8 ft (2.4 m). In the United Kingdom, the storm caused downed trees and power lines, as well as flooded rivers. Tropical Depression Five This tropical depression formed in the eastern tropical Atlantic Ocean on August 31. The depression moved west-northwest, then northwest away from the Caribbean Sea without further development before dissipating east-southeast of Bermuda on September 4. Tropical Depression Six A tropical wave crossed the Caribbean sea, moving into a favorable upper environment in the western Caribbean sea on August 31. The system formed into a weak tropical depression before crossing the Yucatán peninsula, becoming better organized as it moved into the south-central and western Gulf of Mexico between September 1 and 3. The system moved ashore east-central Mexico before quickly dissipating as a tropical cyclone on September 4. Satellite imagery revealed that its residual cloud pattern persisted over Mexico for an additional couple of days before degenerating. Heavy rainfall fell primarily north of its track, with the maximum across northeast Mexico falling at El Barranco/Altamira, where a total of was measured. Tropical Storm Danielle On September 1, a tropical wave moved off the coast of Africa and headed westward. The disturbance was below the 10 degree latitude as it organized into a tropical depression on September 7 and then a tropical storm later that day. Danielle peaked as a storm on September 8, while Reconnaissance Aircraft reported gusts of up to hurricane force. After passing through the Lesser Antilles, Danielle encountered vertical wind shear, and on September 10 it dissipated in the central Caribbean. The remnants continued westward and ultimately regenerated into Tropical Storm Lester. The islands of Saint Vincent and the Grenadines experienced wind gusts up to hurricane force, causing severe power outages and causing roof damage. In the Grenadines, the storm drove a coast guard ship aground, while five people were injured and hundreds of homes were destroyed. Torrential rainfall produced several mudslides, which, in turn, damaged roads, bridges, electricity, and water services. Danielle also destroyed twelve homes on the island of Barbados. In Trinidad and Tobago, strong flooding of up to four feet caused 27 landslides, destroying four bridges. The storm caused $8 million in damage in Tobago. Total damage from the storm amounted to $9.2 million (1986 USD), mostly to crops, though no deaths were reported. Hurricane Earl The strongest storm of the season began as a tropical wave off Africa on September
