10 Weather Forecast

  10.1 Where possible a weather forecasting source should be available on a 24-hour basis for the whole towing operation.

  10.2 Weather forecasts should, as a minimum, contain the following information:

  • Synopsis of the area
  • Wind speed and direction
  • Wave height and period
  • Swell height and period
  • Outlook for the next 48 hours.

  10.3 In certain high risk situations, or when such forecast may be seasonally unpredictable, consideration should be given to obtaining a second weather forecast.

  10.4 Weather forecasts should be received on the towing vessel (and received or relayed on the towed object if manned) at least every 24 hours during the towage. Where there are specific weather limitations imposed, then more frequent forecasts may be appropriate, and possible direct communication with the forecaster if significant changes are expected.
