Rainy activity of variable intensity this afternoon and night

September 08, 2024

11.30 a.m.

Discussion: The Intertropical Convergence Zone remains active near the national territory, in addition to instability in the upper atmosphere; they create a very humid environment and ideal for the formation of cloudiness and the occurrence of rains of variable intensity during the afternoon and early evening.

Forecast: Rains of variable intensity and isolated showers with thunderstorms are expected during this afternoon and the first part of the night period, starting in the mountainous areas and progressively extending towards the lower areas of the Pacific, Northern Zone and Central Valley regions. For its part, in the Caribbean, the probability of precipitation will remain in the mountainous areas. Estimated accumulations between 40-80 mm, in periods of 6-12 hours, higher accumulations are possible in a localized manner. In addition, fog banks are possible at the beginning of the night in GAM and mountainous areas.

Warning: Soils remain highly saturated in the North Zone, South Pacific and Nicoya Peninsula, regions where rain will be frequent on this day; therefore, these areas are highly vulnerable. Also, the rains expected in urban areas may cause congestion in the sewer system and flash floods.

Due to the above, the IMN recommends:

• Be careful due to sewer saturation in places prone to this type of flooding.
• Prevention in the event of an electrical storm and seek shelter in a safe place in the event of strong gusts of wind occurring or perceived near the storm clouds, due to the possible fall of tree branches, power lines, among others. These gusts can reach 80 km/h in some isolated cases.
