The map above is a screen grab from an animated wind map. If you go to the site hint.fm/wind, you will see that the lines move in the direction of the wind, and the speed of the moving lines varies depending on the actual wind speed. The data is downloaded from the National Weather Service’s database every hour, so what you will see there is near real-time conditions.
It’s interesting that on the site, they advise that you: “Please do not use the map or its data to fly a plane, sail a boat, or fight wildfires “.
Check it out. It’s mesmerizing.
(Note: when you go to the site, it takes a lot of computer horsepower to animate the map . It may not work on your smart phone, or even on your computer. They advise: “If the map is missing or seems slow, we recommend the latest Chrome browser.”)
