Weather Briefing

LIFR

Cape Romanzof LRRS Airport is currently reporting low IFR (LIFR) conditions with overcast skies at 400 feet and 10 SM visibility.

Wind Analysis

Winds are from the south (180°) at 20 knots. Runway 20 is favored with a 19-knot headwind and 7-knot crosswind component. Student pilots and low-time aviators should exercise caution.

Visibility & Ceiling

Visibility is 10 SM. The ceiling is very low at 400 feet AGL (overcast), well below circling minimums at most airports.

Temperature & Moisture

Temperature is 8°C (46°F) with a dewpoint of 8°C. The temperature-dewpoint spread is very narrow, indicating saturated or near-saturated air. Fog formation or low cloud development is likely.

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.

About Cape Romanzof LRRS Airport

Overview

Cape Romanzof LRRS Airport serves a critical communication and navigation role in western Alaska, located at 61.780300, -166.039002. The medium-sized airport sits at an elevation of 464 feet MSL, providing essential infrastructure in a remote region with challenging environmental conditions. Its Long Range Radio Range Station (LRRS) designation indicates significant strategic communication capabilities.

Flying Conditions

Weather at Cape Romanzof demonstrates significant variability, with Visual Flight Rules (VFR) conditions predominating at 59.3% of observations. Temperature ranges dramatically from -28°C to 7°C, with an average of -7.2°C, presenting potential icing and performance challenges. Wind conditions are notably strong, with prevailing northerly winds averaging 21 knots and capable of reaching up to 75 knots, requiring robust pilot preparation.

Notable Features

The single runway 02/20, measuring 3,990 feet and constructed of gravel (GVL), offers consistent wind alignment with 100% favorable wind conditions. The airport's geographic position in western Alaska implies rugged terrain and potential rapid weather transitions. Calm wind conditions occur in only 4.5% of observations, suggesting consistent atmospheric movement in the region.

Approach Considerations

Pilots should anticipate potential crosswind landings, with an average crosswind of 8.5 knots on runway 02/20. Visibility averages 9.3 statute miles, though 2.3% of observations feature visibility below 3 miles and 1.7% include fog conditions. September, December, and January statistically offer the most favorable Visual Flight Rules conditions for operations.
