Weather warning

Heavy rainfalls in the Pacific will continue at night

August 6, 2019.
5.15 p.m.

Diagnosis: The Intertropical Convergence Zone is active over the country, reinforced by a disturbance in the upper part of the atmosphere, increasing atmospheric instability over the national territory. During this afternoon, the most intense rains are located in the Central Pacific and the South Pacific, and now they extend to the North Pacific. Amounts are estimated up to this time to estimate amounts between 30-40mm and maximum 60mm.

Forecast: In the following hours it will continue raining with strong intensity in the South Pacific and the Central Pacific, forecast amounts estimated between 20-40mm in the next 6 hours. Therefore, there are possible incidents with floods of ravines or ditches, mainly in the South Pacific.

In the North Pacific, there will be scattered showers with thunderstorms in the Nicoya Peninsula in the next 3 hours, with amounts between 15-30mm.

In the Central Valley, scattered rains are expected in the early hours of the night, with a thunderstorm due to Pacific precipitation. On the other hand, in the North Zone and the Caribbean, scattered rains are forecast between weak and moderate intensity during the early hours of Wednesday.

Due to the above, the IMN recommends:

• Caution in areas vulnerable to flooding due to sewer saturation, increased flow in rivers and streams, and sectors with high propensity for landslides. Special attention to the Pacific slope.
• Shelter in a safe place in case of hearing thunderstorms or perceiving strong gusts of wind near storm clouds, as well as precaution for possible fall of tree branches, power lines among others.
