Septiembre 21, 2023

09.55 a.m.

Diagnosis: Factors such as the moderate trade wind in the north of the country, a nearby and active Intertropical Convergence Zone, as well as warm temperatures for both slopes, will be the ingredients that will modulate the weather and give way to localized downpours with storms of strong intensity.

Forecast: For the afternoon, localized downpours with storms are forecast, but of strong intensity, both in the western and mountainous regions of the Caribbean and on the Pacific slope. Specifically, in localities in the west of the North Caribbean, South Caribbean, the mountains of Coto Brus and Zona de los Santos, the canton of Aguirre and Parrita, there will be occasional downpours with storms. In addition, to the east and west of the Central Valley there is a chance of showers with occasional storms. The estimated amounts will be between 20 - 40 mm with specific maximums between 60 - 80 mm.

The Northern Zone will experience occasional showers in the afternoon and at night, while in the North Pacific the probability of occasional downpours and a possible storm over the peninsula will remain. The estimated amounts will be between 20 - 40 mm with specific maximums of up to 50 mm.

Warning: Special attention to mountainous sectors of the North Zone, South Pacific (Coto Brus, Fila Brunqueña Oriental), as well as to mountainous sectors of the west and north, both the Central Valley and the North Caribbean. This is due to saturated soil conditions, which increases the probability of landslides.

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 between 80 to 100km/h in some isolated cases.
