Weather Warning

Rainy conditions this Friday

November 15, 2019
10.15 am

Diagnosis: Warm temperatures have been recorded this morning in various parts of the Central Valley (maximum between 25-28 ° C) and the Pacific (maximum between 27-32 ° C). Also, the entry of the western breeze has been presented to sectors near Alajuela, Heredia and sectors west of San José.

Forecast: During this afternoon and early hours of the night, isolated downpours are expected with possible storm for the Central Valley, the mountains and surroundings of the North Zone and the Nicoya peninsula with maximum accumulated between 20-40 mm. As for the Central and South Pacific, heavy rains and downpours with accumulated between 30-60 mm are anticipated, in addition, it is not ruled out that higher amounts can occur locally. On the other hand, scattered rains with estimated amounts between 10-20 mm are possible for mountainous parts of the Caribbean.

Warning: Recent analyzes show a high probability that a cold front is affecting the national territory, Sunday night and Monday being the most important period of affectation. This will be generating an increase in rainfall levels and their persistence in the regions of the Caribbean and the North Zone, as well as an increase in the speed of trade winds, which will be perceived mainly in the Cordilleras of the country and in lower parts of the Central Valley and Guanacaste. You will be followed up during this weekend.

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.
