Meteorological Warning

Rainy conditions during tonight - early morning in the national territory

Noviember 09, 2020
10:20 p.m.

Diagnosis: on Monday night  the entry of humidity from the Pacific and the present instability are factors that favor rainy conditions. During the last 3 hours, there were heavy rain conditions in the South Pacific, Central Pacific, and mountainous Caribbean regions. Places like Horquetas, Rio nuevo, coffee plantation El Indio, Juan Viñas, Montecarlo and Guayabo report accumulated 30-40mm in one hour.

Forecast: The conditions of strong downpours remain for the rest of the night and early morning, with a greater impact on the central and southern Pacific and the mountainous Caribbean. The Nicoya peninsula will have less intense rains in the early hours of Tuesday.

Warning: Special attention for possible incidents due to saturation of soils in the South Pacific, Central Pacific and mountainous Caribbean.

Due to the above, the IMN recommends:

• Caution in areas vulnerable to flooding due to sewerage saturation.
• Take shelter in a safe place in case you hear an electrical storm or perceive strong gusts of wind near the storm clouds, as well as caution against possible falling tree branches, power lines, among others.
• Stay informed through social networks, Twitter: @IMNCR, Facebook: Instituto Meteorológico Nacional CR and the WEB Page: www.imn.ac.cr
