Weather Briefing

IFR

Yaoundé Nsimalen International Airport is currently reporting instrument flight rules (IFR) conditions with broken clouds at 600 feet and 6 km visibility.

Wind Analysis

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

Visibility & Ceiling

Visibility is 6 km, below VFR minimums in some airspace classifications. Check local requirements before departing VFR. The ceiling is 600 feet AGL (broken). Only precision approaches may be usable depending on minimums. Caution: cumulonimbus (thunderstorm) clouds reported at 1,600 ft AGL, indicating convective activity in the area.

Temperature & Moisture

Temperature is 23°C (73°F) with a dewpoint of 21°C. The temperature-dewpoint spread is very narrow, indicating saturated or near-saturated air. Fog formation or low cloud development is likely.

Forecast Outlook

The TAF forecast covers the next 24 hours. IFR conditions are expected to persist or develop. An instrument rating and IFR flight plan are recommended. Expected weather includes: Light Thunderstorm Rain, Thunderstorm Rain. Temporary IFR conditions are forecast with Thunderstorm Rain between 10:00Z and 12:00Z.

Pilot Recommendations

An instrument rating and IFR flight plan are required. Verify that destination and alternate approach minimums are above current and forecast conditions. 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.
