Meteorological warning

Heavy rain with storm for the Pacific

June 5, 2019.
11:00 am

Diagnosis: Unstable conditions caused by the entry of moisture from the maritime sectors on the country generate the conditions for the occurrence of showers with thunderstorms.

Forecast: Throughout this afternoon and early evening hours rainfall of variable intensity accompanied by an electrical storm is forecast for the North and Central Pacific regions with amounts between 20-40 mm in 6-hour lapses, while for the Pacific South are expected to accumulate between 30-60 in periods of 6 hours, possible larger amounts in isolation. For the Central Valley, more isolated rainy conditions are anticipated with localized storms and amounts between 10-40 mm in periods 3 - 6 hours. It is possible that the rainy activity extends to the first hours in the night period, particularly in the Pacific slope.

In the Northern Zone and the Caribbean, isolated showers with a possible thunderstorm are expected in the mountainous sectors with accumulated between 10-30 mm of 6 hours.

Due to the above, the IMN recommends:

    Caution in areas with vulnerability to flooding due to sewer saturation, increased flow in rivers and streams and sectors with high propensity to landslide, particularly in the Central and Pacific Valleys.
    Shelter in a safe place in case of listening to thunderstorm or perceive strong gusts of wind near storm clouds, as well as caution for possible fall of tree branches, power lines among others.
