EUMETSAT's Metop-B image shows Matthew as a category-5 hurricane, just before the centre of the storm made landfall over Haiti. The enhanced colour image, Figure 1 shows the extent of the coldest cloud tops (red) which indicate the most active areas of the storm.
The winds from the ASCAT scatterometer (Figure 2), onboard Metop-B, also clearly show the storm's centre — the region of hurricane force winds (the bright red wind markers around the distinct eye).
As British weatherman Tomasz Schafernaker pointed out on Twitter, the region of hurricane force winds is very small, compared to the size of the actual hurricane – very much confined near to the storm centre, surrounded by a much larger area of storm force winds.
Figure 3 shows the hurricane after it had passed over Haiti. This is the visible channel from Metop-B, with the ASCAT winds overlaid. Three days later, on 7 October, the hurricane passed between Florida and the Bahamas as can be seen in Figure 4 with the Metop-A IR10.8 channel, in false colours.
