Revised list of 1.50” hourly rainfall in NYC:

hey Don when did NYC start measuring hourly rainfall? I thought it was 1943 for hourly rainfall and 1868 for daily rainfall? Thats what some sites mention anyway.  Has it just been a continuous hourly record of rainfall since 1943?

1943 on a regular basis, but physical records go back as far as 1889, with a few missing months. Daily records go back to 1869.
