Hurricane Edouard gained strength in the Atlantic Monday but remained too far from land to pose a danger, US weather forecasters said.

Edouard has developed into a category two storm, with sustained winds of 165 kilometers (103 miles) per hour, the Miami, Florida-based National Hurricane Center said.

The five-point Saffir-Simpson scale rates the most powerful storms as category five.

Edouard is expected to gain power over the next 48 hours, but remain far from land. It was 1,055 kilometers (655 miles) southeast of Bermuda at 1500 GMT.

Edouard is the fourth hurricane of the Atlantic season. The third, Cristobal, left at least four dead and caused severe flooding when it slammed the Caribbean last month.

US weather authorities have revised earlier forecasts for the season, which ends in November, and now believe storm activity will be lower than average this year.

In the Pacific, meanwhile, Hurricane Odile lashed the coast of Mexico, dumping heavy rains and triggering massive waves, and is also expected to gain strength.
