January 20th 2019

Diagnosis: The cold surge # 14 is located in the north of Central America / Canal de Yucatán and continues to go into the Caribbean Sea. At this time its effects are perceived in Guatemala / Belize; while in Costa Rica they will be perceived as the push moves to the south of Central America during the course of the day.

Forecast: The most recent analyzes are persistent in a strong increase in wind intensity over the country this Sunday. Strong gusts of wind are expected during the night of Sunday and early Monday morning exceeding 100 km / h in places near the Cordillera de Guanacaste and Tilarán; in addition, they exceed 80km / h in the Central Volcanic Mountain Range. While, in low areas of Guanacaste, the peninsula and GOLFO DE NICOYA, the North Zone, lower parts of the Central Valley, Talamanca sector and the North Caribbean are expected to record gusts between 50-70 km / h.

In the regions of the Caribbean and the North Zone scattered rains and between weak and moderate intensity are expected towards the end of the afternoon and during the course of this night and at least on Tuesday. Maximum accumulated amounts between 25-35 mm and maximum accumulated of 50-70 mm are estimated in periods of 24 hours.

It is expected a decrease in the maximum temperatures for the beginning of the week in the central and northern sector of our territory, decreasing daytime temperatures (with respect to those that have been presented this week) on average of 2 ° C in the Central Valley, Guanacaste, North 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 HEAVY WINDS AND THEIR POSSIBLE AFFECTION IN CEILINGS, ELECTRICAL WIRING, HEADS, TREES; as well as in the mountainous parts of the country (national parks, volcanoes).
• Extend also the CAUTION FOR VESSELS BY SEAWELLING AND VERY STRONG SURFING IN THE NORTHERN PACIFIC, NICOYA GULF, CENTRAL PACIFIC AND THE CARIBBEAN SEA, as well as aerial navigation by turbulence on the mountainous sectors.
• AVOID BREEDS OF ALL TYPES since they can get out of control.
