Forecast: It is estimated that during the night and during the early hours of this Wednesday the cold push is affecting the national territory. The main feature will be the projection of intense gusts of wind; Maximum speeds between 80-110 km/h are expected in Central Valley and North Pacific. Windy conditions will also be perceived in the mountains of the Central and South Pacific.

In addition, light rains and drizzles are possible in the north and east of the Central Valley and the north of Guanacaste, accumulated less than 5 mm.

The cold surge is projected to move rapidly to the Atlantic Ocean; therefore, the greatest impact will be during this Wednesday and part of Thursday; however, the weather conditions will continue extremely windy over the country at least until next Sunday due to the strengthening of a high-pressure system in the Atlantic.

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.
