How many trillion dollars have been saved over the years because we could track hurricanes. People are told days in advance so they can flee or prepare. The world knows who gets hit and can have help standing by ready to go in as soon as the winds die down.
Into WW2 many people got little or no warning. And assuming you survived the event the odds are people might not hear about it for days.
How true! The deadliest disaster in US history is considered to be the Galveston hurricane of 1900, which killed somewhere between six and eight thousand people. It came ashore as roughly a cat 4 with virtually no warning.
The more recent Galveston event was far less deadly, and those that remained on the island and perished at least had a choice.
In the 1970s, my brother lived briefly in Galveston. The walls of his living room still retained the high water mark from the 1900 storm.
