LIFR — ceiling 300 ft. Moderate winds at 210°/11 kt, gusting 30, visibility 1.0 SM, broken at 300 ft, broken at 4,200 ft, and overcast at 10,000 ft. Reported weather: heavy rain and haze (+RA HZ). Haze is fine dust, salt, or pollution particles suspended in dry air — it reduces visibility and washes out contrast, a dry particulate obscuration rather than a moisture one. Note that automated stations can't chemically tell smoke from haze — during a regional smoke event, this may in fact be drifting wildfire smoke reported as haze. LIFR is the lowest standard category. Would improve to IFR above 500 ft and 1 SM.

Approximate using ~10% perf loss / 1,000 ft DA for normally aspirated, scaled by powerplant type. Verify with your aircraft's POH for accurate numbers — especially above 5,000 ft DA where these rules of thumb diverge. Severity rating assumes a standard altimeter setting (29.92" Hg / 1013 hPa); a non-standard setting shifts the effective altitude by roughly 1,000 ft per 1" Hg of deviation.
