Tropical Storm Dorian pushed quickly westward across the Atlantic on Saturday, but forecasters said it was likely to weaken before nearing Caribbean islands.

National Weather Service meteorologist David Sanchez told The Associated Press that rough ocean conditions are expected on Monday, when the storm is expected to pass closest to Puerto Rico.

Remnants of a weakening Dorian were forecast to pass north of the Dominican Republic, Haiti and Cuba by early Thursday.

The storm had maximum sustained winds of 40 mph (65 kph) near midday Saturday and it was centered about 720 miles (1,160 kilometers) east of the northern Leeward Islands, moving west at 23 mph (37 kph).

In the Pacific, Tropical Storm Flossie was moving quickly west-northwest, heading toward Hawaii, though it was projected to weaken before reaching the islands. It had maximum sustained winds of 65 mph (100 kph) and was centered about 1,040 miles (1,675 kilometers) east of Hilo, Hawaii. It was moving west-northwest at 20 mph (32 kph).

There were no watches or warnings in effect for either storm.
