This paper describes a number of occasions on which German ships have successfully avoided tropical revolving storms by using information which is at the disposal of the mariner today. Similar accounts could obviously be given of storm-avoidance by the vessels of other countries, but it is thought that this compilation, by a member of the German Weather Service, will interest many seamen. The paper was presented at a meeting of the Ausschuss für Funkortung held at Kiel on 10, 11, 12 September 1960, and is published with the kind permission of that body.
