The probability is that Semana Santa will be a quiet time for family reunions, relaxation and recreation.
But various agencies are saying this is no time to put down the guard.
Volcán Turrialba appears to have quieted down after more than a week of eruptions. But the scientists who study volcanoes are not so sure. They still think the mountain may not respect the Semana Santa holidays.
Scientists who study the oceans said Wednesday that the Pacific coast is about to experience high seas again.
The strong seas crashing against the Pacific beaches represent a serious threat to bathers, said the Centro de Investigación en Ciencias del Mar y Limnología. The announcement said that the seas are expected to diminish by Sunday.
The Caja Costarricense de Seguro Social warned about holiday food. The usual Semana Santa fare typically is a lot of fish and other sea food. Without proper storage and preparation these foods are highly prone to creating intoxication, the Caja said Wednesday.
Such sea food is especially vulnerable to changes in temperature and incorrect storage methods, said Carolina Castro Calvo, a Caja nutritionist.
She said dehydrated cod, which is a Semana Santa standard can harbor fungus or bacteria if the original storage methods were not correct. Safety begins with buying fresh food and doing so from outlets that guarantee the condition of the food, she added.
Then there is the traffic. Police are out in force because holiday traffic usually results in accidents and personal tragedies.
The Cruz Roja said it is erecting 148 first aid stations around the country.
The Servicio Nacional de Guardacostas will have 25 of its boats on patrol off popular beaches. The Servicio de Vigilancia Aérea will have up to four aircraft in the skies, said the security ministry.
