New Voluntary Evac, south of Addicks, east of Barker. Mayor “strongly urges” people to leave, additional releases and tough conditions “for 10 to 15 days”:
Mayor threatens Mandatory Evac if people don’t leave voluntarily, drones monitoring activity, firemen knocking and looking in windows but not knocking down doors (if no signs habitation), affects “15,000 to 20,000 homes.”
That matches up with your calculation.
