1. Matt Moreland National Weather Service New Orleans/Baton Rouge Marine Industry Day May 22, 2014 2014 Hurricane Season

2. Communicating Risk Isaac didn’t fit people’s preconceived notions ?

3. Communicating Risk • “This is just a CAT 1 hurricane” • “It has never flooded here before” • “I’ve been through Katrina and Gustav, this is nothing” • “I saw the news break into programming, that GFS thing says it won’t come here, phew!” • “This is the same surge forecast as Gustav and I didn’t flood then” • “My app has most of those lines way east of here. I like the one that says CLIPER” • “We are going to evacuate for all CAT1 hurricanes from now on” • “Ah great, I have a GIS map. Finally something accurate” • “We just had our 100 year storm last year”

4. Saffir-Simpson Scale • Categorizes hurricanes into 5 levels of intensity based on wind speeds alone • Ignores other threats such as wind duration, storm surge, heavy rainfall, river flooding, etc • No such thing as “just a category 1” or “only a tropical storm” • Can give people a dangerous and false sense of safety/security

5. Lead time is great… IF you have it. • National Hurricane Center Provides 5 Day Forecasts. • However, advisories are only issued when weather system has been classified as a tropical depression or storm. • Systems that develop in northwest Caribbean or Gulf may not always allow 5 days of lead time and preparation.

6. 2014 Seasonal Outlook El Nino Conditions Expected El Niño or La Niña Watch:  Issued when conditions are favorable for the development of El Niño or La Niña conditions within the next six months. El Nino tends to decrease the number of storms in the Atlantic basin
