Weather Briefing

MVFR

Tuktoyaktuk / James Gruben Airport is currently reporting marginal VFR (MVFR) conditions with broken clouds at 1,400 feet and 4 SM visibility.

Wind Analysis

Winds are from the east (80°) at 9 knots. Runway 10/28 is favored with a 8-knot headwind and 3-knot crosswind component.

Visibility & Ceiling

Visibility is 4 SM, below VFR minimums in some airspace classifications. Check local requirements before departing VFR. The ceiling is 1400 feet AGL (broken), placing conditions in the MVFR category.

Temperature & Moisture

Temperature is -3°C (27°F) with a dewpoint of -4°C. The temperature-dewpoint spread is very narrow, indicating saturated or near-saturated air. Fog formation or low cloud development is likely. Temperatures are at or below freezing. Check for icing conditions and ensure aircraft anti-ice/de-ice systems are operational if required.

Forecast Outlook

The TAF forecast covers the next 4 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 Snow, Light Showers Snow, FCST. Temporary IFR conditions are forecast with Light Snow between 01:00Z and 05:00Z. There is a 30% probability of IFR conditions with Light Showers Snow, FCST between 01:00Z and 05:00Z.

Pilot Recommendations

VFR pilots should exercise caution. Consider filing IFR if instrument rated, or postponing the flight if conditions are expected to deteriorate further. 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.
