Weather Warning

Windy conditions this Friday and weekend

Discussion: The gradual increase in atmospheric pressure over the Caribbean Basin has caused the increase in trade winds in Costa Rica. The Central Valley, the North Pacific and the mountain ranges are the regions where constant gusts are being experienced, with maximum speeds so far in some of the IMN stations: 84 km/h in Carrillo, Orosi Volcano 82 km/h, Bagaces 73 km/h, 65 km/h in Juan Santamaría Airport, 60 km/h in Barva de Heredia, 54 km/h in Santa Ana, 94 km/h in Chirripó.

Forecast: For this day and during the weekend, trade winds are expected with moderate to strong intensities, estimated ranges close to 100 km/h in the north of Guanacaste and the mountain ranges, while in the Central Valley and the lower parts of the Pacific North estimated between 40-65 km/h.

In addition, a mass of dry air is positioned over the region, favoring mostly stable conditions and little precipitation in the country. The possibility of rain will be limited to the South Pacific in the afternoon, which will be short-term rains.

Warning: Special attention due to strong gusts in the Central Valley and the North Pacific.

Due to the above, the IMN recommends:

  • Prevention of wind gusts and their possible impact on roofs, electrical wiring, signs, trees; as well as in the mountainous parts of the country and Guanacaste (national parks, volcanoes).
  • Caution in air navigation due to increased turbulence, as well as in maritime navigation due to increased rough seas, especially in the North Pacific, Gulf of Nicoya and northern Central Pacific.
  • Avoid burning of all types, as they can get out of control.
  • Stay informed through social networks, Twitter: @IMNCR, Facebook: National Meteorological Institute CR and the WEB Page: www.imn.ac.cr
