MVFR — visibility 3.7 SM. Light winds at variable/1 kt, visibility 3.7 SM, a few at 2,000 ft. Would drop to IFR below 1,000 ft ceiling or 3 SM visibility, or rise back to VFR above 3,000 ft and 5 SM.

GMMI · day 17 at 07:00 UTC · wind variable at 1 kt · visibility 3.7 SM · a few clouds at 2,000 ft · temp 19°C / dewpoint 18°C · altimeter 29.97" Hg

// Density altitude · ISA +5°C
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.
