Alert in Costa Rica: CNE Declares Yellow and Green Alerts for Cold Front and Tropical Wave

Table of Contents

Authorities forecast strong wind gusts in the Central Valley and North Pacific, along with heavy rainfall in the Caribbean and Northern Zone this Tuesday and Wednesday.

The National Emergency Commission (CNE) has raised alert levels for several regions of the country due to adverse weather conditions expected over the next 48 hours. The situation is caused by the interaction of two phenomena: Cold Front #3 and Tropical Wave #44.

According to a report from the National Meteorological Institute (IMN), while the cold front will not directly enter the country, its influence is generating a significant increase in the speed of the trade winds. This phenomenon is combining with the moisture from the tropical wave, creating a scenario of high precipitation and strong winds.

Alert Details by Region

Authorities have defined the following alert status based on the projected risk level:

YELLOW ALERT

(Preparation and monitoring for moderate/high risk)

  • Caribbean Region (North and South): The most significant impact in terms of precipitation is anticipated here. Heavy downpours and intermittent rain are expected, with a high risk of flooding in vulnerable areas and potential soil saturation.
  • Northern Zone (including Sarapiquí): Like the Caribbean, this region is expected to receive the largest amount of rainfall, increasing the risk of swollen rivers and landslides in mountainous areas.

GREEN ALERT

(Information and prevention for low/moderate risk)

  • Central Valley: The primary phenomenon will be wind. The IMN forecasts strong gusts that could reach speeds between 80 and 90 km/h (50-56 mph). Drizzle and a marked decrease in temperatures are also expected.
  • North Pacific (Guanacaste): Windy conditions similar to the Central Valley will be recorded, especially in the mountain ranges and lowlands.

Situation Analysis

The IMN clarifies that the main event is not the cold itself, but the “combo” of wind and rain. The Cold Front is acting as an “accelerator” for the trade winds, while the Tropical Wave provides the “fuel” (moisture) for the heavy rains on the Caribbean slope.

For the Central and South Pacific regions, a lesser impact is expected, although isolated showers are possible, mainly in mountainous areas.

Official CNE Recommendations

Given this outlook, the CNE has issued a series of prevention guidelines for the public:

  1. Caution When Driving: Extreme caution is requested on roads due to low visibility, potential landslides, falling branches, and slippery pavement.
  2. Wind Risk: In the Central Valley and Guanacaste, secure roofs, windows, and loose objects (such as planters or garden furniture) that could be dislodged by the gusts.
  3. Avoid Risk Zones: In the Caribbean and Northern Zone, the public should refrain from crossing swollen rivers or streams.
  4. Stay Informed: The public is urged to consume information only from official sources (CNE, IMN) and to avoid spreading rumors.
  5. Emergencies: Report any hazardous situation or emergency immediately to the 9-1-1 system.

Authorities stated they will maintain constant monitoring of the evolution of both phenomena throughout the day.
