Weather Briefing

MVFR

Santa Bernardina International Airport is currently reporting marginal VFR (MVFR) conditions with broken clouds at 1,000 feet and 10 miles or greater visibility.

Wind Analysis

Winds are from the west-southwest (240°) at 10 knots. Runway 21 is favored with a 9-knot headwind and 5-knot crosswind component.

Visibility & Ceiling

Visibility is unrestricted. The ceiling is 1000 feet AGL (broken), placing conditions in the MVFR category.

Temperature & Moisture

Temperature is 13°C (55°F) with a dewpoint of 11°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: Fog. Temporary LIFR conditions are forecast with Fog between 06:00Z and 11:00Z.

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.
