Weather Briefing

MVFR

Senai International Airport is currently reporting marginal VFR (MVFR) conditions with scattered clouds at 1,800 feet and 5 km visibility.

Wind Analysis

Winds are from the south (170°) at 7 knots. Runway 16/34 is favored with a 7-knot headwind and 1-knot crosswind component.

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: few at 1,700 ft (CB), scattered at 1,800 ft. Caution: cumulonimbus (thunderstorm) clouds reported at 1,700 ft AGL, indicating convective activity in the area.

Temperature & Moisture

Temperature is 28°C (82°F) with a dewpoint of 25°C. The narrow temperature-dewpoint spread suggests high humidity and potential for visibility restrictions, especially during cooling periods.

Forecast Outlook

The TAF forecast covers the next 23 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: Thunderstorm Rain. Temporary IFR conditions are forecast with Thunderstorm Rain between 07:00Z and 10:00Z.

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.
