US SIGMETs and AIRMETs Currently in Force (Aviation Weather Center)

aviationweather/airsigmets

The domestic (United States) SIGMETs and AIRMETs valid right now: for each advisory its type, hazard (convective, turbulence, icing or IFR), series and issuing office, valid-from and valid-to times, altitude range in feet, movement direction and speed, the raw advisory text and the polygon of the affected area as latitude and longitude points. Choose the hazard (conv, turb, ice or ifr), and optionally the product type (sigmet or airmet) and an altitude in feet to search within 3,000 feet of. No advisory in force gives an empty list. NWS Aviation Weather Center data, passed through unmodified and served by Eden Engine; not an official NWS or AWC product.
