The maps of Etna

What it shows

• The forecast wind from weather models at different altitudes above Etna, hour by hour over the next 24 hours.
• The direction towards which that wind would move suspended material at that altitude.

What it is not

• It is not an ash fall forecast: it does not indicate where, when or how much will fall, nor risk levels or arrival times.
• Real ash depends on the height and duration of the emission, the size of the fragments and how the eruption evolves.
