March 22, 2023.

09.50 a.m.

Discussion: The high values of atmospheric pressure over the Caribbean Basin are generating strong trade winds in our country. During the first hours of this day, very strong and constant gusts have been registered, reaching maximums of 105 km/h in La Cruz de Guanacaste, in other points of the North Pacific they oscillate between 45 km/h and 85 km/h; while in the Central Valley they are around 40-75 km/h, the highest speeds in the mountainous sectors of GAM. As a result of the drag of the wind, moisture penetrates at the surface level from the Caribbean Sea, causing cloudiness and precipitation in the North Zone and the province of Limón with amounts of less than 15 mm.

Forecast: During this Wednesday, very strong and recurring gusts will continue to be experienced in the Central Valley and lower parts of Guanacaste with estimated speeds between 50-85 km/h, while to the north of Guanacaste and the mountain ranges ranges between 80-110 km/h are anticipated.

It is possible for clouds to enter the province of Limón and the North Zone from the Caribbean Sea, causing scattered rains, mainly in the remainder of the morning and during the night, accumulated between 10-30 mm in periods of 12 hours. In addition, in the afternoon, due to local factors, isolated showers are expected in the South Pacific, amounts between 10-40 mm in periods of 6 hours.

Warning: Special attention due to strong gusts of wind in the North Pacific, Central Valley and the mountain ranges.
Due to the above, the IMN recommends:

• Prevention due to gusts of wind and their possible affectation of 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 kinds, as they can get out of control.
