Weather Warning

Heavy rainy morning activity in the Caribbean and the North Zone

July 18, 2018
09.50 a.m.

Discussion: The increase in atmospheric pressure levels over the Caribbean Sea favor accelerated trade winds over the country and, in turn, the recurrent inflow of moisture from maritime sectors to the province of Limón and the North Zone, causing cloud growth and heavy downpours with storm electricity in these regions, with maximum accumulated between 50-80 mm in the last 6 hours. Part of the cloudiness and precipitation have spread to the Central Valley and north of Guanacaste with amounts less than 5 mm in the last 6 hours.

Forecast: In the remainder of the morning will be maintained rains of variable intensity and electrical storm in the regions of the Caribbean and the North Zone, are estimated accumulated between 20-40 mm with possible higher quantities locally. The cloud incursions to the Central Valley and north of Guanacaste will continue, generating occasional weak rains, amounts of less than 5 mm.

In the afternoon the rains tend to decrease gradually in the Caribbean and the North Zone, they can manifest themselves in isolation in the mountains, amounts between 5-15 mm. On the other hand, in the Central and South Pacific, isolated showers and thunderstorms are predicted in this period, especially in mountainous sectors, accumulated 20-40 mm. While in the Central and North Pacific Valleys the possibility of rain is low, it is manifested in the form of weak rain and drizzle in the mountains.

Occasional rains are possible in the Caribbean and the North Zone during the night.

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.
