No. Stormcad is pipes and pipe networks, not storage or routing.
Conversely, Hydrocad doesn't do everything Stormcad does either. (unless Peter says otherwise) Hydrocad doesn't do pressure flow in pipe networks, modified rational method (where you change the Tc and re-figure the rational flow at each node), or auto-design of pipe sizes based on input criteria.
The newest Stormcad does a lot of fancy GIS stuff too, but it's bulky and annoying in my opinion if you're going to do anything less than a giant municipal project. Essentially it's twice as complicated so it can write "BIM" on the cover. Lots of stuff going that way nowadays.

HydroCAD and StormCAD are intended for different applications, so they have different sets of features. HydroCAD is a general H&H program, while StormCAD is primarily a pipe network program.
Although HydroCAD is not a dedicated pipe network program, it can can handle a lot of pipe calculations, *including* most of the items that beej67 excluded:
* HydroCAD can do pressure flow in pipe networks (when you select a tailwater-sensitive routing procedure)
* HydroCAD can do modified Rational method by adjusting the rise/fall rates and adjusting the rainfall duration for each point in the model (see the critical duration analysis)
* HydroCAD can automatically size pipes based on different criteria (see the Sizing tab on the Calculation settings screen)
The key issue in selecting between these types of tools is "what kind of analysis are you trying to do?" For a steady-state Rational method analysis with complex pipe systems, a dedicated pipe network program is probably the right tool. But if you have storage effects or need to route hydrographs, you'll need a H&H solution like HydroCAD.
