Weather Warning

Favorable conditions for heavy rains this Thursday

September 29, 2022
11.15 a.m.

Diagnosis: This Thursday, local atmospheric factors such as evaporation and the entrance of humidity from maritime sectors, will cause isolated but intense downpours in the national territory, and again it will be in the center of the country and along the Pacific coast where precipitation will be concentrated during the afternoon and early evening.

Forecast: Rainfall amounts are expected in the Central Valley between 20mm and 40mm with maximum amounts of up to 75mm in the GAM and mountains south of the region.

In the Pacific slope, both in the Central Pacific and South Pacific coasts, amounts between 40mm and 60mm with maximums of up to 90mm are expected.

Meanwhile, in the Northern Zone, the rains will be scattered but intense in the plains. On the contrary, in the Caribbean, it will continue with scarce precipitations as it has been characteristic in the last days.

Warning: High levels of saturation in soils remain in the mountains south of the Central Valley; in addition to the Central and South Pacific coast, so they are highly vulnerable sectors. Caution is recommended for possible landslide or flooding incidents on Route 1 and Route 27.

Due to the above, the IMN recommends:


  • - Caution for sewer saturation and possible flash floods.
  • - Prevent thunderstorms and seek shelter in a safe place in case of strong gusts of wind near the storm clouds, due to the possible fall of tree branches, power lines, among others.
  • - Stay informed through social networks, Twitter: @IMNCR, Facebook: Instituto Meteorológico Nacional CR and the WEB Page:
