Weather Warning

Friday afternoon with variable rains in the country

May 17, 2024
09:10 a.m.

Diagnosis: The Intertropical Convergence Zone maintains instability and humidity over central and southern Central America, coupled with local factors such as breezes and morning warming, will be favoring afternoon rain over the country.

Forecast: During the afternoon today, the presence of downpours with storms is forecast over the mountains of the South Pacific, towards the center and west of the Central Valley, as well as the Central Pacific and North Pacific. The accumulations for these regions will be between 30 - 50 mm with maximums between 60 - 80 mm, with the sectors in the center and northwest of the country being where the highest accumulations are recorded.

The Northern Zone and Caribbean regions will present scattered showers and downpours accompanied by electrical storms, being over the mountains for the Caribbean sectors. The estimated accumulations for these regions will be between 15 – 40 mm with local maximums of 60 mm.

Warning: Be careful in mountainous sectors of the General Valley, those of the South Pacific and the mountains of the Northern Caribbean, 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
