Squall lines associated with the outer bands of a well defined disturbance that later became Sub-tropical Olga produced tropical storm force wind gusts across Saint Thomas. Several power outages were reported across the territory.

Road flooding was reported at Almirante Norte, Sector El Indio, Highway 22, exit 35 towards Highway 2, in the municipality of Vega Baja.

North Central, Puerto Rico · Heavy Rain · Dec 11, 22:21 UTC

Rainfall associated with tropical storm Olga saturated ground conditions across sections of Puerto Rico, which triggered an avalanche of mud and rock in the Dajaos sector, along Highway 167 from Bayamon to Naranjito, burying a sport utility vehicle, injuring the driver and killing its passenger.

San Juan and Vicinity, Puerto Rico · Debris Flow · Dec 12, 05:30 UTC

A housing annex worth $750,000 at the county jail was destroyed. The 125 female inmates living in the annex were evacuated before it was destroyed, resulting in zero injuries. There was also roof damage to a fire station, four vehicles were flipped and there were numerous trees and power poles downed.

A best track is the record a warning agency settles on after the storm, not what it said at the time: position, maximum sustained wind and central pressure every six hours, revised against every observation that came in later. Category is the Saffir-Simpson scale, which runs from Category 1 at 64 kt to Category 5 at 137 kt and reads wind only, so it says nothing about surge or rain. Accumulated cyclone energy adds up the square of the wind through the storm's life, so it counts strength and duration together.
