Diagnosis: The presence of weak trade winds, high temperatures and high humidity contents towards the south of Central America will be accompanied by instability due to the proximity of the Convergence Zone. The above will favor periods of afternoon and night rain this Saturday.

Forecast: During the afternoon period, the presence of scattered showers accompanied by an electrical storm is forecast in the mountainous parts of the South Pacific, which will move and develop later in low areas near the coasts, this for the end of the afternoon and early hours. of the night. The amounts accumulated in 12 hours will be between 25 - 50 mm with specific maximums of 75 mm. In the case of the Central Pacific, occasional showers and downpours with a short-duration storm are projected. The amounts will be between 15 - 50 mm.

For the surroundings of the Gulf of Nicoya, there will be showers and downpours accompanied by isolated storms. The accumulations will be between 10 - 30 mm with specific maximums of up to 60 mm.

The Central Valley will present showers to the north and west, with isolated rain to the east. The aculates will be between 10 - 45 mm.

Warning: Be careful in sectors of the South Pacific where rains have been recurrent in the afternoons, with the presence of humid soils both in low areas and especially in mountainous areas.

Due to the above, the IMN recommends:

• Caution due to sewage saturation in places prone to this type of flooding.

• Prevention against electrical storms and seeking shelter in a safe place in case strong gusts of wind occur or are perceived near storm clouds, due to the possible fall of tree branches, power lines, among others. These gusts can reach 80 km/h in some isolated cases.

Weather Warning

Windy conditions this Friday and weekend

Discussion: The gradual increase in atmospheric pressure over the Caribbean Basin has caused the increase in trade winds in Costa Rica. The Central Valley, the North Pacific and the mountain ranges are the regions where constant gusts are being experienced, with maximum speeds so far in some of the IMN stations: 84 km/h in Carrillo, Orosi Volcano 82 km/h, Bagaces 73 km/h, 65 km/h in Juan Santamaría Airport, 60 km/h in Barva de Heredia, 54 km/h in Santa Ana, 94 km/h in Chirripó.

Forecast: For this day and during the weekend, trade winds are expected with moderate to strong intensities, estimated ranges close to 100 km/h in the north of Guanacaste and the mountain ranges, while in the Central Valley and the lower parts of the Pacific North estimated between 40-65 km/h.

In addition, a mass of dry air is positioned over the region, favoring mostly stable conditions and little precipitation in the country. The possibility of rain will be limited to the South Pacific in the afternoon, which will be short-term rains.

Warning: Special attention due to strong gusts in the Central Valley and the North Pacific.

Due to the above, the IMN recommends:

• Prevention of wind gusts and their possible impact on 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 types, as they can get out of control.
