11:15 p.m.

Diagnosis: The Intertropical Convergence Zone remains over the Central American Isthmus, after the indirect influence of Hurricane Rafael has left, bringing instability and humidity to the country.

As of 10:00 p.m., the most important accumulations of the last 6 hours by region are: North Zone (La Fortuna 105 mm, Las Delicias, Pital - San Carlos 86.4 mm, La Virgen de Sarapiquí 54.6 mm and Río Tirimbina, Sarapiquí 54.4 mm), North Pacific (San Mateo, Alajuela 74.2 mm, Aranjuez, Pitahaya - Puntarenas 52.6 mm, Carrillo - Guanacaste 50.6 mm), Central Pacific (Asada San Gabriel, Desamparados 66.4 mm, Muelle Herradura 66.2 mm and Marina Pez Vela 59.2 mm), South Pacific (Ciudad Neily 98 mm, Las Esfera - Osa 60 mm and Fundación Neotrópica, Osa 57.6 mm), Central Valley (Santa Lucía, Heredia 87.6 mm, Aranjuez 73.4 mm, Cerro Burio 68.4 mm, Iztarú 68.4 mm and Recope, Ochomogo 60.9 mm), North Caribbean (Horquetas Hydroelectric 109.4 mm and Rain Forest, Braulio Carrillo 52.6 mm), South Caribbean (Guayabo – Turrialba 62.4 mm and Juan Viñas 52.4mm).

Forecast: For the second part of the night period, a decrease in the intensity and distribution of precipitation is expected. For the Pacific Slope, North Zone and Caribbean, localized rains and showers are expected, with estimated accumulations of 20 -40 mm, in periods of 6 - 12 hours.

For the Central Valley, scattered rains are possible, with accumulations between 5-15 mm in periods of 6 - 12 hours.

According to the latest analyses, instability and humidity will continue in the region, not only due to the activation of the Intertropical Convergence Zone, but also due to the passage of tropical wave #45 this Friday and the increase in instability of the upper atmosphere over the Caribbean Sea. Therefore, the probability of rain on the Pacific side is high and increasing, especially in regions that are already vulnerable due to the rains of the last few days.

Warning: Soil saturation, with extremely high percentages, continues in both Peninsulas, the entire North Pacific, mountains of the South Pacific, North Zone, Central Pacific and Central Valley, so it is recommended to take extreme measures since they are highly vulnerable to incidents.

Due to the above, the IMN recommends:

• Caution due to sewer saturation in places prone to this type of flooding.
• Prevention against thunderstorms and seek shelter in a safe place if strong gusts of wind occur or are perceived near 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.
