  I am struggling to find a solution for this as well. I was hoping a simple URL parameter would do the trick, but I haven't found one yet. I've tried the same ones you have, as well as things like "playPause", "animation", "play", "loop", "start", etc. And I've tried values of "1", "on", "true" for all of those. I guess it's just not supported. I did see somewhere else that someone was able to send a javascript command to click the "playpause" button after loading. But I'm using iframe within my Home Assistant server and don't have the ability to pass javascript. :(

  One of the typical feature of a medicane is the hot core which is much warmer than outside. It is very interesting and instructive to follow it at different levels. At the beginning, you could notice the difference at low levels, 850 hPa for instance but day after day, you can see the differences, in the core and outside, also at much higher levels. This is because in the development process of an hurricane, the system releases latent heat, among others because of the condensation of warm and humid air at higher and higher level. Here you can see it clearly on the follwing map at 600hPa : +2°C in the core, -2 or -3°C outside. Huge difference ! Very instructive to follow the development of this medicane

  @Jenny21 As explained, the default setting, map and model, cannot be changed and there is a reason for that : at this stage of the development of the application, giving the possibility to the user to change de default setting would lead to some technical issues and will considerably slowdown the application. Explanation is here : https://community.windy.com/topic/9422/how-to-change-default-start-up-layer-on-windy

  Hi Petra, One other thing I forgot to mention, is that the major fire that is 12 miles away from me, has been roaring for 8 days, so isn't in the category of "sudden events like fires". Forecast information is only valuable if the accuracy is validated by looking at it when the forecast date arrives. If the forecast is close then it is valuable, but if it is way off then it isn't. In fact it can actually be harmful. I am hoping that Windy.com wants to be recognized as a quality site and grow because of accuracy measured over time. Garbage in garbage out applies to the PM2.5 data.

  Hello @alan345_33, the PM2.5 layer is a forecast, not a real-time reflection of what is happening. Air quality stations are reporting current values. If there was a sudden event, the forecast is not able to reflect it.

  @Ms-Klein In the quick menu, right side of your screen, select More layers...Then scroll down and tick Geopotential heights which the heigh at a given pressure. When selected together with Wind at 250 or 300hPa, you get the picture of Jet stream as predicted by the model along the isohypses.

  Hello @lhessel, short term forecast models feature narrow forecast time and are thus vulnerable in their sensitivity to soaring variations in air quality, defined as sudden events. It can happen that the forecast doesn't correspond with the real-time situation. In which area are you noticing this?

  @Gkikas-LGPZ Thank you for information. It was fun to imagine what the clouds were like and what was like when it happened.
