Authorities monitor the arrival of Tropical Wave No. 5
The arrival of Tropical Wave No. 5 has prompted meteorological authorities to closely monitor weather conditions due to the possibility of increased rainfall and thunderstorms in several regions of the country over the coming days.
According to reports from the National Meteorological Institute, the phenomenon could significantly intensify precipitation, particularly in the Caribbean region, Northern Zone, Pacific region, and Central Valley, during a period marked by the consolidation of the rainy season.
Atmospheric conditions could favor intense rainfall
IMN specialists explain that the combination of the tropical wave, moisture from the Caribbean Sea, and the influence of the Intertropical Convergence Zone (ITCZ) could generate heavy downpours accompanied by electrical storms in various parts of the country.
In addition, soils in several communities are already highly saturated due to rainfall recorded during recent weeks, increasing the risk of flooding, overflowing rivers, and landslides.
Rainy season enters a more active phase
At this time of year, tropical waves are common phenomena across Central America and often contribute to increased rainfall in Costa Rica.
Meteorologists indicate that June and the following months typically bring wetter weather patterns, especially in the Pacific and Caribbean regions, where rainfall tends to intensify during afternoons and evenings.
Preventive recommendations for the population
In light of the potential increase in rainfall, authorities recommend that residents stay informed through official channels and take preventive measures, especially in vulnerable areas.
Main recommendations include:
• Consulting official updates from the IMN and the National Emergency Commission.
• Avoiding crossing swollen rivers or flooded streets.
• Checking roofs, drainage systems, and gutters to prevent water accumulation.
• Exercising caution on roads prone to landslides or falling trees.
Continuous monitoring of tropical systems
Meteorological institutions continue monitoring atmospheric conditions across the Caribbean and Central America to evaluate the evolution of the tropical wave and potential additional impacts.
Constant monitoring allows authorities to issue early warnings and coordinate preventive actions in communities most exposed to hydrometeorological events.
