Wider weather episode

Delta first developed into a tropical depression in the Caribbean just south of Jamaica on the afternoon of October 4th. As it tracked across the western Caribbean, it rapidly intensified into a Category 4 hurricane. In fact, intensifying from tropical depression to Category strength in 40 hours is the fastest rate of intensification of any storm on record in the Atlantic Basin. Delta quickly weakened to a category 1 hurricane after making its first landfall on the Yucatan Peninsula. It gradually recurved north towards the Louisiana coastline, fluctuating in intensity between Category 2 and 3. Hurricane Delta ultimately arrived with an intensity of 105 mph, strong category 2 storm.
