Regarding precipitation, the pattern of drizzle will continue in the mountains of the Caribbean and the Northern Zone this afternoon, although we could perceive weak rains during the night, with accumulations of between 10-20 mm in periods of 6-12 hours. . In addition, the possibility of drizzle is estimated in mountainous sectors to the east and north of the Central Valley. No precipitation is expected for the rest of the country.
The front and the cold mass of this EF will not reach our country.
Warning: Special attention due to very strong gusts of wind in the North Pacific and the Central Valley.
Due to the above, the IMN recommends:
• Prevention of wind gusts and their possible impact on 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 increased turbulence, as well as in maritime navigation due to increased rough seas, especially in the North Pacific, Gulf of Nicoya and northern Central Pacific.
• Avoid burning of all types, as they can get out of control.
