Weather Briefing

MVFR

Eloy Alfaro International Airport is currently reporting marginal VFR (MVFR) conditions with broken clouds at 2,300 feet and 10 miles or greater visibility.

Wind Analysis

Winds are from the south-southwest (200°) at 4 knots.

Visibility & Ceiling

Visibility is unrestricted. The ceiling is 2300 feet AGL (broken), placing conditions in the MVFR category.

Temperature & Moisture

Temperature is 25°C (77°F) with a dewpoint of 24°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. Conditions are expected to fluctuate between VFR and MVFR. VFR pilots should be prepared for deteriorating conditions.

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.

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