When I load the embed source outside the <iframe>, I'm tapped by Safari to allow windy.com access to location data. This, at least theoretically, shouldn't be necessary since the requested lat/long is within the embedded URI and browser location may be meaningless to the request (the browser may not be located at the requested location). Is there an API flag to suppress the request for the browser's location?

Great example, and very close to what we are trying to do. We're trying to find a way to embed the animations used by windy.com but with our own weather models in the backend ... also leveraging the Javascript for ArcGIS platform to make widgets/panels interact with each other. Can the following be done: using the Javascript for ArcGIS as the primary platform, but including some visualisations from windy.tv ; and/or connecting the windy.tv front end to our own back end weather data?
