Weather Briefing

VFR

El Tari Airport is currently reporting visual flight rules (VFR) conditions with few clouds at 2,000 feet and 10 miles or greater visibility.

Wind Analysis

Winds are from the east-southeast (110°) at 15 knots. Runway 12/30 is favored with a 15-knot headwind and 3-knot crosswind component. Student pilots and low-time aviators should exercise caution.

Visibility & Ceiling

Visibility is unrestricted. No ceiling exists. Cloud layers reported: few at 2,000 ft.

Temperature & Moisture

Temperature is 32°C (90°F) with a dewpoint of 17°C, indicating relatively dry conditions. High temperatures at this elevation may result in significant density altitude effects. Pilots should calculate density altitude and adjust performance expectations accordingly.

Forecast Outlook

The TAF forecast covers the next 24 hours. Conditions are expected to fluctuate between VFR and MVFR. VFR pilots should be prepared for deteriorating conditions. Temporary VFR conditions are forecast between 03:00Z and 07:00Z.

Pilot Recommendations

Conditions are favorable for visual flight. 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.
