Karen, possibly a hurricane for something like three hours, maybe. My latest "Storm Pundit" post just went up--it's about Tropical Storm Karen, which was probably a hurricane yesterday for a very brief period and may be officially named one in post-season reanalysis (assuming the now-highly sheared storm doesn't make any kind of comeback). I point out that if Karen hadn't been in the Atlantic, I doubt we'd be able to look forward to this type of highly detailed reanalysis...and that's one of the key problem with hurricane datasets from around the world.
