Re: Irma, Jose and Katie . .


Oh wow, it's quite lovely!  I've been using the Ventusky site, which is nice because you can click to choose weather features such as wind speed, precipitation, temperature, and so on.  Viewing the wind speed and wave height maps at the world scale puts me in awe of sailors in any era venturing into the Roaring Forties!

However, the Ventusky map is flat, and I really like the way the EarthWindMap is shown on a globe.  Both sites are mesmerizing!

Thanks for the link, Chrístő.  I'm in Florida (northern part), and we're all watching the approaching hurricane.
