re: Authoritative Hurricane Ida Rainfall Map?

Also if you want a specific location you can go on wunderground Baton Rouge forecast and under the main title it will show a location and another link next to it that says ‘change’. Select that and it will open a map showing all of the weather stations they have access to. Once you select one you can look up the historical data at the bottom of that page with some drop down menus. Unfortunately though a lot of those stopped recording when the power went out for Ida, so it may be hard to get data for those dates.
