Category 4 Hurricane Cindy in the Atlantic

A tropical wave moved off the west coast of Africa on August 18, and it immediately began to organize with deep convection beginning to wrap around the center. The wave formed Tropical Depression Four later on the 18th when located about 250 miles ESE of the Cape Verde Islands. The system's development was originally hindered by harsh wind shear, and this kept the depression from retaining storm status until late on August 20 when it was named Tropical Storm Cindy. The storm continued almost due west as the rate of intensification increased, and it reached hurricane status late on August 21 when it was located about 390 miles west of the Cape Verde Islands. Hurricane Cindy could not strengthen further due to increasing wind shear, and it weakened back to a tropical storm on August 22. Cindy curved more to the WNW on the 22nd and it continued this motion through August 24, remaining a tropical storm all the while. On August 25, Cindy turned further to the north and shear also began to slacken at this time which allowed it to once again become a hurricane when located about 1100 miles southeast of Bermuda. At this point, conditions remained favorable and Cindy strengthened slowly at first, and reached Category 2 intensity on August 27.

The strengthening continued and Cindy was a large and powerful Category 4 storm on August 28 when it reached a peak intensity of 140 mph winds and a pressure of 942 mbar. Cindy was able to retain Category 4 intensity as it moved to the north until it began to weaken on the 29th due to cooler waters and increasing shear. The storm curved to the northeast and weakened to a Category 1 storm by August 30, and to a storm by early on the 31st. Tropical Storm Cindy merged with a large extratropical system over the North Atlantic later on the 31st when located about 850 miles west of the Azores. No damages or casualties have been reported due to Cindy, having never affected land throughout it's long trek through the Atlantic.
