Associated Press: MIAMI, USA — A tropical depression has formed in the central Caribbean Sea and forecasters say it is expected to become a hurricane in the coming days as it approaches Central America.

The US National Hurricane Center in Miami said Tropical Depression 29 emerged Saturday afternoon about 315 miles southeast of Kingston, Jamaica.

The Miami-based centre said the storm system is forecast to become a hurricane in a couple of days as it approaches Nicaragua and Honduras.

Forecasters said hurricane or tropical storm watches will likely be required for portions of both of those countries in the coming hours.

The depression is moving to the west at close to 15 miles per hour.

On the forecast track, the center of the storm is expected to be near the northeast coast of Nicaragua by Monday night.

The storm has top sustained winds near 35 miles per hour with higher gusts and is expected to dump heavy rains across parts of Jamaica and Central America, raising the risk of flash flooding and river flooding.

Forecasters said that if the depression becomes a named storm as expected, it would be named Eta as the 28th named Atlantic storm this season — tying the 2005 record for named storms.
