Weather Warning

Affectation cold front # 4

February 27, 2020
05.00 p.m.

Discussion: The cold front # 4 has entered the north of Central America, associated with its passage has raised atmospheric pressure levels in the region and at the same time causes the gradual increase in wind gusts in the country, especially in the Central Valley and North Pacific with maximum speeds so far between 50-70 km/h.

Forecast: It is expected that this cold front will continue advancing towards the south of the region, reaching the north of Costa Rica on Thursday night towards Friday morning, extending its influence during Friday and the weekend. Due to the above, the gradual intensification of the windy pattern is expected, maximum gusts are estimated between 60-90 km/h in the Central Valley and North Pacific, and may be higher (around 120 km/h) in northern Guanacaste.

In addition, the Caribbean, the North Zone, as well as the east/north sector of the GAM will experience an increase in cloud cover and rainfall, intermittent rains are anticipated on Friday and weekend in Limon and North Zone, as well as drizzles in the Central Valley and mountains of the North Pacific. Sunday is expected as the one with the highest rainfall activity especially for the Caribbean side.

On the other hand, a significant decrease in daytime temperatures (with greater accent on Sunday) is expected mainly in the Central Valley due to the proximity of the cold air mass associated to the front over the north of the country.

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 in areas vulnerable to flooding due to sewer saturation, increased flow in rivers and streams, and in areas prone to landslides.
  • 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.
  • Stay informed through social networks, Twitter: @IMNCR, Facebook: National Meteorological Institute and the Website: www.imn.ac.cr
