The storm surge was 20 plus feet in Tacloban. That would mean you could drown on the second floor.
As for the usual complaints by western press:
Before you send in aid, you need for the winds to stop (which would be Saturday afternoon) and repairing the roads etc. Then you need to get there. Airplanes are fast, but limited. Roads are blocked. The sea has to be calm and the port needs to be open, and the roads from the ports/airports need to be cleared.
That takes time. So the country folks will get help from each other, or will die. Luckily, these things happen all too frequently, so they help each other.
