Weather Briefing

MVFR

Plan De Guadalupe International Airport is currently reporting marginal VFR (MVFR) conditions with clear skies and 3 SM visibility. Note: This observation is 8.2 hours old and conditions may have changed.

Wind Analysis

Winds are from the northeast (50°) at 5 knots. Runway 03/21 is favored with a 5-knot headwind and 2-knot crosswind component.

Visibility & Ceiling

Visibility is 3 SM, below VFR minimums in some airspace classifications. Check local requirements before departing VFR. Skies are clear with unlimited ceiling.

Temperature & Moisture

Temperature is 16°C (61°F) with a dewpoint of 14°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: Mist, Fog, Haze. Temporary LIFR conditions are forecast with Fog between 10:00Z and 14:00Z.

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.
