The origins of Hurricane Olga were from the interaction of a cold front and a small weather disturbance in the north Atlantic Ocean, producing an extratropical low east of Bermuda on November 22.

[5] The eye steadily became better defined as outflow increased,[6] and on November 27, Olga attained peak winds of 90 mph (140 km/h), along with a minimum pressure of 973 mbar (28.73 inHg).

While at peak intensity, the hurricane executed a double loop about 455 mi (732 km) east of Bermuda, due to interaction with a larger cyclonic circulation that was isolated from the westerlies.

[1] Forecasters anticipated continued weakening until dissipation, although the cyclone was expected to move over an area of more favorable conditions, including warmer waters and lighter shear.

[1][9] It continued producing a small area of deep convection, prompting one forecaster to note that "Olga is stubbornly holding on to tropical cyclone status... for now.

"[10] After reaching a position about 240 mi (390 km) northeast of the Turks and Caicos Islands, the depression turned toward the north after a trough created a weakness in the ridge.

[12] By late on December 2, the structure resembled that of a hurricane with an eye in the center, and although convection was weak, Olga was able to intensify further to winds of 45 mph (72 km/h).

Later that day, the circulation turned to the southeast as a ridge built to its north, and Olga degenerated into a remnant low pressure area, about 690 mi (1,110 km) east of Nassau, Bahamas.

The remnant circulation turned to the south and west, completing a loop and later moving through the Bahamas before dissipating along the north coast of Cuba on December 7.

[1] Forecasters at the National Hurricane Center began issuing advisories on Olga on November 24 anticipating that the storm would threaten shipping lanes in the Atlantic.
