Times are UTC (Z); the time after a slash is the local time at the airport. Weather and runway data come from the NOAA Aviation Weather Center (aviationweather.gov) and are refreshed here every few minutes; the plain-English summaries are generated by cwsi.net and may simplify, so the raw METAR and TAF are authoritative. Runway headings are true, worked out from NOAA's runway alignment. cwsi.net is not affiliated with NOAA or the FAA: get an official weather briefing before flight.
