Answer 1:
It depends on what you mean by "dangerous".
Tornadoes are extremely lethal where they hit,
but the deadly part of a tornado affects a very
small area.
Hurricanes are huge, and can easily dwarf
tornadoes in terms of the damage and deaths they
can cause, but you're much more likely to survive
getting hit by a hurricane than a tornado.
Ordinary thunderstorms are just really common,
which means that the number of people who get
killed by lightning strikes is large compared to
the others.
Firestorms are probably the most deadly of all
if you get caught in one, but they're also the
easiest to avoid.
So yeah, it depends on what you mean.
