On August 15, a tropical wave emerged into the tropical Atlantic ocean. It moved west-northwestward over the next few days and produced disorganized shower activity as part of a large area of unsettled weather which included both it and another disturbance several hundred miles to its west-southwest. Both systems developed low pressure centers, but their progress toward becoming tropical cyclones was hindered by their proximity. The western system ultimately became Tropical Storm Gert. By that time, the eastern low was producing gale-force winds, but the circulation was not well-defined enough to yet be named. That changed on August 20, when it finally became Tropical Storm Emily.
By the time Emily was named, its window of opportunity to strengthened had already closed. Wind shear and drier air overwhelmed the system, stripping it of any deep convection by early morning on August 21. Later that morning, it became a post-tropical cyclone, only one day after forming. What was left of the storm tracked northwest for several more days. Along the way, it encountered somewhat more favorable atmospheric conditions, but it could not take advantage of them to the point of redeveloping.
Emily was a sheared tropical storm during its brief existence.
Most of the track shown here shows when Emily was not a tropical cyclone (triangle points). It was only a tropical storm for a day (circle points).
