Weather Briefing

IFR

Attawapiskat Airport is currently reporting instrument flight rules (IFR) conditions with overcast skies at 600 feet and 3 SM visibility.

Wind Analysis

Winds are from the south (170°) at 9 knots with gusts to 15 knots. Runway 24 is favored with a 3-knot headwind and 8-knot crosswind component (gusting to 14 knots crosswind).

Visibility & Ceiling

Visibility is 3 SM, below VFR minimums in some airspace classifications. Check local requirements before departing VFR. The ceiling is 600 feet AGL (overcast). Only precision approaches may be usable depending on minimums.

Temperature & Moisture

Temperature is 3°C (37°F) with a dewpoint of 3°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 4 hours. Conditions are expected to fluctuate between VFR and MVFR. VFR pilots should be prepared for deteriorating conditions. Expected weather includes: Light Rain, Light Rain, Mist, Light Rain, FCST, FCST. Temporary MVFR conditions are forecast with Light Rain between 16:00Z and 18:00Z. Temporary MVFR conditions are forecast with Light Rain, FCST, FCST between 18:00Z and 19:00Z.

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.
