maintained hurricane force winds until around 1200 UTC on 23 August. The weakening storm turned toward the west and moved along the northern coast of Hispaniola. Although the mountainous landmass of that island may have played some role in the weakening by restricting inflow from the south and disrupting the southern part of the cyclone's circulation, it appears that vertical shear was primarily responsible. Around midday on 23 August, a distinct low-cloud circulation center was evident just to the north

.During the 1975 season 63% of the hurricanes had winds100 kt or greater and the highest sustained speed was125 kt. The duration of hurricane force winds in 1977totaled 128 h compared with 498 h in 1975. Storm windsin 1977 totaled 343 h and those in 1976 816 h. The 1977 tropical cyclone season was exceptional inthat one of the hurricanes (Doreen) became the second'such storm within a year to bring heavy rains to Southern California.

is of great help in assessing system location and organization. The SeaWinds scatterometer onboard the National Aeronautics and Space Administration's Quick Scatterometer (QuikSCAT) satellite ( Tsai et al. 2000 ) provides surface winds over large oceanic swaths. While the QuikSCAT does not have the horizontal resolution to determine a cyclone's maximum winds, it can be used to estimate the extent of tropical storm force winds, and is often helpful in determining whether an incipient tropical
