Weather Warning

Cold push # 18 in the northern Caribbean Sea accelerates the wind in the country

February 1st, 2020
6.00 p.m.

Diagnosis: Cold surge # 18 has entered the Caribbean Sea this afternoon and will be moving through this sector in the next two days. Due to this, the windy pattern in the country will increase over the course of this night, establishing windy conditions at least until Monday.

Due to the action of the wind, there will be a greater contribution of humidity from the maritime sector to the regions of the North Zone and the Caribbean, generating cloudy skies and scattered rains throughout the day. Part of these rains can reach the Central Valley in the form of drizzles and weak rains.

Forecast: The regions of the North Pacific and the Central Valley; and mountain passes will be gusts of wind between moderate to strong intensity. In Guanacaste, speeds between 60-70km / h and maximums of 85-95km / h are estimated near the mountain range. In the Central Valley, speeds between 40-50km / h and maximums of 60-70km / h are estimated.

The precipitations in the North Zone and the Caribbean will be dispersed throughout the day, with amounts accumulated between 15-30mm and maximums of 40mm for this Sunday; in addition, drizzles are expected in the mountainous sectors north and east of the Central Valley. On the Pacific Slope, no significant rainfall is expected for this day.

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.
