A University of Costa Rica expert is predicting high seas with strong waves and possible flooding along the Pacific coast today and tomorrow.
The full moon also is a factor, said Omar G. Lizano Rodríguez of the Centro de Investigación en Ciencias del Mar y Limnología. He issued a warning Thursday.
In addition, the warning said that operators of small boats better think twice before heading out to sea. A major point of danger is where rivers discharge into the sea and meet the arriving waves, the warning said.
Lizano said a high pressure area over the south Pacific was part of the reason higher waves would be generated. The northern Pacific will be faced with rough and choppy seas generated by strong winds from the north, he said.
Some of the conditions are expected to last through Monday, he said.
Generally the waves will be in the two meter or six-foot neighborhood, said the warning.
In the central Pacific residents should be on guard between 3 and 5 p.m. for high seas and possible flooding, he said.
