Sahara dust restrains downpours
The passing of tropical wave No. 49 on Thursday brought rains that were strong in specific points, as the tropical wave lost intensity, due to the mass of dust from the Sahara that is in the Atlantic and the Caribbean, which gave us dry weather conditions since Sunday last.
This concentration of particles is compounded by the fact that in the middle and upper levels of the atmosphere we have had a significant decrease in humidity this week, which reduces rainfall throughout the territory, with the exception of the central and southern Pacific, where yes it has rained normally.
The IMN reported that in September the Central Valley had 2% less rainfall than the average and this October could close with similar levels.
