Tropical Storm Danny is expected to have no effect on Costa Rica unless there is an unexpected change in its course.
The storm is over the Leeward Islands and headed directly towards Santo Domingo in the Dominican Republic, according to the U.S. National Hurricane Center.
Danny became the first Atlantic hurricane of the season but has since weakened to a tropical storm.
Danny is expected to produce 2 to 4 inches of rain over the Leeward Islands, the U.S. and British Virgin Islands and Puerto Rico through Tuesday, said the hurricane center.
Tropical-storm-force winds extend outward up to 105 miles (165 km) to the northeast of the center, according to the hurricane center.
The storm appears to be headed due west at about 15 mph.
Hurricanes that reach lower latitudes in the Caribbean can bring heavy rains to Costa Rica because the influence of the storms extend more than a hundred miles from the center.
Locally, the Instituto Meteorológico Nacional said that humid and unstable conditions predominate. The weather institute reported heavy rains and thunderstorms in the Pacific and the Caribbean mountains Sunday night.
More storms are predicted for today in the south and central Pacific. There may be isolated showers in the northern zone and the metro area, the institute said.
