Sand ash insurance in early June


Hello folks. I am doing in early June Ring road, Snaffelness and Rekyanes penisulla and maybe,but probably not Westfjords,

  1. Do you think that I need to take this insurance?

  2. How often sandstorms happened in this time of year?

  3. Is it possible to avoid it and be almost 100 percent sure if i monitor weather forecast and skip some parts where sand storms are possible?
