Diagnosis: This Tuesday the effects of the cold push #3 that last weekend was transiting the Caribbean Sea persist. The high pressure system that accompanies this push, increases the intensity of the trade winds in Central America and part of the Caribbean basin, dragging moisture into the region and that will generate rainfall in Costa Rica.

In the last 24 hours, amounts between 100 mm and 170 mm were recorded in the North Caribbean in the cantons of Pococí, Siquirres and Matina; between 80 mm and 90 mm in the canton of San Carlos and between 90 mm to 100 mm in the canton of Turrialba. According to reports from the National Emergency Commission, increased flow has been reported in the Siquirres, Pacuare and Reventazón rivers in the Northern Caribbean; as well as in the San Lorenzo, La Tigra and Florencia rivers in the Northern Zone.

Regarding wind, winds of up to 100 km/h have been registered near the Guanacaste Mountain Range and in the Central Valley up to 70 km/h in the higher parts of the hills.


Forecast: Rainfall is expected during the course of the day both in the Caribbean regions and in the Northern Zone, with estimated amounts between 30 mm and 60 mm near the mountains with maximums of up to 100mm; while, punctual values between 90mm and 100mm are expected near the coast and the border sector.
Part of the rains reach the mountains north of the Central Valley in the form of drizzle and light showers.
On the other hand, in the Central Pacific and South Pacific there will be scattered showers in the afternoon.

In addition, wind gusts of up to 100 km/h are expected in the North Pacific near the Guanacaste mountain range and 90 km/h in the hills and volcanoes of the Central Valley.
The influence of cold push #3 will extend until Wednesday, being today Tuesday and tomorrow Wednesday the rainiest days in both the Caribbean and Northern regions.
Warning: Both in the mountainous sectors of the Caribbean and the Northern Zone have reached 100% of its saturation capacity in the soils, therefore, they present high vulnerability to flooding in the coming hours in the cantons of Sarapiqui, San Carlos (particularly Aguas Zarcas), Pococí, Matina and Siquirres.

Due to the above, the IMN recommends:

• - Caution for sewer saturation in places prone to this type of flooding, as well as for increased flow in rivers and streams.
• - Caution for wind gusts and possible damage to roofs, electrical wiring, signs, trees, as well as in the mountainous parts of the country and Guanacaste (national parks, volcanoes).
• - Caution in air navigation due to the increase of turbulence, as well as in maritime navigation due to the increase of rough seas, especially in the North Pacific, Gulf of Nicoya and north of the Central Pacific.
• - Avoid fires of all types, as they may get out of control.
• - Stay informed through social networks, Twitter: @IMNCR, Facebook: Instituto Meteorológico Nacional CR and WEB Page: www.imn.ac.cr

Next report: Tuesday, December 3 at 6 p.m.
