Weather Briefing

VFR

El Tari Airport is currently reporting visual flight rules (VFR) conditions with scattered clouds at 1,700 feet and 9 km visibility.

Wind Analysis

Winds are from the east-southeast (110°) at 6 knots. Runway 12/30 is favored with a 6-knot headwind and 1-knot crosswind component.

Visibility & Ceiling

Visibility is 9 km. No ceiling exists. Cloud layers reported: scattered at 1,700 ft.

Temperature & Moisture

Temperature is 25°C (77°F) with a dewpoint of 21°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: Rain. There is a 30% probability of IFR conditions with Rain between 05:00Z and 09:00Z.

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.
