Flight planning: Ravalli County HRF / KHRF

What a pilot looks at before a flight from or to Ravalli County in Hamilton, Montana, in plain English: right now VFR: good flying weather, Wind from the southeast (140°) at 8 knots. 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

AIRMET TANGO 1W: moderate turbulence above 18,000 ft from 18,000 ft to 39,000 ft.

Turbulence AIRMET in force: moderate turbulence from 18,000 ft to 39,000 ft. 1 pilot report of turbulence within 100 nautical miles in the last three hours: moderate chop turbulence above 35,000 ft, 73 nm north, 2:04 pm MDT (20:04 UTC). The government's turbulence forecast map ↗

Icing No icing warning in force over this field. 2 pilot reports of icing within 100 nautical miles in the last three hours: light icing, at 9,000 ft, 39 nm north, 1:05 pm MDT (19:05 UTC); light rime icing, at 15,000 ft, 65 nm southeast, 2:57 pm MDT (20:57 UTC). The freezing level is below 9,000 ft, the lowest forecast height, so any cloud could carry ice. 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.

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 point DLN, 89 nm southeast of the field · for use 20:00–03:00 UTC

Based on data from the 12th at 18:00 UTC; valid on the 13th 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; the lowest rows are left out where the ground is already that high.

Temporary flight restrictions within 50 nautical miles, from the FAA's list

6/8927 Kalispell, MT, Wednesday, October 14, 2026 through Wednesday, October 14, 2026 Local 10 nm north · a VIP movement · starts Wednesday 14 October · ZSE
6/8923 Kalispell, MT, Wednesday, October 14, 2026 through Wednesday, October 14, 2026 Local 10 nm north · a VIP movement · starts Wednesday 14 October · ZLC
6/9020 Missoula, MT, Wednesday, October 14, 2026 Local 38 nm north · security · starts Wednesday 14 October · ZLC

Each restriction opens the FAA's own page with the exact area, heights and times. Ordinary notices to air missions (a closed runway, lights out, a crane) are not shown here: the FAA's notice search is not open to sites like this one at this time, and the application for the FAA's data feed is in hand.
