Weather Briefing

IFR

Limon International Airport is currently reporting instrument flight rules (IFR) conditions with broken clouds at 1,000 feet and 4 km visibility. Note: This observation is 15.8 hours old and conditions may have changed.

Wind Analysis

Winds are from the west (270°) at 5 knots. Runway 32 is favored with a 3-knot headwind and 4-knot crosswind component.

Visibility & Ceiling

Visibility is reduced to 4 km. IFR conditions prevail and an instrument clearance is required for operations in controlled airspace. The ceiling is 1000 feet AGL (broken), placing conditions in the MVFR category.

Temperature & Moisture

Temperature is 26°C (79°F) with a dewpoint of 26°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: Drizzle, Heavy Rain. Temporary IFR conditions are forecast with Heavy Rain between 09:00Z and 15:00Z.

Pilot Recommendations

An instrument rating and IFR flight plan are required. Verify that destination and alternate approach minimums are above current and forecast conditions. 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.
