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.

The IMN reported that in September the Central Valley had 2% less rainfall than the average and this October could close with similar levels.
