Weather Warning
Windy conditions persist on this Wednesday
February 19, 2020
07.40 a.m.
Discussion: A large high-pressure system positioned in the Atlantic Ocean maintains high levels of atmospheric pressure on the Caribbean Sea, in turn causing a very strong windy pattern in the country. During the morning the gusts have been intense with maximums of 106 km/h in La Cruz de Guanacaste, in the lower parts of the province they range between 50-85 km/h; meanwhile in the Central Valley speeds range between 40-73 km/h.
Forecast: Windy conditions will prevail very strong on this day and on a recurring basis. Maximum speeds are estimated between 50-85 km/h in the Central Valley and the lower parts of the North Pacific, while speeds between 90-115 km/h are expected in the mountains of these regions.
Regarding rainfall, weak and isolated rains are expected in the Caribbean and the North Zone, especially during the morning and night, with accumulated between 5-20 mm. Rainfall is not expected in the rest of the country.
Due to the above, the IMN recommends:
- Extreme precautions due to strong winds and their possible impact on roofs, electrical wiring, signs, trees; as well as in the mountainous parts of the country (national parks, volcanoes).
- Caution for boats by choppy sea and very strong waves in the North Pacific, Gulf of Nicoya, Central Pacific and the Caribbean Sea, as well as air navigation due to turbulence over the mountainous sectors.
- Avoid burning of all kinds as they can get out of control.
