Heavy downpours with the possibility of flash flooding are heading to the Caribbean and northern regions of Costa Rica throughout the week as the rainy season progresses.

Authorities have issued a Green Alert for the Caribbean and Northern Areas warning that there could be the potential for landslides and flooding in the mountainous areas and river valleys. Although most of the torrential downpours will be seen in the Caribbean and the Northern regions, the south and Pacific coast will not be without some showers and lightning storms, also.

The rain is being brought in primarily by a low pressure system in the Pacific Ocean, and will being covering most of Costa Rica in showers. Areas that are likely to be affected the most include Reventazón, Chirripó, Banano, Sixaola, Pacuare, Colorado, and Frio Rivers. The Cano Negro Wildlife Refuge will see its lakes, springs and streams returning as the rain fills the momentary wetland, and fishermen and nature enthusiasts can get ready to boat in to the area for all the natural splendor that the area provides.

Gail force winds will also be a factor along with the flooding and electrical storms. Residents of the areas likely to be affected the most have been warned to stay indoors as much as possible during the storms.
