The National Emergency Commission cautioned that rainfall might increase significantly during the rainy season, also known as the green season, which runs from April to November.

Authorities anticipate that the country will experience 15% more rain than last year, as well as more natural disturbances such as tropical waves and hurricanes.

As part of the El Niño-Southern Oscillation (ENSO) climatic trend, La Niña is believed to be responsible for the significant increase in rainfall.

La Niña is Spanish meaning "the girl." It has far-reaching impacts on the weather across the world, creating more tropical cyclones in the Atlantic Ocean basin owing to reduced wind shear and warmer sea surface temperatures while decreasing tropical cyclogenesis in the Pacific Ocean.

Rainfall is expected to rise mostly in the Pacific Coast (Guanacaste and Puntarenas provinces) and the Central Valley (San José Province).

As part of their preventative strategy, authorities have established 90 municipal warehouses stocked with food, first-aid supplies, mattresses, blankets, inflatable boats, and other equipment.

April corresponds with the slow start of the rainy season, according to the National Meteorological Institute. The rains already started on the Caribbean Coast. Then, wet weather is also affecting the southern Pacific Coast beginning this week.  

Rains are expected to start this weekend in the Central Pacific Coast. Toward the end of this month, rains will start on the North Pacific Coast and in the Central Valley.

Costa Rica's rainy season left more than 2,300 flood emergencies, experts added.

According to AccuWeather, a corporation that provides commercial weather forecasting services across the world, the 2024 hurricane season has the potential to produce around 25 named storms and a maximum of 12 hurricanes, including six significant hurricanes.

The National Hurricane Center (NHC) will begin releasing regular Tropical Weather Outlooks on May 15, 2024, approximately two weeks before the start of the season.
