Weather Map Layers

Summary: Switching on live weather overlays such as rain radar, cloud cover and wind, and the significant-weather and pilot-report layers.

The map includes a set of live weather overlay layers, powered by OpenWeatherMap, that you can switch on independently or combine: Rain Radar, Lightning, Clouds, Temperature, Wind and Pressure. These sit on top of the base map alongside any other layers you have active, so you can, for example, check rain radar against a flight you’re tracking or an airfield you’re watching.

SIGMETs and pilot reports

SIGMETs draws current significant-weather warnings as coloured areas: red for storms, orange for turbulence, blue for icing, purple for mountain wave. Click one for the hazard, whether it was observed or forecast, the area with its corners, the levels, the movement, the trend and who issued it, all in plain English with the raw message under a fold.

Pilot reports shows reports from aircraft that met turbulence or icing as dots. Routine reports, the wind and temperature reports airliners send at cruise, are a separate chip because there are hundreds at any time; it is off unless you want them.
