Weather Warning (Update)

Rainy activity this Tuesday in the country

May 21, 2024
4:50 p.m.

Diagnosis: The passage of Tropical Wave #3 and the instability of the Intertropical Convergence Zone has presented downpours with storms towards the center and south of the national territory. So far there are accumulated maximums of: 75 mm in Neily-Coto 49, 66 mm in La Roxana-Pococí, 40 mm in the Brisas de Coto Brus, 30 mm in Santa Barbara and surrounding sectors of the north of the Central Valley.

Forecast: For the remainder of the afternoon, the presence of heavy localized rains and downpours accompanied by storms is forecast, especially in the Central and South Pacific, northwest of the North Pacific, mountainous sectors and in the west in the Northern Caribbean. The accumulated for these regions will be between 20 - 50 mm with maximums between 65 - 85 mm.

At night we expect variable rainy activity to still remain on the coasts and adjacent maritime sectors of the South Pacific and Central Pacific. The estimated accumulations for these regions will be between 10 – 40 mm with local maximums of 60 mm.

Warning: Attention in the Talamanca sector, General Valley, South Pacific border and the mountains of the Northern Caribbean, Northern Zone in the Sarapiquí sector, central sector of the Nicoya peninsula and Central Valley in general, this due to humid soils. Be attentive to the development of storm clouds which present their own and significant characteristics such as descending gusts, high precipitation intensity in short periods of time and electrical discharges.

Due to the above, the IMN recommends:

• Caution due to sewage saturation in places prone to this type of flooding.

• 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. These gusts can reach 80 km/h in some isolated cases.

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