Weather Briefing

LIFR

Del Norte International Airport is currently reporting low IFR (LIFR) conditions with overcast skies at 500 feet and 1 SM visibility. Note: This observation is 1.2 hours old and conditions may have changed.

Wind Analysis

Winds are from the east-southeast (110°) at 4 knots.

Visibility & Ceiling

Visibility is reduced to 1 SM. IFR conditions prevail and an instrument clearance is required for operations in controlled airspace. The ceiling is very low at 300 feet AGL (broken), well below circling minimums at most airports.

Temperature & Moisture

Temperature is 21°C (70°F) with a dewpoint of 20°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 14 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, Haze.

Pilot Recommendations

Current conditions require an instrument rating, IFR-equipped aircraft, and an IFR clearance. Check approach minimums carefully as conditions may be below CAT I ILS minimums. 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.
