TS Cindy struggling with wind shear, likely to dissipate in the next day or so; regeneration possible

Tropical Storm Cindy, which peaked with maximum sustained winds of 60 mph yesterday, has weakened today as it feels the effects of southwesterly shear.

As of 11:00 a.m. EDT Sunday, Tropical Storm Cindy was centered near 20.9°N 58.0°W, and was moving northwestward at approximately 17 mph. Maximum sustained winds were 40 knots (45 mph), with an estimated minimum pressure of 1009 mb. Cindy consists of a disorganized, fully exposed low-level circulation with disorganized convective activity to its east. It already appears as if Cindy’s low-level circulation center is losing definition, and Cindy is likely to lose its status as a tropical cyclone within the next 24 hours. Cindy is struggling with the effects of approximately 30 knots (35 mph) of southwesterly wind shear, which should result in the cyclone opening up into a trough later today or tomorrow morning. In a few days, there are some indications in model runs that wind shear could relax slightly and Cindy could regenerate, but recent model runs have seemingly trended weaker with this idea. Regardless, Cindy will need to be monitored for possible regeneration, as it is possible Cindy or its remnants could bring effects to Bermuda and Atlantic Canada. However, if Cindy does manage to regenerate, it is not likely to intensify significantly due to fairly cool sea surface temperatures cooler than 26°C (78.8°F).
