caption_attribution_description: English: Track map of Tropical Storm Olga of the 2007 Atlantic hurricane season. The points show the location of the storm at 6-hour intervals. The colour represents the storm's maximum sustained wind speeds as classified in the Saffir–Simpson scale (see below), and the shape of the data points represent the nature of the storm, according to the legend below.

context_page_description: Tropical Storm Olga was the fifteenth named storm of the 2007 Atlantic hurricane season. In the second week of December, after the official end of the hurricane season, a low formed east of the northernmost Lesser Antilles. It slowly gained tropical characteristics, and late on December 10, the NHC declared it Subtropical Storm Olga while just north of Puerto Rico. It is the first post-season storm since Tropical Storm Zeta in the 2005 season, making this season one of the few with activity both before and after the official bounds of the hurricane season. The storm made landfall on December 11 on the eastern tip of the Dominican Republic. Later that evening, Olga transitioned into a tropical storm just after making landfall. Olga tracked over Hispaniola and emerged in the Caribbean Sea. Strong wind shear and dry air caused Olga to weaken into a remnant low early on December 13.
  The storm impacted many areas affected by Tropical Storm Noel a month earlier. In Puerto Rico, moderate rainfall caused one death. 37 fatalities were confirmed in the Dominican Republic, including twenty deaths due to the release of floodgates at a dam in Santiago Province.
context_section_description: In the first week of December, a westward-moving upper-level low led to the formation of a broad surface trough well to the east of the northern Lesser Antilles. With a strong ridge to its northeast, the trough tracked slowly westward, creating scattered convection and some cyclonic turning. On December 8 convection began to persist in association with the trough and an upper-level low. Early on December 9, officials at the Tropical Prediction Center began classifying the system using the Hebert-Poteat technique, and several tropical cyclone forecast models expected its development of tropical characteristics. The system, which included of a sharp trough with an area of gale force winds to its north, continued westward through an area of moderately warm sea surface temperatures. On December 10 a low-level circulation developed within the system, though its convection had become disorganized and well-removed from the center. Southerly wind shear left the structure asymmetric, and convection steadily increased closer to the center. With an upper-level low situated just south of the center, the National Hurricane Center classified it as Subtropical Storm Olga at 0300 UTC on December 11 while located about 55 miles (85 km) east of San Juan, Puerto Rico.
  After being classified as a subtropical cyclone, Olga kept an organized outflow, and located to the southeast of a strong ridge over the western Atlantic Ocean, the cyclone moved west-southwestward. The storm strengthened a little bit while moving right along the north coast of Puerto Rico, and after an increase in convection near the center, Olga made landfall near Punta Cana, Dominican Republic at 1800 UTC on December 11. A Hurricane Hunters flight into the storm reported a tighter wind gradient and peak winds of 60 mph (95 km/h), and at 0000 UTC on December 12 the National Hurricane Center reclassified Olga as a tropical cyclone while it was still inland. Convection quickly weakened as the storm crossed central Hispaniola, and after reaching the Caribbean Sea the system lacked the convection required for the classification of a tropical cyclone; rainbands well to its northeast had stronger winds, though the center became very disorganized with dry air and strong wind shear. Late on December 12, convection increased a little bit over the center, though by that time the cyclone weakened to tropical depression status. As a certain amount of convection failed to exist, the National Hurricane Center discontinued advisories on Olga earlier on December 13 while located about 80 miles (130 km) northwest of Kingston, Jamaica. Its remnants continued west-northwestward with a clear low-level circulation, creating scattered thunderstorms over Cuba and the Cayman Islands with its moisture extending northward into southern Florida.
