Weather Warning

Strong winds will persist this Thursday

January 09, 2020
09.40 a.m.

Discussion: After the transit of the cold surge # 15 through the north of the Caribbean Sea, intense gusts of wind continue to be registered on the country, a situation favored by a high pressure system in the Eastern United States, maintaining high pressure values on the region and in turn that said windy pattern persists. The speeds reach up to 125 km/h in La Cruz de Guanacaste, in the rest of the North Pacific they are around 50-90 km/h and in Central Valley the maximums are between 50-80 km/h.

Forecast: Windy conditions will prevail throughout this day, maximum speeds are estimated between 80-110 km / h in Central Valley and North Pacific, being in the high parts of these regions where the most intense gusts are experienced. Strong winds will also be felt in the mountains of the Central and South Pacific.

As for rainfall, during the remainder of the morning and during the afternoon, isolated rains are expected in the mountainous sectors of the Caribbean and the Northern Zone, accumulated between 5-15 mm. At night in these regions rains can be generalized and maintained intermittently with amounts between 10-20 mm. They are possible and drizzle in the north and east of the Central Valley, as well as in the north of Guanacaste, accumulated less than 5 mm.

Weather conditions will continue extremely windy over the country at least until next Sunday due to the migration and strengthening of the high-pressure system to the Atlantic Ocean.

Due to the above, the IMN recommends:

  • Extreme precautions due to 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).
  • Caution for boats by choppy sea and very strong waves in the North Pacific, Gulf of Nicoya, Central Pacific and the Caribbean Sea, as well as air navigation due to turbulence over the mountainous sectors.
  • Avoid burning of all kinds as they can get out of control.
