New Tropical Storm will enter the country today, say specialists

By the A.M. Costa Rica staff

The National Meteorological Institute warns about tropical storm No.38 of the green season, which is gradually approaching Costa Rica. It has a high probability of entering the national territory on Tuesday.

According to the latest report from the Institute, it expects the entry of a tropical storm into the country. Together with the proximity of the Inter-tropical Convergence Zone, it will generate unstable conditions reinforcing the electrical storms mainly the regions of the Pacific Coast, the northern zone and in the Central Valley.

Central Valley includes most of the regions in the provinces of San José, Cartago, Alajuela, and Heredia.

However, in the Caribbean Coast area, this new tropical storm is not expected to cause increased rainfall.

Specialists predict the storm will affect the country for at least 24 hours.

Since Sept 26, as A.M. Costa Rica reported,
the National Commission of Emergencies declared an alert for an increase in rains and the possible risk of floods, strong winds, and landslides.

According to the commission, the areas most affected by the rains have been the province of Guanacaste* and the province of Puntarenas*. Specifically in the area of the north and central Pacific coast. There is a yellow alert in that area.

A yellow alert was also declared in the province of San José* and the area of the South Pacific coast.

Green alert was declared on the rest of the country.

According to the Commission, it has been reporting damages to homes due to flooding, landslides overtaking roads, and debris being washed away by river currents in some villages.

Areas that have had the most emergency reports are in Guanacaste, in the communities of Santa Cruz, Pinilla, Nicoya, Nandayure, and Nosara.

In the community of Nosara, the road to the community of Ostional was closed, due to flooding.

According to the Meteorological Institute, the areas most affected by heavy downpours and thunderstorms are in the Nicoya Peninsula, Jaco Beach, and Parrita, with rainfall amounts of 150-240 mm.

In the Guanacaste area, downpours were recorded with levels between 20-60 mm. In San Jose, rains were recorded with levels between 30-60 mm.

In Cartago, rains between 40-80 mm were recorded. On the Caribbean coast, rains registered between 20-40 mm.

As A.M. Costa Rica has been reporting since August, the increase in rain is due to the presence of the ITCZ, known by sailors as the doldrums or the calms.

It is the area where the northeast and southeast trade winds converge. The ITCZ appears as a band of clouds, usually thunderstorms, that encircle the globe near the Equator.

Variations in the location of the ITCZ drastically affects the rainfall in many equatorial nations, resulting in the wet and dry seasons of the tropics rather than the cold and warm seasons of higher latitudes.

Longer-term changes in the ITCZ can result in severe droughts or flooding in nearby areas.

Due to the current conditions, people should be alert, especially in areas of high risk due to floods, landslides, or strong wind gusts.

Due to the alerts, specialists recommend:

 - Be alert in areas vulnerable to flooding due to sewer saturation, increased river flow, and landslides.

 - In case of a thunderstorm, take refuge in a safe place.

 - In case of strong wind gusts be alert to possible falling tree branches or electrical cables.

The authorities ask the public to call 911 to report any possible flooding, falling trees, or landslides.

The A.M. Costa Rica team asks readers to share this alert among their contacts.
