Live turbulence and storm maps
The same information pilots look at before and during a flight, drawn in the style of the US Aviation Weather Center maps and updated every few minutes.
Turbulence and storm warnings (SIGMET and AIRMET)
Official warnings for pilots. Each shaded area carries a label: Turb means turbulence, TS thunderstorms, Conv convective weather (storm clouds), LLWS wind shear near the ground and Ice icing. Brown areas are turbulence warnings; orange areas are forecasts for the coming hours over the United States (G-AIRMET). Airlines plan their routes around these areas.
Pilot reports (PIREP)
What pilots actually felt in the air over the last two hours. A caret ^ is light turbulence, a double symbol is moderate and a filled one is severe; the number under it is the flight level (FL350 ≈ 35,000 ft). Blue means no turbulence, green light, orange moderate and dark red severe. Most reports come from the United States, where pilots send them most often.
Airports right now (METAR)
The current weather at each airport. The circle colour shows flying conditions: green good, blue fair, red poor and purple very poor (low cloud or fog). How full the circle is shows how much of the sky is covered by cloud, and the line shows where the wind comes from.
Airport forecasts (TAF)
What forecasters expect at each airport over the next 24 to 30 hours. Same colours as the METAR map. On the full-screen map you can move the time bar forward hour by hour.
