Why doesn't it alert me when there's a hurricane?

I have a iPhone & I see many people get alerts on their phone saying there's a tornado, hurricane etc. How do I get those alert notifications. I went to settings and turned on emergency alerts but doesn't give me anything. Yesterday there was a tornado spotted around where I live. But got no notifications. Is there any app I can use?!

Messy story writing app/program?

I'm looking for an app preferably (android or iPhone) but a of program would work too, something to were I can see my ideas and move them around without to much effort, maybe something I can add images to.

IPhone 5 randomly shut off with battery still remanding

IPhone 5 randomly shut off with battery still remanding. Help?

Added (1). iPhone 5 randomly shut off and won't turn back on. Help?
I was in the car and turned it off regularly and went to check the time and it wouldn't turn back on. I didn't shut it down completely. The phone was on %50 and now it won't turn back on. My power button is broken and I usually use the button in the screen so I can't reboot it. I tried plugging it in to the charger but still nothing. Apple won't talk to me since my phone is not under their coverage. I can't afford a new phone right now.

Is the UK voltage bad for my iPhone?

So I'm traveling to the UK in a couple of days, London to be exact. But I've read about how the voltage is different, I have plug adapters but I know those don't change the voltage at all.
My iPhone 6 charger says it can take 110-240 voltage, and outputs 5.
I'm pretty sure this is safe but I'd like someone to please confirm, I don't want to fry my new device when I plug it in.
