Another run of high waves is expected to hit the Pacific coast today and last for three days.
The high seas are generated by a storm near New Zealand, said Omar Lizano of the Centro de Investigación en Ciencias del Mar y Limnología at the Universidad de Costa Rica.
This is a similar problem that some residents of the area faced five days ago.
The national emergency commission is taking steps and has issued a small boat warning and a warning to bathers. The high waves are expected to be about 20 to 22 seconds apart and are expected to be strong, said the Centro.
Last week a section of Caldera near Puntarenas suffered flooding, and some of the residents are moving from the area for good. They are being relocated in Esparza. Sand, carried by the waves, accumulated in the rooms. In some cases, the rooms that were below grade were nearly filled.
The areas where the greatest impact is expected are Caldera, Playa Azul and Corralillo de Tárcoles, Palo Seco and Isla Damas, said the Comisión Nacional de Prevención de Riesgos y Atención de Emergencias. The commission said that river mouths are particularly dangerous in these situations.
