Cindy Weakens to a Tropical Wave

Former Tropical Storm Cindy weakened to a tropical wave over the Atlantic Ocean south-southeast of Bermuda on Sunday night. At 11:00 p.m. EDT on Sunday the center of Tropical Wave Cindy was located at latitude 22.8°N and longitude 60.0°W which put it about 375 miles (605 km) north-northeast of the northern Leeward Islands. Former Tropical Storm Cindy was moving toward the northwest at 14 m.p.h. (22 km/h). The maximum sustained wind speed was 40 m.p.h. (65 km/h) and there were wind gusts to 50 m.p.h. (80 km/h). The minimum surface pressure was 1011 mb.

An upper level trough over the western Atlantic Ocean produced southwesterly winds that blew toward the top of former Tropical Storm Cindy’s circulation. Those winds caused strong vertical wind shear. The wind shear blew the tops off of new thunderstorms that started to form near the center of circulation. Thunderstorms were still occurring in bands in the eastern half of the circulation around former Tropical Storm Cindy. Bands in the western half of the circulation consisted primarily of showers and lower clouds. Winds to tropical storm force were occurring about 70 miles (110 km) northeast of the center of circulation. Winds in the other parts of former Tropical Storm Cindy were blowing at less than tropical storm force.

Former Tropical Storm Cindy will move through an environment unfavorable for intensification during the next 48 hours. Cindy will move over water where the Sea Surface Temperatures are near 28˚C. However, the upper level trough over the western Atlantic will cause strong vertical wind shear to continue for several more days. Former Tropical Storm Cindy could move into an area where there is less vertical wind shear in a couple of days. There is a slight chance that former Tropical Storm Cindy could strengthen when the wind shear decreases during the middle of the week.
