Population density on the Iranian path coast are herders and grazers peopled at 0 to 50 per square mile.
Another thought that occurs to me is the dust storms in that area are frequent, especially on the Arabian Penisula. I wonder how much dust this storm will get airborne and what that dust will do as it heats up and collects moisture?
I guess I sould also note that the Central Makran Range of mountains are just inland from that coast and as the storm rises up that range it will drop its load of moisture at an ever increasing rate with mudslides and flooding on a scale that will be unknown previously.
