Hurricane Irene & the Potential Rarity of a Georgia Landfall

As I alluded to in my previous post, the southeast needs to monitor Hurricane Irene. However the same holds true for the Mid-Atlantic as well since heavy rains and storm surge may be possible this weekend or early next week as it continues northward. In conversations with a couple of other meteorologists, I could not recall a hurricane making a direct landfall on the Georgia coastline in my 15+ years of tracking tropical storms and hurricanes. Turns out I was right. In fact, it hasn't happened in my lifetime. Here is an excerpt from a story posted online by The Augusta Chronicle last year in reference to Hurricane Earl:

Here is some background on Georgia's Hurricane History:
- Aug. 27, 1881: A major hurricane hits the coast, killing 700 people.
- Aug. 27-28, 1893: A major hurricane hits the Georgia and South Carolina coasts, killing 1,000 to 2,500 people and leaving 30,000 homeless.
- Aug. 31, 1898: The last Category 3 hurricane to date to make landfall in Georgia strikes Savannah, with 179 deaths.
- 1911: A Category 2 hurricane hits Savannah, killing 17 people.
- 1940: A Category 2 hurricane hits Savannah, killing 50 people.
- 1947: A Category 2 hurricane hits Savannah, killing one person.
- 1979: Category 2 Hurricane David hits Savannah, causing minor damage.

So that's 7 Georgia hurricanes in the last 130 years (average of 1 every 18.5 years) with Hurricane David being the last one in 1979. That's 32 years ago, which means Georgia is past due for a hurricane to make landfall. Interestingly, David's track (Source: Wikipedia) looks fairly similar to Irene's future track shown in my previous post.

That is really interesting that David's track is almost exact to the forecast track and current track of Irene. Really now just depends on when Irene makes that more northwest turn.

Well it was a nice parallel or a while. Looks like Georgia will be spared again. At this rate, maybe everyone on the East Coast will be spared from a direct landfall? Still looking like a heavy rain threat from the Carolinas to New England.
