Weather Warning

Variable rains in the Carribbean slope of the Country

March 25, 2025
5:40 p.m.

Diagnosis: The increase in moisture content throughout the beginning of this week in southern Central America continues, with steady cloud cover continuing into Tuesday in parts of the Caribbean and the Northern Zone. This translates into variable rainfall with accumulated rainfall since this morning ranging from 15 to 30 mm, with highs of 51 mm in parts of the Virgen de Sarapiquí (Northeastern Zone). Meanwhile, in the Central and South Pacific, very localized downpours are developing, with point accumulations of 30 to 45 mm in Osa, Neily, and Pérez Zeledón. Locally, up to 70 mm in Coto Brus.

Forecast: Scattered rain and showers are forecast in parts of the Caribbean and parts of the Northern Zone during the late afternoon and evening hours, with 12-hour accumulations of 15 to 25 mm, with local highs of up to 60 mm. In the Pacific regions, rainfall is gradually decreasing in intensity, with accumulated rainfall of less than 30 mm over the next 6 hours.

Due to the above, the IMN recommends:

• Caution due to sewer saturation in areas prone to this type of flooding, as well as increased flow in rivers and streams.

• Prepare for thunderstorms and seek shelter in a safe place if strong wind gusts occur or are felt near storm clouds, due to the possible fall of tree branches, power lines, among other things. These gusts can reach 80 km/h in some isolated cases.

• Stay informed through social media: Twitter: @IMNCR, Facebook: Instituto Meteorológico Nacional CR, and the website www.imn.ac.cr
