What happened

The episode as NWS SJU wrote it up.

Dean became tropical depression four on the morning of August 13th when it was about 2000 miles east of the Lesser Antilles. On August 14th the depression increased its strength and was upgraded to Tropical Storm Dean when it was located about 1490 miles east of the Lesser Antilles. The storm continued to intensify and on August 16th at 5 am was upgraded to hurricane status, with maximum winds of 75 mph. Then it was located about 590 miles east of Martinique. At 5 pm on August 16th, a tropical storm watch was issued for Puerto Rico and the U.S Virgin Islands, at 11 pm, the tropical storm watch for Puerto Rico and the U.S. Virgin Islands was upgraded to a tropical storm warning. Dean continued to intensify during Friday August 17th,and by 2 am Saturday August 18th, its maximum sustained winds had increased to near 150 mph. It maintained its westward track through Saturday morning, when at 11 am the tropical storm warning for the U.S. Virgin Islands and Puerto Rico was discontinued. Most of local effects associated with the passage of Hurricane Dean south of the U.S. Virgin Islands and Puerto Rico were in association with the extreme outer rain bands along the northern part of the hurricane and the extensive radius of sustained tropical storm force winds. Sustained tropical storm-force winds likely occurred over most of the Saint Croix and Puerto Rico near shore waters. Although no sustained tropical storm force winds were officially observed in any of the sensors at the airports in Saint Croix and Puerto Rico, tropical storm force winds gusts were observed. Very likely the higher elevations of Saint Croix and Puerto Rico experienced sustained tropical storm force winds. The maximum ASOS-measured peak wind gusts included 46 mph at the Saint Croix airport, 41 mph at the Saint Thomas Airport, 44 mph at Ceiba Airport, and 36 mph at the Carolina Airport. Other unofficial wind gust measurements included 59 mph at the NOAA Crews Salt River Bay Station in Saint Croix, 58 mph at Hess Oil Refinery, and 46 mph at the NOAA Crews Station at La Parguera, in Lajas, Puerto Rico. Damage was limited to fallen trees, utility lines downed by wind gusts Friday night. Some coastal access roads around Saint Croix sustained moderate to higher damage due to beach erosion.
