Rainy activity for this afternoon

april 23, 2020.
11:10 am

Diagnosis: The weakening of the trade wind has allowed the entry of moisture from the Pacific Ocean to national territory throughout this morning, this, together with the high temperatures registered on the Pacific side, generates favorable conditions for rainy activity this afternoon.

 

Forecast: For this afternoon and early evening, isolated showers are expected for the Central and South Pacific regions, mainly in the border area with Panama, the Osa Peninsula and mountainous areas. For the Central Valley scattered rains are expected mainly in the vicinity of the upper parts, in addition it is possible to have an occasional thunderstorm in the north and west.

On the other hand, significant rainfall is not expected in the Caribbean and Northern Zone during this period.

Due to the above, the IMN recommends:

  •     Caution in areas vulnerable to flooding due to sewerage saturation, especially in the South Pacific and Central Pacific regions.
  •     Take refuge in a safe place in case of hearing an electrical storm or perceiving strong gusts of wind near the storm clouds, as well as precaution for possible fall of tree branches, power lines, among others.
