• AIRMET TANGO 1W: moderate turbulence above 18,000 ft from 18,000 ft to 39,000 ft. Over the first 210 nm of the route.
• AIRMET ZULU 2C: moderate icing up to 23,000 ft. Over the route from 250 to 730 nm out.

• AIRMET SIERRA 4E: mountains obscured by cloud (due to mountains obscured by clouds, mist). Over the route from 2109 to 2269 nm out.
• AIRMET ZULU 1C: moderate icing from 12,000 ft to 24,000 ft. Near the route, at the destination end.

A SIGMET warns of weather hazardous to all aircraft; an AIRMET of weather that matters to small aircraft and to flying without instruments. "From 60 to 180 nm out" is measured along the route from STS.
