The rescue agency said that the Río Parrita was likely to run out of its banks. The agency said it was sending two trucks and a special vehicle into the area to assist with the evacuation.
The situation in Parrita is in addition to the estimated 123 persons who are in shelters. Mainly in the Nicoya peninsula and the area around Golfito.
The national weather service said that the country would be getting rain for 48 hours at least. The blame was being placed on Tropical Depression 12 that is just off the coast of southeastern México. However, yet another area of thunderstorms and showers has developed in the Caribbean and is associated with a broad low pressure area, said the U.S. National Hurricane Center in Miami, Florida.
The center said that the system has a low chance of developing into anything stronger in the next 48 hours. However, it said that locally heavy rains will likely continue over Central America. The center warned of life-threatening flash floods and landslides.
The Ministerio de Obras Públicas y Transportes released a long list of highways and roads that have suffered damage. Most have reduced but not blocked passage. Seven municipal routes were closed completely by slides. They were in Puriscal, Coto Brus, Parrita and Aserrí.
In San Miguel de Aserrí some 1,400 persons were without water due to the rupture of a pipe. In Orotina, there was a similar problem.
Because of the low pressure area in the Caribbean, the northern zone and the Caribbean coast will be getting rain and thundershowers today.
The Asociación Nacional de Productores Arroceros de Costa Rica postponed a meeting planned for today to inspect the rice field in the Province of Limón.
The Consejo Nacional de Vialidad said in the late afternoon that heavy rains were obstructing repairs of the Interamericana Norte at Kilometer 82 in el Empalme or Cambronero. Trucks were being detoured to Ruta 27, the new Caldera highway. The agency urged others to consider taking the same route. However, it said it expected to restore passage at that point later Thursday night.
