Weather Warning

Downpours this day in the country

May 15, 2024
9.20 am

Diagnosis: The Intertropical Convergence Zone remains close to the country and very active, which is generating humid and unstable conditions since the morning in coastal sectors of the North Pacific. In addition, local factors such as morning warming and the contribution of humid flow from the Pacific Ocean to land contribute to instability in the country in the next three days.

Forecast: On the afternoon of this Wednesday, heavy rains and downpours with electrical storms are estimated in regions of the Pacific and Northern Zone, amounts between 40-80 mm, while in the Central Valley, mountains of the Caribbean and the Northern Zone, reactivation of the storms is anticipated. Precipitation especially in the second part of the afternoon, amounts between 30-60 mm. At night, rains and downpours with storms are expected located between the coastal Pacific only at the beginning of the period with amounts between 10-40 mm.

Warning: Be careful in sectors of the Pacific in general due to humid soils both in low areas and especially in mountainous areas. Special attention in urban areas of the Central Valley due to possible flooding due to sewage saturation. In addition, heavy rains in the Northern Zone can generate rapid growth of streams and rivers. 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 Gabriela Chinchilla R.
