Tropical Depression May Bring Stormy Weather To Costa Rica

Costa Rica is expected to experience several more days of stormy weather over the week as a tropical depression develops in the Pacific Ocean, announced the National Meteorological Institute (IMN) on Wednesday.



Meteorologists said that although authorities recently issued an alert for parts of the country's Pacific region due to an anticipated reduction in rainfall during the rainy season, precipitation associated with tropical waves and hurricanes remains possible throughout the season.



Costa Rica has a tropical and subtropical climate with two primary seasons. The dry season, commonly known as summer, generally runs from December through May, while the rainy season extends from June through November and typically coincides with the Atlantic hurricane season.






According to meteorologists, the U.S. National Oceanic and Atmospheric Administration and the U.S. National Hurricane Center are monitoring conditions in the Eastern Pacific and have issued advisories regarding a developing weather system.


"An area of low pressure is forecast to form offshore of Central America and southern Mexico during the next couple of days," the National Hurricane Center said in a statement.


"The environmental conditions appear conducive for gradual development of this system thereafter, and a tropical depression could form late this weekend or early next week while it moves slowly northward."


U.S. weather experts said there is a 50% chance of the system developing into a tropical depression within the next seven days.


As of Wednesday, the weather system was located along the Pacific Coast from Guatemala to northern Costa Rica and is forecast to continue moving northwest toward Mexico during the next seven days, according to the National Hurricane Center.


Although the storm is not expected to make direct landfall in Costa Rica, IMN warned that it could still indirectly affect the country by bringing increased rainfall.


Costa Rican meteorologists expect stormy conditions to affect the country's Pacific Coast from Friday through Monday as the system moves towards Mexico's Pacific coastline.


Residual moisture associated with the system could continue generating showers through Tuesday, with weather conditions expected to gradually improve by Wednesday.


The IMN also warned that the Intertropical Convergence Zone, a low-pressure belt near the equator that helps fuel storm activity, is expected to enhance rainfall as it shifts across Costa Rica from the Pacific Ocean toward the Caribbean Sea.




The IMN forecast the following rainfall totals across the country:



  • Central Mountain Range: 50 to 80 millimeters, with the heaviest rainfall expected at higher elevations.



  • Pacific Coast, including Guanacaste Province and Puntarenas Province: 30 to 50 millimeters.



  • Central Valley, including San José, Alajuela, Heredia and Cartago: 30 to 50 millimeters.



  • Caribbean Coast, including Limón: 30 to 60 millimeters, with thunderstorms likely.







The CNE is maintaining a Green Alert, the agency's lowest warning level, for the Caribbean Coast, including Limón Province.



Under a Green Alert, local emergency committees are instructed to closely monitor conditions because of an elevated risk of flooding and other weather-related emergencies.


No rain-related alerts have been issued for the rest of the country.




The Ministry of Public Works and Transportation (MOPT) issued a precautionary advisory for Route 32, the main highway connecting San José and Limón. Authorities said overnight closures are possible because of heavy rain and the risk of landslides.



Drivers were advised to use alternate routes, including Route 10 through Turrialba canton (Cartago) and onward to Siquirres canton (Heredia), before reconnecting with Route 32 toward Limón. MOPT said it will post traffic updates through its official social media channels.

Authorities urged residents to take several precautions during the storm, including:

  • Avoid rivers and lakes during periods of heavy rain.


  • Monitoring mountainous areas for landslides and falling debris.


  • Residents in flood-prone communities are urged to review evacuation plans.


  • Drivers were warned to watch for flooding, slippery roads and reduced visibility.


  • Remain alert for strong winds that could bring down trees or power lines.


  • Stay indoors during thunderstorms and avoid using electronic devices during lightning activity.


  • Call 911 to report flooding, landslides or fallen trees.




The IMN is Costa Rica’s government agency responsible for issuing weather forecasts, hazardous weather warnings and related public safety information.



CNE works in partnership with communities and emergency responders to strengthen the nation’s preparedness, response, and recovery from natural hazards.



MOPT is the government agency responsible for managing the country’s roads, ports, and airports, as well as overseeing public transportation policy.



A.M. Costa Rica encouraged readers to share the weather advisory with their networks
