General Review

Most of this week, rainfall will be usual during the rainy season due to the proximity of the Intertropical Convergence Zone to Costa Rica, although with little convection associated with it. Even so, it will be causing isolated but heavy rains near the mountains mainly during the afternoon and early evening.

Tropical wave # 35 is located over Venezuela and is expected to be crossing Costa Rica in the course of Friday, but this would not represent a significant increase in rainfall for that day.

By the weekend, there would be an increase in the intensity of the trade winds in the Caribbean Sea, bringing with this a mass of dust from the Sahara to Central America, which would mean a general decrease in rainfall in the country for those days. ; although rains are not ruled out near the coast of Limón, mainly during the early mornings.
