Impacts throughout the Windward Islands were substantial, but most heavily concentrated in St. Lucia. There, gusts reached , toppling trees and power lines. Torrential rainfall up to 26.3 in (668 mm) created mudslides and landslides that damaged or destroyed numerous structures, bridges, and vehicles. Most of the island's plantain and banana crops were destroyed. Up to 14 people were killed. Farther west in Curaçao, Tomas led to the most prolific rain event in four decades. An elderly man was killed after suffering a heart attack and drowning in his flooded vehicle, while a rescue worker died after a hospital wall collapsed. In Haiti, already ravaged by a catastrophic 7.0 MW earthquake less than a year prior, heavy rainfall flooded a refugee camp and triggered mudslides that destroyed homes and roads. Up to 35 people were killed there, though it was feared many more could die as Tomas exacerbated an already-deadly cholera outbreak.
