Changes to Bass Strait and Victorian Coastal Waters forecasts

A number of changes to the Bureau's Bass Strait and Victorian Coastal Waters forecast services are scheduled to occur from Wednesday 2 November 2005.

Forecasts will be issued in the early morning and late afternoon. Updates will be issued at other times if the weather pattern changes markedly from that described in the current forecast. In addition, and to provide a better service for mariners, sea and swell information will be included on the third and fourth days of the forecast.

The forecast areas around Australia have undergone some changes to better represent the 60 nautical mile coastal boundary (see map following). The individual zone names will also change to better describe the coastal areas.

To avoid overlap, the current "Southern Bass Strait" forecast zone will no longer form part of the Victorian coastal waters service (see Table 1). Forecasts for these waters will be divided into three coastal zones across northern Tasmania. These three zones will be included in the new "Bass Strait and approaches forecast" (shown with the symbol * in Table 2). The "Coastal Waters Forecasts for Tasmania" remain unchanged.
