The Mossos d'Esquadra fear that the rains will cause marijuana plantations to grow in the mountains.

The rain that fell this March has caused the rivers to run full like they haven't in a long time and has caused water to flow once again from the streams that had dried up. The news has pleased much of the country, but the Mossos d'Esquadra (Catalan police) who fight marijuana trafficking know that this increase in water greatly benefits traffickers who have marijuana plantations hidden in the Catalan mountains. The drought of the last four years has been a great ally of the police, since the greatest difficulty drug traffickers face in planting in the mountains is access to water. And this has, in fact, been the clue that has most helped the Mossos in their pursuit of this drug.
