U.S. weather forecasters say Tropical Storm Dora – in the Pacific off southern Mexico – could reach hurricane strength by Tuesday night. The system, however, is expected to remain out to sea.

The National Hurricane Center in Miami says in its latest advisory Monday that Dora has wind speeds of 75 kilometers per hour. The tropical storm is currently 660 kilometers south-southeast of Salina Cruz, Mexico, moving west at 22 kilometers per hour.

Elsewhere, the Bahamian government has discontinued tropical storm warnings for Grand Bahama and the Abaco islands as a strengthening Tropical Storm Bret moves away from the Bahamas. The storm is currently moving north-northeast at 11 kilometers per hour with 100 kilometer-per-hour winds. Forecasters say Bret could grow into a hurricane by early Tuesday.

They add Bret could dump up to 10 centimeters of rain over the northwest Bahamas but the rains will diminish in the coming hours.
