High seas in the Pacific routed 35 families in Espíritu Santo de Caldera early Wednesday, and some houses were destroyed, said the national emergency commission.
The agency issued a warning for vacationers and those living along the coast that high seas will continue for the week.
The agency, the Comisión Nacional de Prevención de Riesgos y Atención de Emergencias specifically mentioned Palo Seco, Parrita, Playa Azul, Tárcoles, el Cocal de Quepos and Isla Damas as areas that might be subject to erosion as a result of the seas.
The commissions said that Alejandro Gutiérrez of Universidad
Nacional determined that the families that were displaced and forced to more to a public shelter had constructed their homes in the maritime zone. Gutiérrez is an oceanographer.
The commission also said that operators of small boats should take care.
Meanwhile there continues to be an area of unsettle air just off the Pacific coast. The low pressure area is generating showers and thunderstorms as it moves west at about 10 mph, said the U.S. Nacional Hurricane Center in Miami.
The Instituto Meteorológico Nacional is predicting afternoon thunderstorms today in the Central Valley and the Pacific coasts. There is a probability of morning rains in the northern zone and on the Caribbean coast, it said.
