the significant waves and not maximum waves. For more information
on wind and waves see: About
Mariners are reminded that more detailed information is contained within the coastal and local waters forecasts.
The highest waves are derived from the expected total wave height and consistent with terminology used in coastal waters forecasts, the highest waves will be referred as 'Combined sea and swell'.
Note that the wind warning thresholds for strong winds, gale, storm force and hurricane force wind warnings remain unchanged.
