The prediction therefore points to precipitation in the form of locally strong showers, which will reach or exceed 15 liters per square meter in one hour. They are expected to affect mainly the north and the eastern region of the island.

The rains are of particular concern to the residents of La Palma, especially those most affected by the ash from the volcano. The geologist and spokesman for the Canary Islands Volcanological Institute (Involcan), David Calvo, explained to this newspaper that when said ash is soaked “it acquires a beastly weight” and can lead to the fall of weakened structures where there is an accumulation of material composed of fine particles of rock and mineral that the volcano spits. They can also reach the sewers if the water runs through the streets, but this is something “secondary” in the scenario envisaged by Aemet. “There is not enough level for floods to occur,” adds Calvo, a situation that would be much more worrying.

It is for this reason that the population strives to clean the ash as quickly as possible. In fact, the Los Llanos de Aridane City Council, through the municipal services councils, have confirmed the hiring of 20 companies for the cleaning of ashes in the streets of the municipality.

Thus, these contracted companies join a large device in which about 50 municipal workers work daily, from both councils; a score of volunteers, fire brigades of Gran Canaria; AXER Los Llanos de Aridane civil protection volunteering; Red Cross teams, and in recent weeks it has been counting on the support of the UME, “whose work is being very necessary since they are in charge of cleaning the scuppers preventing the rainwater system from collapsing,” the representatives emphasize. politicians of the City Council.
