Q: Question: What country was Dolly closest too when she was named a tropical depression? Passage:On August19, 2014, a tropical wave emerged off the west coast of Africa. The system traversed the Atlantic over the next week with no signs of development. Convection finally increased once the wave entered the Caribbean Sea on August27; however, it was not until August30 when interaction with a Kelvin wave spurred organization. An area of low pressure consolidated within the system as it crossed the Yucatan Peninsula on August31. Formation of a banding feature along the southeastern portion of the circulation on September1 marked the system's transition into a tropical depression by 18:00UTC while over the Bay of Campeche. Although situated over warm waters of , strong wind shear created an unfavorable environment and hindered intensification. During this formative stage, the depression tracked northward as its center relocated before turning to the northwest and later west. It was uncertain if a closed circulation truly existed due to conflicting data and the depression could have remained a trough until the afternoon of September2.
