March 08, 2019
07.15 a.m.

Discussion: Atmospheric pressure remains high in the Caribbean Sea and Central America, causing the persistence of accelerated winds over the country, especially in the Central Valley, the North Pacific and the mountain ranges. In the first hours of this day there have been gusts of up to 95 km/h in La Cruz de Guanacaste, in the rest of said province they hover between 60-85 km/h, while in the Metropolitan Area the maxima range between 40-70 km/h.

Forecast: The windy pattern will continue very strong on this Friday over the national territory; maximum gusts are estimated between 70-100 km/h in the north of Guanacaste, as well as in the mountain ranges of Guanacaste, Tilarán, Central Volcanic Cordillera, Talamanca sector; On the other hand, in the lower parts of the Central Valley, the Nicoya Gulf and the Nicoya Peninsula, gusts are estimated between 50-80 km/h.

In addition, a very isolated behavior of rainfall is expected, to manifest itself in the mountainous sectors in the form of weak rain and drizzle with amounts less than 10 mm in 12-24 hours.
The effect of the wind generates cool temperatures in the north and east of the Central Valley (San José, Cartago, Heredia mountains) with peaks between 19-24 ° C, in the rest of the country no significant changes in temperature are expected.

Due to the above, the IMN recommends:

  • Extreme precautions for intense winds and their possible impact on roofs, electrical wiring, signs, trees; as well as in the mountainous parts of the country (national parks, volcanoes).
  • Also, take precautions for the boats by sharp sea and strong waves in the North Pacific and the Gulf of Nicoya, as well as the aerial navigation by turbulence on the mountainous sectors.
  • Extreme caution -at the aeronautical level- due to strong turbulence over the mountainous sectors in Guanacaste and the Central Valley
  • Avoid burning of all kinds as they can get out of control.
