Strong winds due to the effect of cold surget #14 this Sunday

January 19th 2019
8.30 a.m.

Diagnosis: This Sunday is expected a very strong increase in the trade winds and also rainy conditions in the Caribbean due to the influence of cold surge # 14 which will be entering the Caribbean Sea from Sunday morning. At this time, the push is on the Gulf of Mexico and will move south thru this Saturday.

Forecast: For this Sunday, will gradually increase the intensity of the wind over the country, as the cold surge is entering the Caribbean Sea. Strong gusts of wind are expected during the Sunday night and early Monday morning exceeding 100 km / h in the mountainous sectors of the Cordillera de Guanacaste and Tilarán; in addition, they exceed 90km/h in the Central Volcanic Mountain Range. While, in low areas of Guanacaste, the peninsula and Gulf of Nicoya, the North Zone, lower parts of the Central Valley, Talamanca sector and the North Caribbean are expected to record gusts between 60-80 km / h.

There will be a change in weather conditions in the regions of the North Zone and the Caribbean with respect to the last days, and rain is expected from Sunday night and at least until Tuesday morning. Maximum accumulated amounts between 50-70 mm are estimated in periods of 24 hours.

A decrease of the temperatures in the central and northern sector of our territory is foreseen for the days Sunday and Monday, diminishing the daytime temperatures (with regard to which they have appeared this week) in average of 2 ° C in the Central Valley, Guanacaste, North Zone and North Caribbean. In this way, it is anticipated that on both days the maximum temperature in the capital will not exceed 19 ° -20 ° C, lower values ??for areas such as Cartago and upper parts of Heredia.

Due to the above, the IMN recommends:

• Extreme precautions for intense winds and their possible impact on roofs, electrical wiring, signs, trees; as well as in the mountainous parts of the country (national parks, volcanoes).
• Also, take extreme precautions for boats by sharp seas and very strong waves in the North Pacific, the Gulf of Nicoya, the Central Pacific and the Caribbean Sea, as well as aerial navigation due to turbulence in the mountainous sectors.
• Avoid burning of all kinds since they can get out of control.
