Tropical Storm Bret moved near Barbados on Thursday afternoon. At 2:00 p.m. EDT on Thursday the center of Tropical Storm Bret was located at latitude 13.4°N and longitude 58.9°W which put it about 45 miles (75 km) east-northeast of Barbados. Bret was moving toward the west at 14 m.p.h. (22 km/h). The maximum sustained wind speed was 65 m.p.h. (105 km/h) and there were wind gusts to 80 m.p.h. (130 km/h). The minimum surface pressure was 1002 mb.

Tropical Storm Warnings were in effect for Barbados, St. Lucia, Martinique, Dominica and St. Vincent and the Grenadines. A Hurricane Watch was also in effect for St. Lucia.

The intensity of Tropical Storm Bret appeared to peak on Thursday morning. A U.S. Air Force Reserve Hurricane Hunter aircraft found that Bret was close to hurricane intensity on Thursday morning. A microwave satellite image showed an eyelike feature in the middle levels of Tropical Storm Bret. After its intensity peaked in the morning, the portion of Bret’s circulation in the lower levels appeared to race out ahead (to the west) of the parts of the circulation in the middle and upper troposphere during Thursday. The rapid movement of the circulation near the surface was creating strong vertical wind shear. The lower level circulation consisted primarily of showers and lower clouds. Thunderstorms were occurring in bands the eastern part of Tropical Storm Brett. Those thunderstorms were occurring near the circulation center in the middle levels.

The distribution of wind around Tropical Storm Bret remained asymmetrical. Winds to tropical storm force extended out 115 miles (185 km) in the northern side of Bret’s circulation. Winds to tropical storm force extended out 45 miles (75 km) in the southern part of Tropical Storm Bret.

Tropical Storm Bret will move through an environment unfavorable for intensification during the next 24 hours. Bret will move over water where the Sea Surface Temperatures are near 28˚C. It will move under the western end of an upper level ridge over the tropical Atlantic Ocean. The ridge will produce southerly winds that will blow toward the top of Bret’s circulation. Bret will move around the southern side of a subtropical high pressure system over the Atlantic Ocean. The subtropical high will produce strong easterly winds in the lower levels of the atmosphere. The strong easterly winds in in the lower levels will cause strong vertical wind shear. The strong wind shear will cause Tropical Storm Bret to weaken during the next 24 hours.

Tropical Storm Bret will move south of a subtropical high pressure system over the Atlantic Ocean. The subtropical high will steer Bret toward the west during the next 24 hours. On its anticipated track, Tropical Storm Bret will bring gusty winds and locally heavy rain to Barbados on Thursday afternoon. The center of Bret could pass close to St. Lucia on Thursday night. Tropical Storm Bret will bring strong winds and locally heavy rain to St. Lucia. Bands in the northern part of Bret’s circulation will also bring strong winds and locally heavy rain to Martinique and Dominica. Tropical Storm Bret could produce gusty winds and heavy rain over St. Vincent and the Grenadines. Locally heavy rain could cause flash floods in some locations.

Elsewhere over the Atlantic Ocean, Tropical Depression Four formed halfway between Africa and the Lesser Antilles. At 11:00 a.m. EDT on Thursday the center of Tropical Depression Four was located at latitude 11.3°N and longitude 42.9°W which put it about 1270 miles (2040 km) east of the Lesser Antilles. Tropical Depression Four was moving toward the west-northwest at 15 m.p.h. (24 km/h). The maximum sustained wind speed was 35 m.p.h. (55 km/h) and there were wind gusts to 45 m.p.h. (75 km/h). The minimum surface pressure was 1007 mb.
