What major US city (like top 50) would fare best?

In a major rain event such as Harvey: let's say 25 - 45 inches over 3 days covering a 50 mile radius around downtown...
I know that none would fare well, but some would fare better than others.

Doesn't Phoenix flood from an average rain?

Correct. Phoenix floods very easily.

Non-coastal cities would be obliterated due to design year events being around 25-year.....I'd surmise Seattle would do better than the average bear simply due to dealing with consistent rain fall. You could put Miami in that conversation as well or even higher.

I thought San Fran, but for some reason mudslides come to mind.

Vegas
Vegas has had to build these massive rain tunnels/sewage systems, because when they have a heavy rain event, it can immediately flood due to how dry the soil is and how rare it is.
If Vegas was hit by a Harvey I imagine it would be pretty bad.
Seems like a place like Denver would do ok.

My first thought was Miami or Tampa

Assuming just rain and no storm surge?
A city actually on the coast should handle it best since water doesnr have to drain far.
So maybe Miami

Does/would Denver drain well? It seems like there could be some big issue with mountain runoff

Trust me It will flood here too with 4" of rain

2013 Colorado Floods
...now imagine what 50" would do....

but they average >10 inches less a year than Houston does and 13 inches less than Harvey dropped in spots in Houston and Beaumont.

I'm guessing Seattle and San Francisco that drain directly out into the ocean.
I'm sure they both still have low points that would flood, but I bet it would be less impactful than in Houston.
I think Vegas would be the most fricked, since they have mountains on all sides, they are pretty much in a valley bowl... it would take a LONG time for all of that to flow into Lake Mead.

It's hard to say based on that, because that type of rain is even more abnormal in some areas than others.
Atlanta hit over 500 year flood levels in 2009 with 10-15 inches of rain.

I am going San Francisco. Sure there are parts that are going to get 20 feet deep, but there is a lot of elevation.
Places like the Marina district and probably Mission are going to get wasted, but Presido, Castro, Nob Hill, Pacific Heights should be fine. Most water is going to drain away from center.
This is all assuming this did not come with storm surge.

Its the closest large metro area I can think of that experiences higher than typical precip....
