Weather Warning

Rainy activity in the Central and South Pacific will be extended to the early hours of the night

June 28, 2019
05.45 p.m.

Discussion: During this afternoon there has been strong rainy and electric activity in the Central and South Pacific regions, a situation favored by local factors of sea breeze intake and high morning warming, with maximum accumulated between 25-55 mm in the last four hours. There are also isolated showers in the Nicoya Peninsula, sectors such as Santa Cruz and Nosara have amounts of less than 20 mm in the afternoon period.

Forecast: In the early hours of the night moderate and strong intensity showers will be maintained with an electrical storm in coastal sectors of the Central Pacific (Parrita, Quepos and surroundings), as well as in the South Pacific (Ciudad Cortés, Osa Peninsula, Golfito, Ciudad Neily), amounts between 25-50 mm in lapses of 3-6 hours and more in a timely manner.

In addition, during the course of the night occasional rains are foreseen in the Caribbean and the North Zone, accumulated between 20-40 mm of 3-6 hours. For its part, significant rainfall is not expected for the Central Valley and the North Pacific.

Due to the above, the IMN recommends:

  • Caution in areas with vulnerability to flooding due to saturation of sewers, increased flow in rivers and streams and sectors with high propensity to landslide.
  • 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.
