• AIRMET TANGO 1W: moderate turbulence above 18,000 ft from 18,000 ft to 39,000 ft. Over the first 90 nm of the route.
• AIRMET TANGO 1W: moderate turbulence below 18,000 ft (due to mountain wave) up to 15,000 ft. Over the route from 130 to 300 nm out.
• AIRMET SIERRA 1E: mountains obscured by cloud (due to mountains obscured by clouds, precipitation, mist). Over the route from 300 to 639 nm out.
• AIRMET TANGO 4W: moderate turbulence below 18,000 ft up to 18,000 ft. Over the route from 310 to 909 nm out.

• AIRMET TANGO 1W: low-level wind shear (due to air speed loss or gain of 20 knots or more below 2,000 ft above the ground). Over the route from 629 to 789 nm out.
• AIRMET TANGO 2W: moderate turbulence above 18,000 ft from 35,000 ft to 45,000 ft. Over the route from 729 to 869 nm out.
• AIRMET SIERRA 1E: mountains obscured by cloud (due to mountains obscured by clouds, precipitation, mist). Over the route from 769 to 809 nm out.
• AIRMET TANGO 3W: low-level wind shear (due to air speed loss or gain of 20 knots or more below 2,000 ft above the ground). Over the route from 889 to 1059 nm out.

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 SFO.

Temporary flight restrictions on the line or within 25 nm of it

• 6/7231 Santa Clara, CA, Sunday, October 11, 2026 through Monday, October 12, 2026 UTC 14 nm from the route, at the departure end · drones kept away from a public gathering · until 12 October · ZOA

Daylight

Sunset at SFO 6:36 pm PDT (01:36 UTC), at GCM 6:50 pm CDT (23:50 UTC) (civil twilight ends 7:15 pm CDT (00:15 UTC)). At 120 knots the arrival at GCM is before sunrise there (7:26 am CDT (12:26 UTC)).

Each restriction opens the FAA's own page with the exact area, heights and times. Ordinary notices to air missions (closed runways, lights out) are not shown: the FAA's notice search is not open to sites like this one at this time.
