FIG. 3. Contrast of observed intense hurricane tracks between 1950 and 1990 from the 10 most active hindcast ( > 3.5 intense hurricanes and > 8.0 days of intense hurricanes occurring) seasons versus the 10 calmest hindcast seasons ( < 1.7 intense hurricanes and < 2.0 days of intense hurricanes occurring) from a 1 December of the previous year initial forecast date. The ratio of observed intense hurricane days between the two composites is 9.5 to 1.
