Weather Warning

Strong windy pattern persist over the country

February 22, 2020
10.30 a.m.

Diagnosis: The influence of the cold surge #20 has been perceived in the country since yesterday Friday, and even today Saturday continues to generate strong winds in the Central Valley, the North Pacific and the Cordilleras. Since midnight the gusts have been strong with maximums of up to 104 km/h in La Cruz de Guanacaste, while in the lower parts of the North Pacific they range between 40-70 km/h and in the Central Valley between 30-75 km/h. As for the rains, these have been very scarce in the Caribbean and the North Zone as well as in the rest of the country.

Forecast: The trade winds pattern is estimated to continue between moderate and strong. For Saturday today, maximum speeds are estimated between 40-80 km/h in the Central Valley and the lower parts of the North Pacific, while in the mountains of these regions speeds are predicted between 70-100 km/h.

For the remainder of this Saturday and on Sunday, the rains will be extremely scarce, some of these being located on the summits of the Central Valley and the North Pacific. Rainfall is not expected in the rest of the country.

It is estimated that the cold push maintains its influence in the country until Sunday inclusive.

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.
