January 17, 2020
10:00 am

Diagnosis: a high pressure system has favored an increase in trade winds in the national territory. The most intense gusts are perceived today are located in Guanacaste with maximums of 100 km / h and 85 km / h in the mountainous sectors of the country.


Forecast: during the morning and afternoon conditions of moderate to strong winds will be maintained with maximums of up to 110 km/h in Guanacaste, on the other hand, moderate winds with maximum gusts of 80 km/h will be presented in the Central Valley and mountains of the central mountain range. Intermittent rains are expected in the Caribbean and North Zone, particularly in the highlands, with accumulated between 5-40 mm this Friday. In the rest of the country rainfall is not expected during this day.


At night, an increase in trade winds is expected, which will be increasing gradually throughout the country, reaching gusts of up to 120 km / h.
It is expected that during the weekend the affectation of said system will be maintained, generating strong trade winds, cloudy and rainy conditions in the Caribbean and North Zone.

 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.
