Weather Warning

Rainy conditions this afternoon and evening

October 25, 2023
11.15 am

Diagnosis: The Intertropical Convergence Zone remains very active over Costa Rica. This situation has caused variable cloudiness in several regions of the national territory since early morning and variable rains have also been recorded in the Northern Caribbean this morning.

Forecast: This afternoon the variable behavior of precipitation will continue, also with heavy downpours located in part of the national territory. The North Pacific is the region that has the highest probability of significant precipitation accumulations this afternoon and evening, to a lesser extent the rest of the Pacific. Maximum accumulated accumulations of between 20-80 mm are estimated. Intermittent rains and fog banks in the rest of the country with accumulations between 10-60 mm.

Warning: Soil saturation with high percentages due to the rains of recent days continues in the North Zone (Sarapiquí), North Pacific (peninsula), mountains of the Central Pacific, South Pacific, Caribbean and west of the Central Valley, special attention is given .

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. • Stay informed through social networks, Twitter: @IMNCR, Facebook: National Meteorological Institute CR and the WEB Page: www.imn.ac.cr
