Wind Warning Changes

Introduction

Marine wind warnings to be issued for 'today' and 'tomorrow'.

Mariners in Queensland, Victoria, New South Wales, Western Australia, Tasmania and South Australia will be able to see when wind warnings are current for up to 42 hours ahead. They'll also be able to get statewide overviews of the warnings. The wind warnings will say which day is affected, and will be included within the Coastal Waters forecasts. The forecasts will be updated every 6 hours whenever a warning is current.

By including the wind warnings in the forecasts, there will no longer be a need to issue separate wind warnings. However, a new statewide summary will show all the Coastal Waters and Local Waters affected by warnings for that day and the following day.

When will the new service begin?

The Bureau of Meteorology will introduce the changes for Queensland in October 2013 and Northern Territory in 2014. Victoria and New South Wales were completed in 2013, Western Australia in 2012, and Tasmania and South Australia in 2011.

FAQs for new wind warning service

What's new?

  • Marine wind warnings will cover the first two days - not rolling 24 hour periods.
  • A wind warning label will be added to the Coastal Waters Forecast for days one and two indicating the highest category of wind warning applicable.
  • The Coastal Waters Forecast will usually be issued every 6 hours during wind warning periods.
  • The lead time of the warning statements will increase by 24 hours – i.e. giving up to two days advance notice in some instances.
  • A Marine Wind Warning Summary will be issued during warning periods, covering all the State’s coastal and local waters. It will make it easy to see all zones affected by wind warnings for days one and two.

Why change?

Feedback indicated confusion as to the period for which the warnings applied. Mariners have commented that the Coastal Wind Warning was divided into too many sub-sections, making it difficult to broadcast and understand via marine radio. Marine radio broadcasters highlighted that:

  1. the warning information was becoming too lengthy to read out within the allocated schedules and interfered with distress monitoring duties; and
  2. detailed information about changes in wind speed and direction during days one and two of the forecast period was available in the coastal waters forecasts resulting in duplication of information being read out during broadcasts
