Low pressure over Costa Rica caused some heavy rains Sunday, but the amount was variable.
Showers and thunderstorms associated with a tropical wave were in a disorganized system off the Pacific coast of Nicaragua, said the U.S. National Hurricane Center. The weather experts there estimated that the system has about a 30 percent chance of becoming a tropical storm, but the direction was westward away from land.
The Instituto Meteorológico Nacional put out a bulletin Sunday night warning of evening storms. But the recorded rain fell short of the predicted 80 millimeters, more than three inches.
La Fortuna came close. The automatic weather stations there registered 71.2 millimeters or about 2.8 inches. Santa Rosa in Guanacaste registered 34.6 millimeters, some 1.26 inches. But Liberia did not show any rain at all.
Both San José and Ciudad Colón had about an inch. The city experienced moderate thunder and lightning.
