Flight planning: Benjamin Taisacan Manglona International GRO / PGRO
What a pilot looks at before a flight from or to Benjamin Taisacan Manglona International in Rota Island, Northern Mariana Islands, in plain English: right now VFR: good flying weather, Wind calm. The warnings, reports and winds below come from the government's aviation weather service and the restrictions from the FAA, refreshed every few minutes. For planning, not a briefing: the legal preflight briefing comes from Flight Service (1-800-WX-BRIEF) or the FAA's own tools.

Warnings in force SIGMETs and AIRMETs whose area covers this field
No SIGMET or AIRMET covers this field right now.
Turbulence No turbulence warning in force over this field. No pilot has reported turbulence within 100 nautical miles in the last three hours. The government's turbulence forecast map ↗
Icing No icing warning in force over this field. No pilot has reported icing within 100 nautical miles in the last three hours. The government's icing forecast map ↗
A SIGMET warns of weather hazardous to all aircraft (thunderstorms, severe turbulence or icing, volcanic ash); an AIRMET of weather that matters to small aircraft and to flying without instruments (moderate turbulence or icing, low cloud, strong surface wind, mountains hidden in cloud). An area is counted when it covers this field's position.
Pilot reports within 100 nautical miles, last three hours, nearest first
Not fetched just now.
What pilots in the air told air traffic control or Flight Service: turbulence, icing, cloud tops and bases, temperature, wind, and whatever they remarked on (wind shear on final, a smooth ride). An urgent report is one of severe turbulence or icing, wind shear, or similar. Open "as filed, and in English" for the coded report and its translation line by line.
Winds and temperatures aloft forecast
No winds-aloft forecast point could be matched to this field just now.

From the FAA's notice service (NOTAMs), the site's copy refreshed every few minutes; last checked a minute 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.
Radar and forecast charts government pictures, the latest each time the page loads





The radar pictures come from the National Weather Service (the nearest radar, then the region); the aviation forecast charts from the Aviation Weather Center's Graphical Forecasts for Aviation (clouds and visibility; surface wind, weather and thunderstorms with the AIRMET boxes); the surface analysis and the 12- and 24-hour forecast charts from the Weather Prediction Center. They are public-domain government images shown as they are published. The turbulence and icing forecasts are drawn live on the Aviation Weather Center's site: turbulence ↗ · icing ↗.
Sources: the Aviation Weather Center's data service (SIGMETs, AIRMETs, graphical AIRMETs, pilot reports, winds and temperatures aloft), the National Weather Service radar, the Weather Prediction Center's charts, and the FAA's temporary flight restriction list and shapes. Fetched when the page is viewed and kept a few minutes. Back to Benjamin Taisacan Manglona International, where the current observation and the forecast for the field are.
