Tropical Storm Beta appears to have bypassed the Colombian island of San Andres, but forecasters say it could strengthen into a hurricane as it approaches the island of Providencia.
The National Weather Service says a hurricane warning is in effect for the Colombian island of Providencia, off the coast of Nicaragua. Beta is currently some 80 kilometers northeast of San Andres, moving north at about seven kilometers per hour.
The storm is expected to turn northwest and strengthen, possibly to hurricane strength, during the next 24 hours.
Forecasters say the center of the storm could reach mainland Nicaragua by Sunday. Beta is expected to dump as much as 38 centimeters of rain across Honduras, Nicaragua, San Andres and Providencia.
