Portland International Jetport to Buffalo Niagara International PWM → BUF

370 nautical miles (426 statute miles) west on a straight line, true course 266°, about 281° magnetic at the departure end (variation 15W). At 120 knots that is 3 h 10 min at the quickest height in today's winds (4,500 ft, a 3-knot headwind), arriving about 1:17 am EDT (05:17 UTC), after sunset at the destination. Right now PWM is marginal VFR, wind calm; BUF is VFR, wind from the east-northeast (060°) at 6 knots. For planning, not a briefing: the legal preflight briefing comes from Flight Service (1-800-WX-BRIEF) or the FAA's own tools. Airlines fly this pair: 3 flights in the DOT's last twelve reported months, the route's page.

The route the straight line, the warnings crossed, restrictions, pilot reports and the airports along the way · click a mark for its words

Green, blue, red and purple airport dots are the flying conditions reported there now (VFR, marginal VFR, IFR, low IFR); grey means no report. Red areas are SIGMETs, orange areas AIRMETs, hatched red areas temporary flight restrictions. Map tiles: OpenFreeMap, data © OpenStreetMap contributors.

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

AIRMET ZULU 1C: moderate icing up to 22,000 ft. Over the first 263 nm of the route.
AIRMET TANGO 3W: moderate turbulence above 18,000 ft from 21,000 ft to 33,000 ft. Over the whole route.
AIRMET TANGO 2W: moderate turbulence below 18,000 ft up to 13,000 ft. Over the first 234 nm of the route.
AIRMET SIERRA 3E: low cloud or poor visibility (IFR conditions) (due to ceilings below 1,000 ft, visibility below 3 miles, precipitation, mist). Over the route from 10 to 292 nm out.
AIRMET SIERRA 4E: mountains obscured by cloud (due to mountains obscured by clouds, precipitation, mist). Over the route from 39 to 253 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 PWM.

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

A333 at 15,000 ft, 33 nm south, 9:37 pm EDT (01:37 UTC): moderate chop turbulence up to 15,000 ft, remarks: during the climb. 29 nm along the route, 33 nm south of the line.

Winds aloft along the route, and the time en route the forecast for use 20:00–03:00 UTC · at 120 knots true airspeed

The westbound cruising heights for this course (VFR: even thousands plus 500 ft; above 18,000 ft the forecast levels), with the wind averaged along the line from the 5 forecast points nearest it (PWM, BML, ALB, SYR, BUF). A plus sign is a headwind, a minus sign a tailwind.

Based on data from the 11th at 18:00 UTC; valid on the 12th at 00:00 UTC for use 20:00 to 03:00 UTC; temperatures above 24,000 ft are below zero. Heights are above sea level; a height is left out when the forecast has no wind for it over most of the line (the ground is higher). Ground speed is the airspeed less the headwind; the time en route is for the straight line and ignores climb, descent and routing around weather.
