(Portland, OR)  --  Firefighters are mopping up after an early morning house fire.  Authorities say fire crews responded to the 5000 block of Northeast Alberta Court just before 2:30 this morning to find a fully involved house fire.  The blaze caused a nearby power line to fall and a gas meter to rupture.  Fire crews called Northwest Natural to come cut the flow of gas to the house.  Authorities say the two people inside the home made it out safely.
