Rainy and electric activity in this afternoon

September 01, 2019

10.30 a.m.

Discussion: The Intertropical Convergence Zone is close to the country providing atmospheric instability with cloud cores near the Pacific coasts and combined with local factors such as warm morning temperatures and the entry of moisture from the maritime sectors, which are conditions that enhance the development of cloudiness in turn favoring precipitation events and thunderstorms during the afternoon and early hours of the night.

Forecast: During the afternoon, isolated but strong downpours are anticipated accompanied by a thunderstorm in the Central and South Pacific, Tempisque Valley and Nicoya Peninsula, amounts between 25-50 mm are estimated, localized upper amounts are possible. In the Central Valley, North Zone and mountains of the Caribbean, isolated rains and showers with thunderstorms are expected, they can occur of strong intensity in a timely manner, with accumulated between 10-30 mm.

For the night, isolated rains are expected with storm in the Pacific and North Zone, as well as possible weak rains in the Central Valley.

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 a high propensity for landslides.
• 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.
