I have just learned one of my co-workers in Northern Indiana (near Merrillville, 40 miles from Chicago) lost him home in the storm. Apparently he lives near a river and the levy gave out - his basement filled and water was chest high in his main living floor. He has three small children and wife, and all made it out unharmed - physically. Thankfully, he has flood insurance.
Also, my department has a team in Houston - we are unsure of their status at this point. I met them a few weeks ago and they are both very intelligent, so hopefully they had the good sense to leave.
Loss of power is small in the overall scheme of things.
