All barge access for hauling sand and stones were destroyed.
The airport also sustained some damage.
Seven boats ran aground during the storm.
Minor damage was reported in Anguilla.

In Puerto Rico, a man died after he collapsed from cardiac arrest while trying to install storm shutters on his home.
As a tropical wave, the precedent to Omar produced heavy rains over the island, causing minor flooding.
After passing by Puerto Rico a second time, Omar produced locally heavy rains, which caused minor street flooding.

On St. Croix, waves up to 15 ft (4.6 m) from Omar sank about 47 boats, leading to a large oil spill around the islands.
About 400 ships broke lose from the docks, 200 of which lost their anchors.
Omar produced upwards of 7 in (180 mm) of rain on the island within a 24‑hour span.
