Survey Scores - Nassau MOS continues to tumble in the rankings!
Lessons Learned - Nassau • A TC passing west of a location (in the Tropics) generally does not produce as much rain or wind. • Very low ceilings are not common in the Tropics at sea level • The temperature change with the storm passage reflected some advection of air from the FL peninsula • Cb’s are a wild card with the TC’s.
