Two are better than one

Today is only the 2nd time in recorded history (the past 160 years) where the N. Atlantic basin has had two Category 4 hurricanes in existance at the same time (the other was at 0600 UTC 16 Sept 1926). (Thanks to Jeff Masters at Weather Underground for the interesting statistic!) Igor and Julia will likely weaken to Cat 3's later this afternoon (and may already be on their way down now), but the feat stands as a very unusual event.
