Not so! Maybe wait a few seconds.
There is a strong wind blowing into central Africa from Egypt, north east over Tibet, north into central Australia fron the Great Bight, and as for Antarctica! It may, of course, have changed if you're not looking at this again for some hours. And the land tends to weaken sea bourne winds, just because it, well, gets in the way.
This, like the interactive view of Comet 67P, and maybe more so, is an masterclass in integration of data. You can look back in time and forwards in forecast, as well as add all those other parameters (I like the Misery Index!)
I can see the remnant of Hurricane Matthew heading for the UK, but thanks to the unusual, for this season, high pressure over Scandinavia, halting in the Western Approaches, weakening and moving southwestwards towards Spain where it will probably be no worse than an ordinary depression. But in the same time frame, another intense depression forms over Bermuda and moves north east parallel to the North American coastline,intensifying all the time until it's off Newfoundland and we reach the limit of the forecast, about two days from now.
On both sides of the North Atlantic, we're in for a bumpy ride this Autumn!
