Part of these rains will reach the west of the Central Valley and around the Gulf of Nicoya; with estimated amounts between 10-20mm and maximums of 25-30mm in a timely manner.

Note that, for tomorrow, Thursday, the arrival of tropical wave # 18 is expected; therefore, rainy weather in the country is expected to continue this day.


Warning: Special attention in the North Zone and the North Caribbean, mainly in the mountainous sector in the afternoon. In addition to the Central Pacific and the South Pacific due to the probable afternoon rains.

Due to the above, the IMN recommends:

• Caution in areas vulnerable to flooding due to increased flow in rivers and streams.
• 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 caution for possible falling tree branches, power lines, among others.
