What can change a route in the Mediterranean during the warm season? Often not the general weather, but rapid phenomena, colds and reduction of visibility. This is why the control should be carried out on the single route and not in a generic way.
First question: where is the notice?
Coordinates, date, time and categories of units determine the application of the arrangement. The problem to prevent is to wait for rain to reduce canvas or look for shelter when the front is already close.
Second question: What should I do?
The operational response is to establish preventive thresholds and prepare crews, blankets and equipment before worsening. If you can't bring it back to the navigation plan, reading is not yet complete.
Third question: where can I deviate?
It is sensible to stay in port or anticipate return when uncertainty exceeds the operating margin. Also check publications of the Hydrographic Institute, Orders of the Coast Guard and communications of the competent local authority. Effective prudence arrives before the emergency: change program in advance keeps options, autonomy and clarity.
