A doe and two Joes

Forecast first
He bashes the NOAA press release from Monday that features the National Hurricane Center's forecast for the upcoming hurricane season. His beef is that a forecast for the number of the storms (predicted to be between 12-15, pictured on the left) provides "no added value" because it says nothing about if/where the storms will make landfall and what the damages will be. It takes him over 1300 words to say this. He alludes to AccuWeather's forecast and implicitly suggests it provides the "value-added" information NOAA does not. Let's evaluate what Bastardi and AccuWeather consider "value-added" information. Here are examples from the press release featuring AccuWeather's hurricane forecast:"Tropical activity in 2005 will again be above average," said Joe Bastardi, AccuWeather.com Hurricane Center Expert Senior Meteorologist and one of the world's leading hurricane forecasters. "The threat to interests on the U.S. mainland is greatest from North Carolina's Cape Hatteras to the mouth of the Rio Grande River."That sure tells me a lot, Joe. Your forecast encompasses a vast coastal zone where a huge percentage of the landfalls always occur.
"Property damage from 2005's storms is not expected to reach the magnitude of the devastating 2005 season. Bastardi projects total damage on the U.S. mainland to reach $6.5 billion in 2005."To attempt such a damage estimate is foolish. The amount of damage caused by a landfalling hurricane will depend heavily on exactly where it hits. For example, if one hurricane were to hit a major resort-area or city head-on during an inactive season, it could cause over $10 billion dollars in damage, easily. In an active season, if three hurricanes made landfall in sparsely populated areas, the damage may not exceed $5 billion. We cannot tell two or three days ahead of time whether a hurricane will hit within 100 miles of a given point. And 100 miles could make the difference between tremendous economic damages and relatively trival damages. So to make a damage estimate before the first storm has even formed is at best bad science, and at worst, irresponsible.
Yesterday, Dan mentioned that Channel 7 weekend meteorologist Joe Witte had been named "Dumbest Weatherman" by Radar Magazine. Regardless of what you think about Joe's on-camera presentation -- let the record show he's a smart guy. He has undergraduate and graduate degrees in meteorology from University of Washington, which is one of the best programs in the country. Furthermore, this is a highly respected meteorologist who has risen to the top of his profession, landing gigs in major media markets (NYC and DC). If you wanna talk about dumb, look at the person on the left part of the cover in Radar's next issue (no comment on the person on the right). Can this rag be serious when it calls itself "your source for fresh intelligence"?
