Weather Briefing

VFR

Déline Airport is currently reporting visual flight rules (VFR) conditions with overcast skies at 4,100 feet and 20 SM visibility. Note: This observation is 7.5 hours old and conditions may have changed.

Wind Analysis

Winds are calm, presenting no crosswind concerns for any runway.

Visibility & Ceiling

Visibility is 20 SM. The ceiling is 4100 feet AGL (overcast), well above standard VFR minimums.

Temperature & Moisture

Temperature is 4°C (39°F) with a dewpoint of 2°C. The temperature-dewpoint spread is very narrow, indicating saturated or near-saturated air. Fog formation or low cloud development is likely.

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.

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