Fifty years ago this evening--on the night of June 26, 1957--residents of Cameron, Louisiana slept uneasily. Cameron, population 3,000, sat on the coast just above sea level, about 30 miles east of Texas. Hurricane Audrey
roared across the dark waters of the Gulf of Mexico towards Cameron that night, lashing the coast with high winds and heavy rain. Many residents had heeded calls to evacuate from Audrey's 100 mph winds and predicted 5-9 foot storm surge that afternoon. But the old timers, familiar with how the surrounding dunes had protected Cameron in the past, stayed put. It was, after all, June, and severe hurricanes in June were almost unheard of. Besides, the storm was not expected to hit until the following afternoon, so there was still time to evacuate in the morning if things looked bad. The remarkable mass exodus of thousands of crawfish from the marshes surrounding Cameron that night apparently did not concern the old timers, who figured they had more sense than crawdads. But the crawdads could apparently sense what the old timers could not--sea surface temperatures were a full 2-3 degrees Fahrenheit above average in the Gulf of Mexico, with a large upper level anticyclone bringing near-zero wind shear over Audrey. This perfect recipe for rapid intensification meant that Audrey was not going to be a mere Category 2 hurricane at landfall. An additional ingredient unfavorable for intensification--the approach of a trough of low pressure with increased wind shear--would not occur in time to weaken the storm. However, the approaching trough did bring an increase in steering current winds at mid- and high levels of the atmosphere, which doubled the forward speed of Audrey overnight.Figure 1.

Not everyone got the warning a hurricane was coming, since Cameron was isolated and didn't get good radio reception. Television sets were still too new to be commonplace. Those Cameron residents who were able to get the warnings saw this before they went to bed June 26:

Overnight, Audrey intensified rapidly, and more than doubled her forward speed from the 7 mph speed observed that afternoon. When residents of Cameron awoke on June 27, the escape routes had already been flooded by the storm surge. Audrey now packed top winds of 145-150 mph--an extremely dangerous Category 4 hurricane, the most powerful June hurricane on record. A massive storm surge of 12 feet swept through the bayous the morning of June 27, pushing inland over 25 miles. The final death toll will never be known, but it is thought 550 people--including over 100 children--perished in Audrey. It was America's deadliest hurricane disaster between the time of the New England Hurricane of 1938 (682 killed) and Hurricane Katrina of 2005 (1833 killed).Comparison of Audrey and Rita
Why was Audrey so much deadlier than Hurricane Rita of 2005? Rita hit the same region of coast with weaker winds (Category 3, 115 mph), but a storm surge even higher (15 feet). Rita destroyed virtually 100% of Cameron, whereas Audrey destroyed 75% of the town. Nearly two years later, Cameron is mostly just concrete slabs and trailers, thanks to Rita. However, Rita caused only one direct death in Southwest Louisiana--a drowning in Lake Charles. The answer is preparedness. Rita was a massive Category 5 hurricane several days before landfall, giving people plenty of time to receive the warnings and evacuate. Warning systems are much better now than in 1957, and Cameron was deserted when Rita hit. But Audrey did something hurricane forecasters still fear could cause a high death toll in the future, despite our better warning systems--rapid intensification with a sudden forward speed increase overnight, bringing a much stronger hurricane to the coast far earlier than expected. If this nightmare scenario happens to one of our major cities in the future, another Audrey-like death toll could easily result.Figure 2.

has photos of the memorial at the mass grave where hundreds of Audrey's victims are buried. I found this memorable poem by student Lucas Lasha on the website:
In '57 she began with a roar
No one knew she was comin' ashore
Most people were asleep in bed
Not knowing they should have fled.
After the fury of the storm's huge eye
Families cried for members who did die
Lady Audrey would long be remembered
As the fateful day that Cameron surrendered
