About 15,000 people remain isolated due to floods caused by pouring rains in Panama, the National System of Civil Protection (Sinaproc) said Tuesday.

Highways and roads in Bocas del Toro bordering with Costa Rica were flooded as Sixaola River roared. Many communities in the province were made isolated, the Sinaproc said.

Meanwhile, Luz Graciela Calzadilla, a meteorologist at the Electric Transmission Company, said that the effects of the cold front in Costa Rica would continue over the next 18 to 24 hours in Panama.

On Monday, the Panamanian authorities issued a green (preventive) alert in the provinces of Bocas del Toro, Chiriqui, Vergaguas and Colon, asking the inhabitants to be cautious.

In November last year, Panama's Darien province on the border with Colombia was hit by pouring rain, causing the rivers of Chunchunaque, Chico, Tupisa and Turqueza to overflow and making some 700 Panamanian families in the province threatened by hunger.
