Weather Warning

Heavy showers and thunderstorms this afternoon and evening

July 24, 2024
9:55 a.m.

Diagnosis: Humid atmospheric conditions will predominate due to the Intertropical Convergence Zone being active over the national territory. This will produce isolated showers in the north of the country this morning and will destabilize the Pacific in the afternoon and evening.

Forecast: In the afternoon and evening, on the Pacific side, showers with thunderstorms are expected along the coast, with amounts estimated between 50 mm and 70 mm with maximums of 100 mm, the areas with the greatest possibility of heavy showers in the Central and South Pacific, as well as in the Nicoya Peninsula/Gulf. The rains will extend into the night period. In the Northern Zone and Central Valley, the rains will be concentrated in the mountainous areas, with amounts between 15 mm and 50 mm. Part of these rains will reach the mountains of the Caribbean, with estimates between 10 mm and 30 mm.

Warning: Mountains in the Northern Zone and Northern Caribbean are prone to landslides due to high soil saturation and possible river overflows at the foot of the mountains. Also, on the Pacific side, be careful in both peninsulas due to high levels of saturation.

Due to the above, the IMN recommends: • Caution due to sewer saturation in places prone to this type of flooding. • Prevention in the event of an electrical storm and seeking shelter in a safe place in the event of strong gusts of wind occurring or perceived near the storm clouds, due to the possible fall of tree branches, power lines, among others. These gusts can reach 80 km/h in some isolated cases. • Stay informed through social networks, Twitter: @IMNCR, Facebook: Instituto Meteorológico Nacional CR and the WEB Page: www.imn.ac.cr
