Diagnosis: The passage of the tropical wave # 4 yesterday added to the influence of the Intertropical Convergence Zone on the country generates unstable atmospheric conditions that are manifested by rains and storms located in the Caribbean regions during this morning.


Forecast: In the remainder of this morning it is expected that the rains continue in the South and North Caribbean with amounts between 10-30 mm and possible higher quantities in a localized manner. These precipitations can extend and reach the plains of San Carlos and Guatuso and eastern part of the Central Valley, but less intensely with amounts between 5-10 mm.

For this afternoon, isolated rains are expected in addition to possible thunderstorms located in the Central and South Pacific regions, as well as in the Nicoya Peninsula and Central Valley with accumulated rainfall amounts in 6-hour periods between 30-50 mm. . In a timely manner higher amounts can be given.

In addition, during the afternoon and early evening in the regions of the North Caribbean, the mountainous North Zone and the border with Nicaragua, some isolated rains are possible with amounts between 10-30 mm accumulated in periods of 6 hours.

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.
  •     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.
