In his weblog, Andrew Revkin reported that the dual activity of Hurricanes Gustav and Hanna pose a double threat to the Southeast and to the Gulf Coast.  As seen in this map, the hurricanes are close enough to each other to be considered a double system, perhaps like a double-star system.  As of Monday afternoon, Hurricane Gustav hit the Gulf Coast just west of New Orleans, while Hurricane Hanna is northeast of Cuba, and one possible track brings it toward Savannah, Georgia, although Hanna could move in any direction bringing to Florida or North Carolina.

As of Sunday afternoon, the activity of these two hurricanes was shown on the radar map printed below.

Radar maps of Hurricanes Gustav and Hanna

Gustav hit land just west of New Orleans in Cocodrie, Louisiana as a category 2 storm; however, flooding appears to be creating havoc in New Orleans.  Reports indicate that the storm is weakening as it moves inland, and of course this is a good sign for millions of people that have been displaced by this storm.  The latest radar for the storm is shown below:

This map shows Gustav just before landfall slightly west of New Orleans; Hurricane Hanna can be seen just Northeast of Cuba.

You can see in the map below the city of Cocodrie, south of Houma.  I’ve also included a video report made in Morgan City, just northwest of Houma.

At the bottom of the map you can see the city of Cocodrie where Gustav made landfall. Morgan City is located northwest of Cocodrie.

Update on Gustav as of 6:15 PM, September 1

Gustav, Monday evening (September 1) after it had reached the Gulf Coast just west of New Orleans. Reports at this point showed the levees were holding, but there was still some concern what would happen overnight.
