Weather Warning
Gradual increase in trade winds
March 05, 2020
10.30 a.m.
Discussion: There is a gradual increase in trade winds over the northern and central part of the country, a situation that is caused by the increase in atmospheric pressure on the Caribbean Sea. In recent hours there have been gusts of up to 93 km/h in La Cruz de Guanacaste; in the lower parts of the North Pacific and Central Valley they are around 40-60 km/h.
Forecast: Throughout this day, moderate to strong winds will be maintained; Maximum gusts are estimated between 50-75 km/h in the Central Valley and between 65-95 km/h in the North Pacific, the strongest speeds will occur in the mountainous sectors of these regions.
Due to a significant decrease in the humidity contained in the atmosphere, the possibility of precipitation is extremely low in the course of this Thursday, to manifest itself will be towards the mountainous parts in the form of drizzles.
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, 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.
