The storm now began to undergo an extratropical transition with forward speed peaking at , the second-highest forward motion ever recorded in a tropical cyclone. Interacting with a baroclinic zone, the hurricane completed its transition at 1800 UTC on September 26, resulting in the issuance of the final advisory on the storm. As Tropical Storm Emily quickly approached the Windward Islands on September 21, a tropical storm warning was issued for Grenada, Barbados, St. Vincent and St. Lucia. A tropical storm watch was also declared for Martinique. As the storm tracked through the islands, all watches and warnings were discontinued later that day. Early on September 22, a hurricane warning was issued for the southern coast of the Dominican Republic and southern Haiti, including the southwestern peninsula. Upon attaining major hurricane status, a hurricane warning was declared for northern Haiti as the storm was anticipated to maintain hurricane intensity through landfall. Later that day, a hurricane watch was issued for the southeastern Bahamas and the Turks and Caicos Islands. This watch was later upgraded to a warning as the storm was expected to regain intensity over the Bahamas. Following the anticipation of a more westerly track on September 23, a hurricane watch was issued for the northwestern Bahamas, later superseded by a warning, and a hurricane warning was declared for eastern Cuba. Early on September 24, all watches and warnings for the Caribbean Islands, including the Bahamas, were discontinued as Emily moved out over the Atlantic Ocean. On September 25, a special advisory was issued for Bermuda as tropical storm-force winds were likely to impact the island. Following the unexpected intensification, another special advisory was issued stating that hurricane-force winds would impact the island during the day on September 25. This advisory was discontinued following the storms' passage later that day. Throughout the Windward Islands, schools and businesses were closed ahead of the storm. In the Dominican Republic, roughly 6,000 people were evacuated from Santo Domingo ahead of the storm. Although the storm never tracked towards Florida, state officials advised residents to prepare for the storm. Officials were in the "awareness stage" of hurricane preparation as they were discussing the possibility of impact from Emily. In the Turks and Caicos, residents were evacuated from low-lying areas to shelters throughout the islands. On September 25, the Canadian Hurricane Centre issued its first information bulletin ever related to a tropical cyclone as Emily was moving into Canadian offshore waters. The agency was created less than a month earlier, and warned for the potential of heavy rainfall and strong winds in the ocean southeast of Newfoundland.
