Weather Warning

Heavy downpours will persist in the early hours of the night

September 08, 2019
05.45 pm

Diagnosis: During this afternoon there are isolated but very heavy downpours in some parts of the Pacific, the west of the Central Valley and the mountains of the North Zone. The highest accumulated were in the Pacific, particularly in Orotina with 90 mm and Río Claro with 176 mm in the last 3 hours.

Forecast: It is estimated that for this night (mainly in its first hours 6-9 pm) isolated but very heavy downpours persist with thunderstorms in the Pacific and surrounding regions, with estimated amounts between 20-40 mm with maximums up to 60 mm In the Central Valley and the mountains of the North Zone, rainfall of variable intensity is expected with isolated thunderstorms with accumulated estimates between 10-20 mm and maximums of 30 mm.

For this Monday, the entry of tropical wave #32 to the country is expected in the morning, which will be leading to an increase in the probability of rain for this day.

Due to the above, the IMN recommends:

  • Caution in areas vulnerable to flooding due to sewer saturation, increased flow in rivers and streams, and sectors with high propensity for landslides. Caution on the main routes of the Pacific and Central Valley.
  • Shelter in a safe place in case of hearing thunderstorms or perceiving strong gusts of wind near storm clouds, as well as precaution for possible fall of tree branches, power lines or hail events, among others.
  • Stay informed through Twitter: @IMNCR, Facebook: National Meteorological Institute and the Website: www.imn.ac.cr
