The following comes from the NWS in Louisville, KY:
“Kentucky Emergency Management and Louisville MetroSafe have lifted the evacuation order and shelter in place warnings effective at 5:45 PM EST Sunday November 4, 2012. Crews have moved the hazardous materials from the derailment site.”
This means you can now go back into the 1.2 mile radius of northern Bullitt, southwestern Jefferson, and western Hardin counties in Kentucky.
A shelter in place warning they are referring to above was in effect for much of the day, as the removal of the hazardous chemicals was taking place. That warning also included portions of Meade County in Kentucky and Harrison County, Indiana.
