Warnings the route crosses SIGMETs and AIRMETs whose area the line passes through or comes within 25 nm of

• SIGMET W17W: thunderstorms (a convective SIGMET) up to 30,000 ft, moving from the southwest at 20 knots, until 2:55 am PDT (09:55 UTC). Over the route from 369 to 428 nm out.

• AIRMET TANGO 1W: moderate turbulence above 18,000 ft from 18,000 ft to 39,000 ft. Over the first 179 nm of the route.
• AIRMET ZULU 2C: moderate icing up to 23,000 ft. Over the route from 239 to 727 nm out.
• AIRMET SIERRA 1E: mountains obscured by cloud (due to mountains obscured by clouds, precipitation, mist). Over the route from 259 to 767 nm out.
• AIRMET TANGO 1W: moderate turbulence below 18,000 ft (due to mountain wave) up to 12,000 ft. Over the route from 369 to 508 nm out.
• AIRMET TANGO 4W: moderate turbulence above 18,000 ft (due to mountain wave) from 34,000 ft to 43,000 ft. Over the route from 598 to 867 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 657 to 906 nm out.
• AIRMET TANGO 2W: moderate turbulence below 18,000 ft (due to mountain wave) up to 22,000 ft. Over the route from 717 to 827 nm out.
• AIRMET TANGO 5W: strong surface winds (30 knots or more) (due to sustained surface winds greater than 30 knots). Over the route from 727 to 787 nm out.
• AIRMET SIERRA 4E: low cloud or poor visibility (IFR conditions) (due to ceilings below 1,000 ft, visibility below 3 miles, precipitation, mist). Over the route from 867 to 1205 nm out.
• AIRMET TANGO 2W: 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 1345 to 1793 nm out.
• AIRMET SIERRA 3E: low cloud or poor visibility (IFR conditions) (due to ceilings below 1,000 ft, visibility below 3 miles, precipitation, mist, fog). Over the last 538 nm of the route.
• AIRMET TANGO 3W: moderate turbulence above 18,000 ft from 24,000 ft to 33,000 ft. Over the last 219 nm of the route.
• AIRMET SIERRA 4E: mountains obscured by cloud (due to mountains obscured by clouds, mist). Over the route from 2151 to 2331 nm out.
• AIRMET ZULU 1C: moderate icing from 12,000 ft to 24,000 ft. Over the last 100 nm of the route.

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.
