Forecast: In the remainder of the morning, rains and downpours will persist in the South Pacific, South Caribbean, in isolation in coastal areas of the Central Pacific and the Nicoya Peninsula, accumulated between 25-50 mm.

In the afternoon, rains of variable intensity are expected in the Pacific and Central Valley regions, amounts between 30-60 mm, possibly larger accumulated in a localized way. On the other hand, in the North Zone and mountains of the Caribbean, isolated showers with electrical storms are expected with amounts between 25-50 mm. The rains will extend into the evening hours, especially in the Pacific.

Tropical wave # 47 is over Panama, its arrival in the national territory is estimated at night, which can lead to rains in coastal areas of the Caribbean and the Central and South Pacific during the night period from Wednesday to early Thursday morning.

Warning: Special attention to the high percentage of soil saturation in the South Pacific, Central Pacific, Nicoya Peninsula and the upper parts of the North Zone.

Due to the above, the IMN recommends:

  • Caution in areas vulnerable to flooding due to sewer saturation.
  • Take shelter in a safe place in case of hearing 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.
