Weather Warning

Windy conditions on this Sunday

May 03, 2020
09.30 a.m.

Discussion: High atmospheric pressure values continue over the Caribbean Sea, consequently the trade winds remain with strong gusts in the country; with greater notoriety in the north and central part. So far, the highest speeds are 83 km/h north of Guanacaste, in the lower parts of the North Pacific and Central Valley they range from 50-65 km/h.

Forecast: Throughout this Sunday the windy pattern will be maintained between moderate and strong, maximum gusts are estimated in the range of 70-90 km/h in the mountainous areas and northern Guanacaste and between 50-70 km/h for the Central Valley and lower Guanacaste.

About rainfall; during the morning the rains will be scarce, being in the mountainous parts of the North Zone where they can manifest themselves, as well as in the Caribbean; with amounts less than 5 mm. In the afternoon and early evening, showers and showers with isolated thunderstorms are expected in the Central and South Pacific, accumulated between 25-50 mm.

Due to the above, the IMN recommends:

  • Take precautions for strong winds and their possible damage to roofs, electrical wiring, signs, trees; as well as in the mountainous parts of the country (national parks, volcanoes).
  • Caution for boats by rough sea in the North Pacific, Gulf of Nicoya, 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.
