I understand that an endeavor such as this is driven by a desire to provide something useful for others. As one individual I can confirm that achievement. I am a retired boat captain, living on a sail boat currently in N. Carolina, U.S. I use the wind overly and wave height and direction overlay, and now the radar display on literally a daily basis. It is part of my morning routine; pour a cup of coffee, delete my spam mail, study the wind patterns. As your 2017 comment stated, last year during the storms that hammered the U.S. east and Gulf coasts I studied these overlays on nearly an hourly schedule to make decisions on what to do with my boat (my home) in preparation. Of all the available resources, Windy is by far the most useful in determining what may happen tomorrow with these storms. As a form of "insurance" towards the safety of my boat (my home) I would pay a monthly subscription for this service.

RE: About Windy
RE: Local areas where wind direction meets
I'm not a meteorologist, but as I understand it, "wind" is just air moving from a high pressure area into a low pressure area in an attempt to equalize the two. The greater the difference in pressure and the closer the two areas are to each other the faster the air moves. It's not so much that the air moving in different directions cancel each other, rather, when the moving air reaches the center of the low pressure area it loses the pressure differential to push it. The dark blue areas on Windy can be either low pressure centers with wind moving towards it, or high pressure centers with wind moving away from it. The drastic form of this is when a low pressure forms within a high pressure, completely surrounded. This is when the air begins to rotate in towards the center. As the air picks up speed, fueled by heat which thins the air causing it to rise and lower the pressure even more, the low pressure center becomes even lower. Depending on the amount of heat put into this "engine" it can develop into a cyclone or hurricane. Never-the-less, the center of a cyclone is usually a dead calm.
RE: Help us to test new Weather Radar overlay
This is the most useful tool to be able to evaluate what's headed your way in the next few hours. The only thing that would make it even more useful would be to blend it with satellite cloud imagery as well - not as easy as 1,2,3, but a further challenge for the windy programmers!
