Unfortunately, the earlier post erroneously (and dangerously) intimated that a pressure must be below 900 to cause catastrophic damage. This is a an uninformed, false statement.
Some people!...For those who tend to want to stay put, they should keep an eye on the millibar readings. IF it gets down to under 900, it might just be too late. I really resent having strangers malign what I’ve tried to say. Get it straight, people, okay? I did NOT say something by not saying something else first. Communication doesn’t really work that way, but miscommunication does.
