Extreme Wind Warning

• Product issued to convey threat of extreme winds
  associated with the eye of a major hurricane
• Was issued during Katrina, but then was under a
  tornado warning. Will now be its own product to
  reduce confusion.
• Criteria is that the hurricane must still be at
  category 3 strength (sustained winds 115 mph)
• Katrina was a high end category 2 when these
  products were issued in 2005
• Would probably only ever be issued for our far
  southern counties/parishes (Hwy 84 and south)
