Forecast: In the remainder of the afternoon, rains of variable intensity and downpours with electrical storms are expected in the Pacific regions (the strongest in the north and south), Central Valley and North Zone, amounts between 30-60 mm are estimated , larger accumulated are possible in a localized manner. On the other hand, isolated rains with storms are expected in the Caribbean mountains, estimated amounts between 20-40 mm.
During the first hours of the night the rains will continue, especially in coastal areas of the Pacific, amounts between 25-50 mm.
Warning: Special attention due to the high percentage of soil saturation in the Central and South Pacific, Nicoya Peninsula and North Zone.

• 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.
