Record low pressure
The deepest storm of record is ongoing in the upper mid-west today, with both Minnesota and Wisconsin setting all-time record low pressures. Which of course brings up the question, what's the lowest recorded (sea-level) pressure in Alaska? Turns out that yesterday was the anniversary of the accepted answer, 925 mb (27.31 inches) at Dutch Harbor on October 25, 1977. The NCEP reanalysis though has MSL pressures more than 10 mb higher. No doubt this requires investigation.
