Weather Warning

Showers with a thunderstorm in the Pacific, Central Valley, North Caribbean and North Zone regions during the night and early morning

October 01, 2022

Diagnosis: The Intertropical Convergence Zone is located over Costa Rica, which brings atmospheric instability and humidity to the national territory. This has favored the presence of localized downpours with electrical storms in some sectors of the Pacific, Central Valley, North Caribbean and North Zone. The most important accumulations in the last 3 hours are recorded in areas such as Naranjo 81.4mm (Central Valley), Puerto Jiménez 64.3mm (South Pacific), Canta Gallo 60.6mm (North Caribbean), Horquetas 42.4mm (North Zone), San Jorge 34.8 (Los Chiles, North Zone), Puente de Piedra 29.6mm (Grecia, Central Valley), Brasilia 29.6mm (Upala, North Zone), Muelle Herradura 21.8mm (Central Pacific). In the North Pacific, significant amounts have been recorded in a more localized manner (10-20 mm).

Forecast: During this morning, rainfall will continue with variable intensity in the North Zone, North Pacific, coastal sectors of the Central and South Pacific. The most intense activity is projected for the next 3 hours in the North Zone and North Pacific with accumulations of between 30 to 50mm. However, it is expected that in the course of the morning these systems will move towards the maritime regions, so a decrease in the intensity of the rains is expected and it is estimated that the accumulated ones will not exceed 30 mm in the following 3 hours.

Warning: High levels of soil saturation remain in the Central Valley, in addition to the Central and South Pacific coast, making them extremely vulnerable sectors. Caution is recommended in the event of possible incidents due to landslides or floods on Route 1 and Route 27.

Due to the above, the IMN recommends:

  • Caution for sewage saturation and possible flash floods.
  • Prevention before an electrical storm and seek shelter in a safe place in case of strong gusts of wind appearing or being perceived near storm clouds, due to the possible fall of tree branches, power lines, among others.
