Weather Briefing

VFR

Futenma Marine Corps Air Station is currently reporting visual flight rules (VFR) conditions with broken clouds at 6,000 feet and 10 SM visibility.

Wind Analysis

Winds are from the southeast (130°) at 13 knots with gusts to 20 knots. Runway 06/24 is favored with a 4-knot headwind and 12-knot crosswind component (gusting to 19 knots crosswind).

Visibility & Ceiling

Visibility is 10 SM. The ceiling is 6000 feet AGL (broken), well above standard VFR minimums.

Temperature & Moisture

Temperature is 28°C (82°F) with a dewpoint of 25°C. The narrow temperature-dewpoint spread suggests high humidity and potential for visibility restrictions, especially during cooling periods.

Forecast Outlook

The TAF forecast covers the next 24 hours. The forecast shows a transition between VFR and IFR conditions. Pilots should monitor the forecast closely and have an alternate airport plan. Expected weather includes: Light Showers Rain, Mist. Winds are forecast to reach up to 20 knots during the period. Temporary IFR conditions are forecast with Light Showers Rain, Mist between 07:00Z and 13:00Z.

Pilot Recommendations

Conditions are favorable for visual flight. The narrow temperature-dewpoint spread creates risk of fog formation, particularly during evening and early morning hours. The forecast indicates conditions may deteriorate. Ensure you have fuel reserves and a viable alternate airport.

This briefing is generated from real-time METAR and TAF data. Always verify with official sources before flight.
