Williston Basin International to Palm Springs International XWA → PSP

1,038 nautical miles (1,195 statute miles) southwest on a straight line, true course 218°, about 210° magnetic at the departure end (variation 8E). At 120 knots that is 9 h 37 min at the quickest height in today's winds (4,500 ft, a 12-knot headwind), arriving about 11:40 am PDT (18:40 UTC). 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: 1 flights in the DOT's last twelve reported months, the route's page.

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 XWA.

Based on data from the 12th at 06:00 UTC; valid on the 12th at 12:00 UTC for use 08:00 to 15:00 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.
