MEXICO CITY, Nov 21 (Reuters) - Tropical storm Otto formed in the Caribbean on Monday and could strengthen into a hurricane bound for southeastern Nicaragua and northeastern Costa Rica, the U.S.-based National Hurricane Center said.
The almost-stationary storm was about 175 miles (282 km) east-southeast of the island of San Andres, the NHC said, with maximum sustained winds of 50 miles per hour (80 kph).
"Additional strengthening is forecast during the next 48 hours, and Otto could become a hurricane during the next couple of days." the NHC said.
The storm could reach the coast of Nicaragua and Costa Rica by Thursday, the NHC said. (Reporting by Veronica Gomez; Editing by Meredith Mazzilli and Jonathan Oatis)
