Today we also mark another historic moment. And we again look warily at some menacing skies.

In New Orleans, they continue to put their lives back together three years after Katrina rumbled ashore and changed the Crescent City – and the nation – forever.

Now almost to the day, another storm is rumbling in the Gulf. The fear is that Gustav will mimic Katrina and lash New Orleans.

Many of the ceremonies to mark the third anniversary are being brushed aside today as the region braces for Gustav.

The National Guard was beginning to arrive in New Orleans, and some nursing homes and hospitals were beginning to move patients inland.

Just where Gustav will come ashore is not really known yet. Forecasters say it could hit anywhere from the Florida Panhandle to the east coast of Texas. But when it does, it likely will be packing a punch, possibly as a Category 3 hurricane with winds of 111 mph or greater.

Say a prayer for the good people of New Orleans, and the entire region, that they are spared a repeat of the nightmare from three years ago.
