Do you really think that they checked the rain gauge every hour around the clock back in the 1800's? Precipitation intensity was very rarely recorded before electronic sensors, which have been deployed for the last few decades only.
I tried to check how far the hourly records go back. Apparently they go back to 1943. I don't know how complete that record is, but if it's complete, that's pretty impressive. In any case, that would be 78 years, not 152.
No idea, but some of the previous records are from that time. I'll have to recheck but 1903 holds the previous all time record and amongst the top 5, I think 3 of them are from before 1910. I think those old records are 24 hour records though.....here is what I foundhttps://nbc-2.com/news/2021/08/23/henri ... york-city/
This was from the storm before this one, it broke a daily record set in 1888. So the daily records go back to 1868
This one is for hourly records, which look like they started in 1943https://www.statista.com/chart/25690/ne ... l-records/
It looks like both daily and hourly records were broken but the hourly records only go back to half the length the daily records go back to.
