Weather Warning

Unstable conditions in the country this Saturday

June 29, 2019.
08.45 am

Diagnosis: An unstable pattern generated by the Intertropical Convergence Zone and the influence of trade winds in the Caribbean Sea, at this time causes cloudiness and rainfall in the Caribbean regions and the North Zone of the country, generating accumulations of up to 100 mm in the last 8 hours in Tortuguero. In the rest of the country it has prevailed mostly cloudy with some rains, especially on the Pacific regions.

Forecast: In the remainder of this morning are expected isolated showers with accumulated between 15-30 mm in lapses of 3 hours and with possible storm in the North Zone and the North Caribbean, as for the Central Valley and the North Pacific will remain winds moderate and light rain in the mountains. In the rest of the country there will be partial cloudiness and warm temperatures.

During the afternoon and the first hours of the night, a reduction of the trade winds is estimated, which will favor the rains towards the Central and South Pacific regions, the Nicoya Peninsula and west of the Central Valley mainly, which could be strong in a localized manner generating maximum accumulated between 30-60 mm in periods of 6 hours. On the other hand, in the Caribbean and the North Zone the rains will be presented in the mountains with accumulated between 15-30 mm 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 an electrical storm or perceive strong gusts of wind near the storm clouds, as well as caution for possible fall of tree branches, power lines among others.
