Recently the New Orleans office of the National Weather Service hosted an Open House event. We got to see a weather balloon launched (video), meet a famous female astronaut and see the new emergency trailer. Always a teacher and always on the hunt for curriculum ideas, I was excited when the staff shared their new interactive web portal. They've converted all the old maps and made room for new data. According to them, they'll have lots of data in multiple formats for us map nerds to enjoy.
Check out the interactive mapper here: http://gulfatlas.noaa.gov/
