Zona de Convergencia Intertropical sobre Costa Rica y disminución de la influencia indirecta de Huracán Beryl

4 de julio de 2024

10.00 a.m.

Diagnosis: Hurricane Beryl continues its passage through the Caribbean Sea and this morning is west of Grand Cayman Island, heading towards the Yucatan Peninsula in Mexico, with maximum sustained winds of 195 km/h, being a category 3 hurricane.

Due to Beryl's position, it generates an indirect influence in Costa Rica by locating the Intertropical Convergence Zone over the country, which is increasing the atmospheric instability in the country this Thursday; however, as Beryl approaches Mexico, its influence will diminish.

Forecast: For this afternoon, showers with thunderstorms are expected along the mountain ranges of the national territory, mainly in the Guanacaste Mountain Range and the Central Volcanic Range; with estimated amounts between 50 mm and 75 mm with punctual maximums higher than 100 mm in the mountains of the Northern Zone and the Northern Caribbean. Meanwhile, in the lower parts of the Northern Zone, Northern Pacific and Central Valley, amounts between 30 mm and 60 mm are expected.

In addition, rains are expected in the South Pacific extending to the Central Pacific coast from late afternoon and early evening, with estimated amounts between 40 mm and 60 mm with maximum amounts between 80 mm and 90 mm.

Warning: Rainfall in urban areas may generate flash floods and sewer saturation due to high saturation in the GAM, North Pacific and North Zone plains. Also, be alert for landslides in the mountains of the Northern Zone and the Caribbean.

Due to the above, the IMN recommends:

- Caution for sewer saturation in places prone to this type of flooding.
- Prevention before thunderstorms and seek shelter in a safe place in case of strong gusts of wind near the storm clouds, due to the possible fall of tree branches, power lines, among others. These gusts can reach 80 km/h in some isolated cases.
