Weather Briefing

IFR

Yacuiba Airport is currently reporting instrument flight rules (IFR) conditions with overcast skies at 1,200 feet and 2 km visibility. Note: This observation is 1.9 hours old and conditions may have changed.

Wind Analysis

Winds are from the south (190°) at 3 knots.

Visibility & Ceiling

Visibility is reduced to 2 km. IFR conditions prevail and an instrument clearance is required for operations in controlled airspace. The ceiling is 1200 feet AGL (overcast), placing conditions in the MVFR category.

Temperature & Moisture

Temperature is 19°C (66°F) with a dewpoint of 18°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. 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: Drizzle.

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.

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