Weather Warning
Strong wind gusts due to Cold Thrust #19
February 26, 2024
07:30 a.m.
Diagnosis: The displacement of cold surge # 19 (EF) over Central America and the Caribbean Sea is generating North/Northeast winds, with maximum gusts detailed below: North Pacific 76.8 km/h in La Cruz, Central Valley 46.5 km/h h in Santa Ana, North Zone 29.5 km/h Tenorio Volcano, Central and South Pacific 47.6 km/h in Cerro Chirripó and Caribe 21.4 km/h in Horquetas.
During this early morning and early morning hours the amounts of rain recorded in the Northern Caribbean and the Northern Zone do not exceed 7 mm.
Forecast: Cold thrust #19 will continue to advance through Central America and the Caribbean Sea this Monday and Tuesday. Today, Monday, moderate to strong winds are expected throughout the day and night in the center and north of the country, as well as in the mountain ranges. Gusts are estimated to range between 40-70 km/h in the Central Valley and lower parts of the North Pacific; While in the center/northern of Guanacaste and the mountain ranges the gusts between 70-90 km/h, gusts greater than 95 km/h could occur occasionally in the north of Guanacaste tonight. Current analyzes indicate that strong winds will extend to the center and north of the country for much of the week.
Regarding precipitation, the pattern of drizzle will continue in the mountains of the Caribbean and the Northern Zone this afternoon, although we could perceive weak rains during the night, with accumulations of between 10-20 mm in periods of 6-12 hours. . In addition, the possibility of drizzle is estimated in mountainous sectors to the east and north of the Central Valley. No precipitation is expected for the rest of the country.
The front and the cold mass of this EF will not reach our country.
Warning: Special attention due to very strong gusts of wind in the North Pacific and the Central Valley.
Due to the above, the IMN recommends:
• Prevention of wind gusts and their possible impact on roofs, electrical wiring, signs, trees; as well as in the mountainous parts of the country and Guanacaste (national parks, volcanoes).
• Caution in air navigation due to increased turbulence, as well as in maritime navigation due to increased rough seas, especially in the North Pacific, Gulf of Nicoya and northern Central Pacific.
• Avoid burning of all types, as they can get out of control.
