Thanks for the great explaination! I'd been wondering about the eyewall replacement thing.
Maestri: pray for a slight move east; we will take a lick; good news is people left;we will be ready to recover;trying to help those who stayed by opening some last chance shelters; all our people left; fast approaching too late to leave--last hour or so; about 8 PM will start experiencing tropical storm strength wind;about 10% in Jefferson parish stayed ; not happy with that;some just thought they knew better; some residents of GRAND ISLE stayed--very very sad situation;potential for areas to be uninhabitable for weeks; worst case thousands die, city under water for months-with toxic water---but this is worst case, but this is a worst case storm--anything is possible;we will soon stop responding and will have to wait; "Pray. Pray Hard!"
