Weather Warning

Strong gusts of wind will remain during this Friday

January 18th 2019
09.00 a.m.

Diagnosis: The high pressure system positioned over the Gulf of Mexico that has affected the region has weakened a bit, which implies a decrease in atmospheric pressure values ??in Central America and the Caribbean Sea, however, moderate trade winds are maintained with occasional strong bursts in the country. The speeds this morning have reached 91.5 km/h in the Orosi Volcano, 88.9 km/h in La Cruz, 67.5 km/h in Liberia, 47.1 km/h in Irazu Volcano, 64.1 km/h in Alajuela and 42.6 km/h in Pavas.

Forecast: The windy conditions are expected to continue during this Friday, with maximum gusts between 60-85 km/h in the mountain ranges of Guanacaste, Tilarán, Central Volcanic Range and Talamanca sector; while, in the lower parts of the Central Valley, the Gulf of Nicoya and the Nicoya peninsula are estimated gusts between 40-70 km/h.

Few precipitations are anticipated due to the presence of a mass of dry air over the national territory and the Caribbean Sea. Most of the Pacific and Central Valley will be sunny. For the Caribbean slope, variable cloudiness is expected without precipitation.

This Sunday is expected a very strong increase in the trade winds and also rainy conditions in the Caribbean due to the influence of cold surge #14 which will be entering the Caribbean Sea from Sunday afternoon. This push is estimated to be generating gusts above 100 km/h in the mountainous sectors.

Due to the above, the IMN recommends:

  •     Extreme precautions for strong winds and 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 sharp sea and very strong waves in the North Pacific, Gulf of Nicoya, Central Pacific and the Caribbean Sea.
  •     Caution in air navigation due to turbulence over mountainous sectors.
  •     Avoid burning of all kinds since they can get out of control.
  •     Stay informed through social networks, Twitter: @IMNCR, Facebook: National Meteorological Institute and the WEB page: www.imn.ac.cr
