Also a random ass Brit who looked for NJ advice about a year ago, and now I’m here!

There’s a bit of crossover for me - I lived in Hong Kong for a while, which included being there for some big typhoons. We didn’t have the temperature element that this storm has obviously, but the basics were the same - make sure you’ve got a few days of shelf stable food (enough for a couple of extra days beyond the expected storm duration), bottled water, charge everything, secure anything loose where possible.
