Tropical Storm Olga developed over the Gulf of Mexico and Tropical Storm Pablo formed near the Azores on Friday afternoon. At 5:00 p.m. EDT on Friday the center of Tropical Storm Olga was located at latitude 26.3°N and longitude 93.2°W which put it about 260 miles (420 km) south of Lake Charles, Louisiana. Olga was moving toward the north-northeast at 18 m.p.h. (30 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 998 mb.
A reconnaissance plane found that former Tropical Depression Seventeen had strengthened by Friday afternoon and the National Hurricane center designated the system as Tropical Storm Olga. More thunderstorms developed near the center of Olga and the plane found that the minimum surface pressure had decreased to 998 mb. Bands of showers and thunderstorms were also developing around the tropical storm. The strongest rainbands were in the eastern half of the circulation. Bands in the western half of the circulation consisted of more showers and lower clouds. Storms near the center were generating upper level divergence which was pumping mass away to the northeast of Tropical Storm Olga. Winds to tropical storm force extended out about 90 miles (145 km) from the center of circulation in the northeastern quadrant of Olga.
Tropical Storm Olga could strengthen a little more during the next 12 hours. Olga will move over water where the Sea Surface Temperature is near 28°C. An upper level trough over the south central U.S. and Mexico will produce southwesterly winds which will blow toward the top of the circulationn. Those winds will produce moderate vertical wind shear, which will inhibit intensification. However, the shear will not be strong enough to prevent intensification while the Olga is over the Gulf of Mexico. The wind shear will cause Tropical Storm Olga to start a transition to an extratropical cyclone. A cold front will move toward Olga from the northwest and the tropical storm could merge with the front during the next 24 hours.
The upper level trough will steer Tropical Storm Olga toward the north during the next several days. On its anticipated track Olga will make landfall on the coast of Louisiana during Friday night. Tropical Storm Olga will bring gusty winds to coastal Louisiana. Olga is likely to drop heavy rain over parts of Louisiana, Mississippi, and eastern Arkansas. The rain could cause floods in some locations.
Elsewhere over the Atlantic Ocean, visible satellite images revealed that a tiny tropical storm had developed at the center of a much larger low pressure system west of the Azores on Friday afternoon. The National Hurricane Center designated the system as Tropical Storm Pablo. At 5:00 p.m. EDT on Friday the center of Tropical Storm Pablo was located at latitude 35.8°N and longitude 32.2°W which put it about 325 miles (525 km) west-southwest of the Azores. Pablo was moving toward the east-southeast at 10 m.p.h. (16 km/h). The maximum sustained wind speed was 45 m.p.h. (75 km/h) and there were wind gusts to 60 m.p.h. (95 km/h). The minimum surface pressure was 990 mb. Winds to tropical storm force extended out 35 miles (55 km) from the center of Tropical Storm Pablo.
