3 to 5 inches of rain on how much time?
Have seen 4 inches of rain within an hour two or three times in my life I think. Thought it impressive. If it takes all day, it's just very wet.
Can't imagine the amounts they were foretelling for Texas. 35 inches? If that would fall here in the polder, on the whole surface of the polder, it would take weeks and weeks to get it all dry again.
