Weather Warning

Windy conditions and intermittent rains in the Caribbean will persist throughout the day

March 18, 2019
08.25 a.m.

Diagnosis: In the last hours the rainy conditions in the Caribbean have been maintained as a result of the affectation of a high pressure system. Maximum gusts have been recorded near 90 km / h in Guanacaste and in the Central Valley they oscillate between 45-65 km / h. The amounts of rain in 24 hours have been between 50-75 mm and up to 150 mm in 48 hours.

Forecast: The windy pattern will be maintained all day with a gradual decrease; maximum gusts are estimated between 70-100 km / h in Guanacaste, as well as in the mountains of Guanacaste, Central Volcanic Cordillera, Talamanca sector; On the other hand, in the lower parts of the Central Valley, the Gulf of Nicoya and the Nicoya Peninsula, gusts are estimated between 50-80 km / h.

Rains of variable intensity are expected throughout the day in the North and Caribbean Zone, with accumulated between 30-50 mm in periods of 12 hours. In addition, drizzle and weak rains are possible in the north and east of the Central Valley and north of Guanacaste with amounts less than 10mm in 12 hours.

The effect of the wind generates cool temperatures in the north and east of the Central Valley (San José, Cartago, Heredia mountains) which will be maintained throughout the day.

Due to the above, the IMN recommends:

    Caution for 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).
    Prevention for boats by sharp sea and strong waves in the North Pacific and Gulf of Nicoya, as well as air navigation due to turbulence in the mountainous sectors.
    Avoid burning of all kinds as they can get out of control.
