The Instituto Meteorológico Nacional estimated rainfall at up to 100 millimeters or about 4 inches in a 7 p.m. bulletin Thursday.
The agency issued a warning about rising rivers, including the ríos Yorkin, Telire, Sixaola and Pacuare on the Caribbean coast. Also rising are the Colorado, Cariblanco and María Aguilar Sarapiquí, the weather agency said.
