"NavTools StormTrack allows you to track tropical storms (including hurricanes, typhoo"
By SoftCns Editor:

NavTools StormTrack allows you to track tropical storms (including hurricanes, typhoons, cyclones, etc.) all over the world and view their forecast track as well as the closest point of approach to your present location or intended route. Although created for merchant navy vessels, the software will be very handy as well for yachts or other vessels or even stationary targets (your home, office, etc.).

In above example is situation is shown with one tropical storm and an intended voyage from Canada to Europe. Present position of the tropical storm is shown in red with radius of the circle showing the radius of the storm (maximum wind). Forecast positions of the storm and their respective radius are shown in orange (as can be seen the storm is expected to increase in strength). Our intended sailingroute is shown and crosses the forecast track of the tropical storm, however the color of the track (green) already shows we will pass clear of the stormfield. Should any position on the route pass within the stormfield, the route will show up in red.
