Tropical Storm Dorian 2013 Watch: Winds Increase To Almost 60 Mph (95 Kph) In Atlantic, Heads Towards Puerto Rico And Virgin Islands This Weekend

Tropical Storm Dorian is being closely watched by weather forecasters as it continues to gain strength while moving across the Atlantic. The storm is far from land, but may head towards Puerto Rico and the Virgin Islands this weekend.

Early Thursday, the storm's maximum sustained winds increased to near 60 mph (95 kph), ABC News reports.

Tropical Storm Dorian is located about 700 miles (1,125 kilometers) west of the Cape Verde Islands, off the coast of west Africa, and is moving west-northwest near 17 mph (28 kph).

Dorian will stay over open waters through most of the weekend, but may approach the longitude of Puerto Rico, the Virgin Islands, and Leeward Islands from Sunday night to Monday, Weather.com reports.

However, the website states that it is more likely the tropical storm will head north of those islands. Some fringe effects are possible in the area and may pose land threats, even if the center of the storm tracks north.

According to Weather.com, it is too soon to either rule out or speculate a U.S. threat by the storm.

The storm has a 20 percent chance of developing further over the next two days, due to a low-pressure area about 300 miles east of Bermuda, which the hurricane center is monitoring, The Christian Post reports.

Another storm, Tropical Storm Flossie, has formed over the Pacific. According to The Christian Post, Flossie's maximum sustained winds are near 40 mph (65 kph), and will slowly strengthen over the next day or two.

Flossie is centered about 1,045 miles (1,685 kilometers) west-southwest of the southern tip of Mexico's Baja California and is moving west-northwest near 15 mph (24 kph).
