Bellingham International to Purdue University Airport BLI → LAF

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

• AIRMET TANGO 1W: moderate turbulence above 18,000 ft from 18,000 ft to 39,000 ft. Near the route, 319 nm along the route.
• 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 1077 to 1107 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). Near the route, 1456 nm along 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 BLI.

Pilot reports along the route within 50 nm of the line, last three hours, the serious ones first

• E170 at 24,000 ft, 38 nm east, 9:50 pm PDT (04:50 UTC): light chop turbulence from 24,000 ft to 28,000 ft. At the destination end, 38 nm east of the line.

From the FAA's notice service (NOTAMs), the site's copy refreshed every few minutes; last checked 2 minutes ago. The FAA has so far issued eFlight its test feed, which misses some notices (checked against the FAA's own search on 12 October: about a third missing at Santa Barbara and Burbank, none at Atlanta or Las Vegas); the request for the full feed is with the FAA. Times are local to the field. This is for planning; the legal briefing comes from Flight Service or the FAA's own tools.
