Table 6. Comparison of the frequency of intense-, hurricane and all hurricane tracks in the vicinity of various U.S. coastal locations (Fig. 7) during the ten wettest versus the ten driest early-season (prior to 1 August) West Af rican rainfall years between 1949 and 1990 and the probability (or P value) of no wet-versus-dry relationship.
