Hurricane Watch

Will Irene, lumbering up the coast earlier this week, lose her gumption and shrink from landfall as Earl did last Labor day weekend? Or will she gain momentum and pack a wallop the way Bob did two decades ago?

But despite big advances in hurricane tracking over the past 20 years, weather patterns remain just capricious enough to keep the skeptics among us skeptical and the planners preparing for the worst.
