Theoretically yes. Higher global temperatures mean more lobes of polar air will dive south in the winters. This could result in more snow in the winter and more rain in warmer climates.

Not saying it will be this bad every year. But more 100-year or even 1000-year flood events could become more frequent.

Should we expect flooding like this to become more frequent as temperatures continue to rise?

With all the dams and levees now built to control the rivers, each flood event brings more silt and fill into the river basin, thus lowering the capacity of the basin(s).

Consequently less rain and snow is required for a flood event. And in time flood events become more common, basins continue to shrink and a really bad rain event can set record floods even though they'd might not be more water.

Dredging can offset this problem some, but how much of the river system do they dredge?
