Weather Report #8
Influence of cold surge # 17 on the country
January 21, 2020
10.00 a.m.
Discussion: The cold surge advances over Central America, at the same time generating strong winds in the north of Guanacaste, as well as in the mountain ranges with maximum speeds between 50-80 km/h, also cloudy conditions and rains in the Caribbean and the North Zone with accumulated between 10-30 mm.
Forecast: Strong wind gusts will be experienced throughout the day, with greater occurrence at the end of the afternoon and at night in the North Pacific, Central Valley and mountain ranges, with estimated maximum speeds between 40-80 km/h for the low zones and between 50-100 km/h in the mountains of both the Central Valley and the North Pacific.
With respect to rainfall, intermittent rains of variable intensity in the Caribbean and North Zone regions are expected, with amounts between 10-40 mm and possible higher accumulated locally. Drizzles are possible in the north and east of the Central Valley, as well as in the north of Guanacaste with amounts less than 5 mm. In addition, in the Pacific Ocean near the southern coast of Costa Rica and Panama, the Intertropical Convergence Zone has been activated and due to the proximity to the country it can cause short-term downpours in the afternoon mainly in the South Pacific, and to a lesser extent. measured in the Central Pacific, accumulated between 10-25 mm.
Due to the persistence of the rain in the Caribbean and the North Zone during the last days the soils are saturated; therefore, special attention is recommended to areas with vulnerability to floods and to be aware of the official communiqués of the National Emergency Commission, as well as of the official entities.
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.
- Caution in areas vulnerable to flooding due to sewer saturation, increased flow in rivers and streams, and in areas prone to landslides.
- Stay informed through social networks, Twitter: @IMNCR, Facebook: National Meteorological Institute and the Website: www.imn.ac.cr
