Rainy weather pattern persists in Costa Rica this Tuesday

November 12, 2024

10:00 a.m.

Diagnosis: This Tuesday, rains continue throughout the national territory, as the Intertropical Convergence Zone persists over Costa Rica providing constant humidity and generating weak rains in the country.

In the last hours, amounts between 5 mm and 15 mm have been registered along the Pacific regions and in the Central Valley, with a maximum value of 36 mm in the canton of Parrita.

Forecast: Rainfall will be continuous and of variable intensity throughout the national territory, with short periods of showers on the Pacific coast and plains of both the Northern Zone and the Caribbean. In the mountainous sectors and in the Central Valley, rainfall will be weak, but with moderate rains of short duration and temporary fog banks.

The estimated accumulations by region in a period of 6 to 12 hours are detailed below:

- North Pacific (particularly Nicoya Peninsula): ranges between 50 mm and 90 mm, with maximums between 100 mm and 150 mm near the coast.
- Central Pacific: ranges between 50 mm and 75 mm, with maxima between 100 mm and 120 mm near the mountains.
- South Pacific (special attention in mountains, on the coast and around Golfo Dulce): ranges between 40 mm and 80 mm on the coast, with maxima between 100 mm and 150 mm in the mountains.
- Central Valley (special attention in mountains): ranges between 10 mm and 25 mm, with maximums between 30 mm and 40 mm, mainly in the western sector of the region.
- Northern and Southern Caribbean (special attention in mountains, west and border area): ranges between 10 mm and 30 mm, with maximums between 30 mm and 60 mm.
- Northern Zone (special attention in the mountains and border areas): ranges between 30 mm and 45 mm, with maximums between 60 mm and 90 mm.
It should be noted that higher amounts are not ruled out locally in each respective region.

⚠ Attention: The rainy pattern will extend throughout the week. The IMN keeps tracking tropical wave #46 which has a high potential to evolve into a tropical cyclone over the Caribbean Sea in the next 7 days. We will be updating the information periodically.

Warning: High soil saturation is maintained in most of the country, with saturation levels between 85% and 100%. Therefore, there is a high probability of flooding in places vulnerable to them, mainly in the Pacific regions, and landslides in the mountains of the Central Valley, Cordillera de Tilarán and the Central Pacific.
 
Due to the above, the IMN recommends:

- Attention to the overflowing of streams and rivers with high flows.
- Be alert in places prone to landslides.
- Prevention before thunderstorms and seek shelter in a safe place in case of strong gusts of wind near the 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.
