Particular attention to the Banano, Colorado, Coen, Telire, Barbilla, Chirripó, Matina, Valle la Estrella and Reventazón rivers as they are reported to be grown, as well as to the Sixaola River that is reported overwhelmed in the sector known as Las Parcelas.

  • Avoid burning of all kinds and that can get out of control.
  • Caution in areas with flood limitations due to sewer saturation, increased flow in rivers and streams, and in areas prone to landslides.
