Weather Warning

Windy conditions in Costa Rica

January 8th, 2020
10.30 a.m.

Diagnosis: The passage of cold surge # 15 through the north of the Caribbean Sea, causes the trade winds to perceive very large parts of the country. At this time maximum windgusts between 94-102 km/h have been recorded in Guanacaste and in the Central Valley between 70-81 km/h. In addition, weak and scattered rains have been recorded in the plains of the North Zone and the North Caribbean, with amounts accumulated between 5-10mm since midnight.

Forecast: Because of the cold surge, very strong windgusts are forecast in Central Valley and Guanacaste Plains, with values ??between 60-80 km/h; while, in the northern sector and the North Pacific mountain range, intense wind are expected between 90-100 km/h.

On the other hand, there will be occasional rains throughout the afternoon and evening in the Caribbean regions and the North Zone; In addition to light rains and drizzles in mountainous areas of the Central Valley and northern Guanacaste. On the contrary, in the lower parts of the Metropolitan Area and on the Pacific Slope, the rest of the day will remain under a stable and dry pattern.

The cold surge is projected to move rapidly to the Atlantic Ocean; Therefore, the greatest impact will be during this Wednesday and Thursday morning. However, weather conditions will continue extremely windy over the country at least until next Sunday due to the strengthening of a high-pressure system in the Atlantic

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 in areas vulnerable to flooding due to sewer saturation, increased flow in rivers and streams, and in areas prone to landslides.

• 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.
