IDK, when was the last solar radiation storm? Usually the atmosphere protects us from such apocalyptic events.
Hurricanes aren't global, but there's a reason you need an evacuation warning hours before they hit (even with motor vehicles). There are miles of effect that you can't just outrun.
Even if we take something more narrow like a tornado (and we're calling that a "storm"), "Tornado Alley" consists of the entire central USA. If you weren't lucky enough to already be in the specific vicinity, you aren't chasing that storm before it dissipates. It's not going to be practical to find your way to a specific spot for an occasional event, and if it's always there it's not a "storm" it's a "region". It doesn't work gameplay wise, nor as conceptually defined.
