Winds of up to 60 kph (37 mph) are expected in Guanacaste and the Central Valley starting today. This is being caused by an increase in atmospheric pressure in the Caribbean Sea, said the Instituto Meteorológico Nacional.
The winds are expected to build to a peak Thursday. Coupled with these conditions is an expected increase in rain on the Caribbean coast and in the northern zone, said the institute. Predicted are rains there today of from 30 to 80 millimeters or from one to three inches.
These conditions are expected to last to the weekend. The weather institute warned of slides and flooding both on the Caribbean coast and on the Pacific.
