“Warning Messages: Improving Response”…building “better” relationships to getthe “correct” response from warnings,advisories, forecasts, statements, andemergency messages!
All Storms Passing Within 65 nm of the Louisiana Coastline 1850s to early 2000s
Preparations: Multiple and periodic meetings with emergency partners focused on hurricane preparedness and safety, planning, and programming; Activities include: the President’sHurricane Week, NOAA Hurricane Hunter Tours,and Hurricane Exercises; past and historicalstorms, in-house retrofits, area conferences,public awareness, media assistance and workshops,and home industries activities. Other activities include:tourism, economic, environmental, and transportationinterests, family planning, etc.

PHASED EVACUATION
Size of storm influences storm surgeHurricane Charley Storm Surge with different size wind field
• Katrina vs Camille– Katrina was
much larger– Radius of
Maximum Wind (~eye) - 40 miles vs 7 miles
– Slightly different angle of attack
– Deep storm surge over larger area.
Our referenceto Camille inour productsproved critical.
What Made Katrina So DamagingWhat Made Katrina So Damaging• Unusual combination of
powerful intensity and large dimension– Category 5 Hurricane in the
mid Gulf on Sunday Aug 28 – max wind 175 mph.
– Hurricane force winds extended 90 to 100 miles east of the center.
– Hurricane weakened as it moved ashore but the wind field remained very large
– Large wind field contributed to powerful storm surge over wide area.
– Contribution of large wave development offshore prior to landfall also a factor.
– 55 ft wave ht recorded

Did we get the rightmessage to the “nth” person?Social Problems?…Yes, this happensin America. Katrinaspared no one andcrossed America’s social and economic borders. Over 60% of the deaths in Louisiana were said to be people over 76 years old! What message? What sirens? What flyers? Whatenhanced partnerships?
History repeating itself??????In the early 1900s, African Americans were heldon levees at gun point to assist in fighting floods.
The Problem!
This publication was written in 1915. The information on these two pages talks aboutrefugees and homeless as a result of the great flood of 1912 along the Mississippi River.The name of the publication is “the National Duty, Mississippi River Flood Problem,how it can be prevented” by John A. Fox prepared in 1915 for the Mississippi RiverLevee Association.
Over 6,000 homes in the city of Biloxiwere leveled. Over 280,000 LA areahomes were damaged or destroyed (Katrina and one month later with Rita in LA…28,000 in Andrew).
Although many evacuated (1.2million or more in Louisiana and Mississippi) and were safely sheltered(as many as 25,000 in the Superdome), the death tollfor the area was approximately 1300 people(estimated 2000 more have been reported missing).This is unacceptable. NOAA/NWS has to get the message to the “nth” person to get the ultimate goal
of no deaths.
Nearly 5000 boatswere lost impactingproperty and thefishing industry.
Post storm cleanup months laterrevealed bodies in attics and debris.
Brian Williams interest in weather helped. Robert Ricks, Senior Meteorologist and N.O. native, tells the story. Relationshipsmatter!
Relationships Matter!
A Great Relationship!Barter systemat its best!
Relationships Matter!
RELATIONSHIPS MATTER!Mr. Coleman held his store open to ensure NOAA/NWSmet our mission delivery… aiding the nation’s economy, being wise environmental stewards, saving life and property!
This picture says it all. Jake Herty, III, with Jake Herty, Jr. receiving his 35 yearFederal Service Award while being group briefed by Glen Covert and MarshaNolan (Employees Assistance Program). Jake, a New Orleans native, was thelone local NWS employee unaccounted for during Katrina. He took care of hisfather because he was fortunate enough to be well informed. Unfortunatelyothers do not have the luxury to be employed by an agency which has savinglives and property as its’ mission. Again, Relationships Matter!

Final Thoughts• Katrina combined powerful intensity
over a large area to produce a devastating impact to residents of Louisiana and Mississippi.
• Storm surge once again proved to be the hurricane’s most deadly agent in areas of low lying terrain
• Hurricane forecasts are improving…however errors in forecasted landfall location and intensity will continue.
• Upcoming Season….NOAA/NWS will issue an initial outlook for 2006 Hurricane Season in May.
• Hurricane preparedness is a year round activity in an area of high frequency of hurricane activity such as southeast Louisiana and southern Mississippi.
• The question remains, “What is the right message?”
