Storm weather

[ComradeP]

Assuming the storm MP multiplication stacks with weather, if a movement cost is doubled by the storm to a level that means a hex that would normally be reachable is theoretically no longer reachable because it costs too many MP's to reach, does the MP requirement switch to Max/all?

What happens to hexes that already cost Max/all MP's?

Let's say an infantry unit in Moscow 1942, which can normally move 1 hex in snow or frozen weather finds itself in a storm, what happens? Is it frozen in place?

What happens if it wants to enter a forest hex?
