Weather Briefing

MVFR

Alas Leuser Airport is currently reporting marginal VFR (MVFR) conditions with scattered clouds at 1,900 feet and 5 km visibility.

Wind Analysis

Winds are from the south (180°) at 3 knots.

Visibility & Ceiling

Visibility is 5 km, below VFR minimums in some airspace classifications. Check local requirements before departing VFR. No ceiling exists. Cloud layers reported: scattered at 1,900 ft.

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. Expected weather includes: Haze.

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.

About Alas Leuser Airport

Overview

Alas Leuser Airport serves the Kutacane region in Indonesia, situated at an elevation of 419 feet above mean sea level. As a medium-sized airport located at coordinates 3.391456, 97.863726, it provides essential aviation infrastructure for the local area and supports regional transportation needs.

Flying Conditions

The airport's moderate elevation and tropical location suggest potential for variable weather conditions typical of Indonesian mountainous regions. Pilots should anticipate potential humidity, thermal variations, and localized weather phenomena that can impact visibility and wind conditions around the 5,358-foot asphalt runway.

Notable Features

The single runway (15/33) is oriented in a northwest-southeast direction, which may interact with local terrain and wind patterns. The surrounding geography appears to be mountainous, which could introduce complex local wind dynamics and potential turbulence during approach and departure phases.

Approach Considerations

Runway 15/33 offers a substantial 5,358-foot asphalt surface, providing adequate length for most regional aircraft operations. Given the airport's mountainous location, pilots should prepare for potential terrain-influenced wind shear and be prepared to conduct careful wind assessments during arrival and departure procedures.
