Weather Briefing

MVFR

Bizerte Sidi Ahmed Air Base is currently reporting marginal VFR (MVFR) conditions with few clouds at 2,000 feet and 6 km visibility.

Wind Analysis

Winds are from the north-northeast (30°) at 13 knots. Runway 08/26 is favored with a 8-knot headwind and 10-knot crosswind component.

Visibility & Ceiling

Visibility is 6 km, below VFR minimums in some airspace classifications. Check local requirements before departing VFR. No ceiling exists. Cloud layers reported: few at 2,000 ft.

Temperature & Moisture

Temperature is 16°C (61°F) with a dewpoint of 15°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 9 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: Mist. There is a 30% probability of IFR conditions with Mist between 18:00Z and 22:00Z.

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.
