Afternoon of rain and downpours in various parts of the country
june 5, 2020
10:40 am
Diagnosis: Unstable conditions are present in the atmosphere over the region. The high values ??of temperature and humidity registered on the national territory this morning, generate a favorable panorama for the occurrence of rain and downpours for this afternoon and night in various areas of the country.
Forecast: For this afternoon and early evening, rains and showers are anticipated for the Pacific slope, the Central Valley (especially in the northern and western parts) and the Northern Zone. The highest probability of intense precipitation is projected for the mountainous areas and their surroundings.
In the Caribbean regions isolated rains with possible storms are expected punctually for the mountainous areas, while for the coastal parts no significant rainfall is expected. Warning: The rains of the last days keep humidity levels in the soils quite high in most of the national territory, particular attention for the Guanacaste zone, the Central Pacific, the North Zone, the mountainous parts of the South Zone and the North Caribbean by probability of incidents such as landslides, flash floods, water heads, etc.
Due to the above, the IMN recommends:
- • Caution in areas vulnerable to flooding due to sewer saturation.
- • Take refuge in a safe place in case of hearing an electrical storm or perceiving strong gusts of wind near the storm clouds, as well as precaution for possible fall of tree branches, power lines, among others.
- • Stay informed through social networks, Twitter: @IMNCR, Facebook: Instituto Meteorológico Nacional CR and the WEB Page: www.imn.ac.cr
