Meteorological warning

Afternoon of intense rains for the Central and South Pacific

13 june, 2019.
9:50 am

Diagnosis: An increase in the intensity of the trade wind over the north and center of the country due to the increase in atmospheric pressure over the Caribbean Sea generated rainy conditions in the Caribbean and Northern regions during the early hours of the day and also decreases the income of humidity from the Pacific to national territory.


Forecast: For this afternoon and early evening, conditions of isolated downpours with a localized thunderstorm are anticipated for the mountainous sectors of the Central Pacific and the South Pacific with estimates of accumulated precipitation between 30-50 mm, however, higher amounts may be given in a localized way.

For the mountainous parts of the Central Valley, the North Zone, the mountains of the Caribbean and the Nicoya Peninsula, some scattered showers of short duration with amounts between 5-20 mm are possible. No significant rainfall is expected for the rest of the country. In the case of the North Zone and the Caribbean, rainfall can also occur during the night period.

Due to the above, the IMN recommends:

    Caution in areas with vulnerability to flooding due to saturation of sewers, increased flow in rivers and streams and sectors with high propensity to landslide. Special attention to the North Zone, Central Valley and North Pacific.
    Shelter in a safe place in case of listening to thunderstorm or perceive strong gusts of wind near storm clouds, as well as caution for possible fall of tree branches, power lines among others.
