Hurricane Dorian of 2019 Political Alerts!

On August 19, 2019, the National Hurricane Center (NHC) identified a tropical wave—an elongated trough of low air pressure—within a monsoon trough over Guinea and Senegal in western Africa. Convective activity associated with the wave was limited by an abundance of Saharan dust in the region. Propagating west over the tropical Atlantic Ocean, the system remained disorganized for several days. On August 23, a defined area of low pressure consolidated at the surface and thunderstorm activity increased. The system acquired sufficient organized convection to be classified as Tropical Depression Five at 15:00 UTC on August 24. At this time the system was situated 805 mi (1,300 km) east-southeast of Barbados. A deep ridge imparted continued westward movement of the depression, steering it toward the Lesser Antilles. A small cyclone, it soon developed a defined inner-core with a 12 mi (18 km) wide eye-like feature. This marked the system's intensification into a tropical storm, at which time it was assigned the name Dorian by the NHC. Thereafter, moderate wind shear and surrounding dry air limited further organization. Rainbands gradually wrapped more around Dorian on August 25–26, though convection remained inconsistent.
