Tropical Storm Cindy (2011)

Storm Active: July 20-23

On July 19, a low pressure center formed along a stationary frontal boundary situated over the central Atlantic, in the vicinity of Bermuda. This front was the same one that spawned Tropical Storm Bret. The low quickly moved to the east, and deepened over the next day. On July 20, its circulation became increasingly disassociated with the frontal boundary, and the appearance of deep central convection was enough to name the system Tropical Storm Cindy that afternoon.

Even as it formed, it began to accelerate northeastward at speeds over 20 mph. Cindy strengthened rapidly as the circulation became better defined, developing a proto-eye feature early on July 21. The cyclone reached its peak winds, 70 mph, during that morning, and maintained its tropical characteristics through the day. The winds began to decrease as Cindy passed over the cold water north of the 40ºN parallel, but the pressure dropped from 1002 to 1000 mb. Additional drops in pressure despite negative changes in wind speed is often a symptom of a cyclone entering extratropical transition, which Cindy did on July 22. However, Cindy's convection was rapidly deteriorating by that afternoon, and the system continued to weaken, becoming a minimal tropical storm by late that night. Cindy was downgraded to a remnant low before actually becoming extratropical early on July 23. The remnant low of Cindy dissipated later the same day, causing no damage.
