In the mountain passes in the mountainous sectors of the Caribbean and the north of the Central Valley, as there could be small landslides on the road. In general, be alert to the development of storm clouds, which present their own significant characteristics such as descending gusts, high precipitation intensity in short periods of time and electrical discharges.

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.
