ridge and slowly intensified. While the depression was well west of Cape Verde, it intensified into Tropical Storm Cesar on August 2. Cesar continued on the generally northwestward path and no significant change in intensity occurred, as it peaked at 50 mph (85 km/h) shortly after becoming a tropical storm. Later in its duration, wind shear significantly increased, causing the low-level circulation to be removed from the deep convection on August 6, and Cesar weakened back to a tropical depression as a result. As it was weakening to a tropical depression, Cesar became nearly stationary, and turned abruptly eastward. On the following day, Cesar dissipated almost 1,150 mi (1,850 km) east-southeast of Bermuda. Tropical Storm Edouard A frontal wave formed near the Azores in early August. When thunderstorm activity grew near its center, it was deemed a subtropical depression on August 2 just east of the Azores. Associated with an upper-level cold low, it intensified into a subtropical storm on August 3, although water temperatures were cooler than what is usually required for tropical cyclogenesis. It tracking westward and passed near Graciosa before weakening back to a depression on August 4. The depression executed a small cyclonic loop, developing deep and organized convection near the circulation. Late on August 6, it transitioned into Tropical Depression Six. The depression moved northeastward toward the Azores, intensifying into Tropical Storm Edouard on August 8. Shortly thereafter it reached peak winds of , and subsequently it moved past the northern Azores. On August 10, Edouard weakened again to depression status, and became extratropical on the following day. The remnants of Edouard dissipated on August 13, a few hundred miles west of Portugal. Much of the western Azores reported winds of at 35 mph (55 km/h). The island of Horta reported winds gusts from 35 to 65 mph (55 to 100 km/h). Lajes Air Force Base on Terceira Island reported a maximum wind gust of . Also a tower on the island of Terceira reported sustained winds at 50 mph (80 km/h), while a gusts as high as were recorded. Hurricane Diana A tropical wave uneventfully crossed the Atlantic Ocean and entered the Caribbean Sea either late July or early August 1990. As the system entered the southwest Caribbean, it began to further develop, and became Tropical Depression Five on August 4. The depression headed northwestward, and intensified enough to be upgraded to Tropical Storm
