MIAMI -- New named storms have formed far out over the Atlantic and Pacific, though neither poses a threat to land.

The U.S. National Hurricane Center in Miami says the Atlantic's Subtropical Storm Ernesto had maximum sustained winds Wednesday near 40 mph (65 kph) with some additional strengthening is possible over the next day.

It's centred about 650 miles (1,045 kilometres) southeast of Canada's Cape Race, Newfoundland, and is moving north near 9 mph (15 kph).

Meanwhile, the Pacific's Tropical Storm Lane is 1,285 miles (2,065 kilometres) southwest of the southern tip of the Baja California Peninsula and is heading west at 13 mph (20 kph).

It had winds of 45 mph (75 kph) Wednesday and forecasters say it might grow become a hurricane on Thursday.
