Tropical Storm Olga has claimed the lives of at least eight people as it lashed the Dominican Republic Wednesday.

The northern province of Santiago in the Caribbean nation was hardest hit, with heavy rains causing the Yaque River to overflow its banks. In addition to widespread flooding, the storm is being blamed for several landslides.

Olga had earlier passed through Puerto Rico, where it is being blamed for killing one man. It later skirted Haiti, which shares the island Hispaniola with the Dominican Republic. Haitian authorities have not reported any serious injuries.

Weather forecasters say the storm is likely to weaken as it passes out over open water.

Olga comes nearly two weeks after the official end of the Atlantic hurricane season.

The season began June 1 and ended November 30.
