On the Pacific slope, showers with thunderstorms are expected along the coast with estimated amounts between 50 mm and 70 mm with maximum amounts of 80 mm. The rains are expected to extend into the early evening.

Warning: Mountains of the Northern Zone and Northern Caribbean are prone to landslides due to high soil saturation and possible overflowing of rivers at the foot of the mountains.

Due to the above, the IMN recommends:

- Caution for sewer saturation in places prone to this type of flooding.
- Prevention before thunderstorms and seek shelter in a safe place in case of strong gusts of wind near the storm clouds, due to the possible fall of tree branches, power lines, among others. These gusts can reach 80 km/h in some isolated cases.
