Weather Warning

Rain of varying intensity this afternoon and evening

November 21, 2023
10.30 a.m.

Discussion: Local factors such as morning warming, high humidity content and entry of sea breeze generate an unstable atmospheric pattern in our country, favoring ideal conditions for the occurrence of rainfall of varying intensity this afternoon and night.

Forecast: Rains of varying intensity and occasional heavy downpours with thunderstorms are expected in the afternoon; starting in the mountainous sectors of the Central and South Pacific, as well as in the Central Valley. For its part, in the Tempisque Valley, Nicoya Peninsula, Northern Zone and mountains of the Caribbean, isolated showers and storms are estimated. Cumulative estimates between 25-50 mm, maximums between 60-80 mm.

Rainy activity will extend into the night hours in regions of the Pacific and Central Valley. In addition, fog banks are possible in mountainous sectors.

Warning: Soil saturation continues with high percentages in the North Zone, North Caribbean and South Pacific, take extreme preventive measures.

Due to the above, the IMN recommends:

  • Caution due to sewage saturation and possible flash floods, as well as the main routes of the country in the event of heavy rain events.
  • Prevention against electrical storms and seeking shelter in a safe place in case strong gusts of wind occur or are perceived near storm clouds, due to the possible fall of tree branches, power lines, among others.
