SAN JUAN, Puerto Rico (AP) — Tropical Storm Bertha spun toward Puerto Rico and the Dominican Republic early Saturday after dumping heavy rain across the eastern Caribbean and causing several power outages in the region.

The storm had maximum sustained winds of 50 mph (85 kph), and no significant change in strength was expected over the next two days as Bertha followed a path taking it near Puerto Rico and possibly skirting over the Dominican Republic before heading for the Bahamas, the National Hurricane Center in Miami said. The storm was centered 275 miles (445 kilometers) southeast of San Juan and moving to the west-northwest at 22 mph (35 kph) late Friday.
