The state power company said that brush and forest fires have damaged some of its communication lines in Guanacaste and the Nicoya peninsula.
The communities include Tambor, Flamingo, Cuajiniquil and La Cruz, it said. Fiber optic cables have ruptured from the heat, and radio towers for cell and fixed telephone lines have been damaged as well as internet connections, the company, Instituto Costarricense de Electricidad, said Wednesday.
The country has been hit with multiple forest, brush and field fires to the extent that the national emergency commission has declared an alert.
Rain in parts of the country did no more than settle the dust.
The company said that complete repairs would not be possible until the fires had been controlled. The emergency commission blamed the outbreak on vegetation dried out by continual drought and the annual dry season.
