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

• 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 590 to 1050 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 1170 to 1349 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 1190 to 1349 nm out.
• AIRMET TANGO 2W: moderate turbulence below 18,000 ft (due to mountain wave) up to 22,000 ft. Over the route from 1239 to 1329 nm out.
• AIRMET TANGO 5W: strong surface winds (30 knots or more) (due to sustained surface winds greater than 30 knots). Near the route, 1329 nm along the route.
• AIRMET ZULU 2C: moderate icing up to 23,000 ft. Over the route from 1349 to 1579 nm out.
