Weather Warning
Rainy storm conditions this afternoon in the Central Pacific and South Pacific
April 14, 2020
10.30 a.m.
Diagnosis: As usual in the transition period, the Intertropical Convergence Zone begins to approach Costa Rica, providing humidity and atmospheric instability to the national territory, creating ideal conditions for showers with an electrical storm this afternoon in the south of the country.
Forecast: Heavy storm showers concentrated in the South Pacific and Central Pacific sectors with amounts between 20-40mm and maximums of 60-70mm are forecast; part of these rains will reach the Central Valley and the Nicoya Peninsula in isolation. For its part, in the Caribbean regions and the North Zone, the partially cloudy sky will predominate with light rains in the upper parts. There is the possibility of rain in the early hours of the night, mainly in the South Pacific.
Due to the above, the IMN recommends:
• Caution in areas vulnerable to flooding due to sewerage saturation, especially in the South Pacific and Central Pacific regions.
• Take refuge in a safe place in case of hearing an electrical storm or perceiving strong gusts of wind near the storm clouds, as well as precaution for possible fall of tree branches, power lines, among others.
