Fig8.1.16.1-4: Sample wavegram (at the point indicated by the arrow in Fig8.1.16.1-3) for the same time as shown in Fig8.1.16.1-3.  Note waves early on 10 January are forecast to move towards the westsouthwest with a small probability of significant wave height exceeding 10m. When referring to such products one must understand innate difficulties of correctly representing the winds around tropical cyclones, and this will also impact upon the representation of waves nearby.
