The strongest activity has been presented on the Caribbean side; from midnight to 9:10 a.m. accumulated rainfall is recorded between 20-65 mm in this region. In that same period, in the Central Valley, mountains of the North Zone and Central and South Pacific, the amounts recorded range between 5-20 mm while in the North Pacific the amounts are less than 1 mm.

Forecast: During the morning it is expected that the rainy activity, especially the Caribbean, will continue to intensify; with accumulated that can reach between 30-40 mm in the remainder of the period, particularly the areas of Tortuguero, Guápiles, Siquirres, Liverpool, Four Miles and its surroundings can present the strongest activity. For the rest of the country the cloudy conditions will continue with intermittent and accumulated rains between 5-15 mm.

For the afternoon, it is expected that the intense rainy activity on the Caribbean will continue during the first hours and then more intermittently in the rest of the period, with accumulated between 20-30 mm. The mountainous parts of the North Caribbean and North Zone can present storms in a localized way.

For the Central Valley, intermittent rains of varying intensity will continue, in addition to possible showers with thunderstorms, punctually mainly to the west and in the vicinity of the mountains; the amounts are estimated between 10-40 mm.

For the Central and South Pacific regions, in addition to the Nicoya peninsula, intense rainy activity is expected, mainly near coastal regions, with maximum accumulated amounts between 50-100 mm and possible higher amounts locally.

For the night, the unstable conditions will remain on the country reason why isolated rains are anticipated on all the national territory.

For this weekend it is profiled that they continue the atmospheric instability over the region so it expects variable rainy activity over the whole country.


Due to the above, the IMN recommends:


    Caution in areas vulnerable to flooding due to sewer saturation, increased flow in rivers and streams, and in areas prone to landslides.
    Shelter in a safe place in case of hearing thunderstorms or perceiving strong gusts of wind near storm clouds, as well as precaution for possible fall of tree branches, power lines among others.
    Caution to drivers due to reduced visibility and wet roads.
