I copied this advisory from the National Weather Service. It was issued at 5:13 PM EST on Sunday afternoon. The only thing I changed was all uppercase to mixed case to make it easier to read.
URGENT – WEATHER MESSAGE NATIONAL WEATHER SERVICE NEW ORLEANS LA 413 PM CDT SUN AUG 28 2005
…Extremely Dangerous Hurricane Katrina Continues to Approach the Mississippi River Delta… …Devastating damage expected…
Most of the area will be uninhabitable for weeks…perhaps longer. At least one half of well constructed homes will have roof and wall failure. All gabled roofs will fail…leaving those homes severely damaged or destroyed.
The majority of industrial buildings will become non functional. Partial to complete wall and roof failure is expected. All wood framed low rising apartment buildings will be destroyed. Concrete block low rise apartments will sustain major damage…including some wall and roof failure.
High rise office and apartment buildings will sway dangerously…a few to the point of total collapse. All windows will blow out.
Airborne debris will be widespread…and may include heavy items such as household appliances and even light vehicles. Sport utility vehicles and light trucks will be moved. The blown debris will create additional destruction. Persons…pets…and livestock exposed to the winds will face certain death if struck.
Power outages will last for weeks…as most power poles will be down and transformers destroyed. Water shortages will make human suffering incredible by modern standards.
The vast majority of native trees will be snapped or uprooted. Only the heartiest will remain standing…but be totally defoliated. Few crops will remain. Livestock left exposed to the winds will be killed.
An inland hurricane wind watch is issued when sustained winds near hurricane force…or frequent gusts at or above hurricane force…are possible within the next 24 to 36 hours.
I was in New Orleans in late June. It’s a wonderful city. I hope there is something left by this time tomorrow.
