If it were a cyclone, I could understand... but just a rainy day?
When we were here in November '13, it had just stopped raining, and the transportation captain outside the airport was apologizing for the taxis being an hour behind schedule.
When Anchorage received 39" of snow overnight in 2002, the airport shut down... for 45 minutes. Then things went right back to normal.
Nope, I don't get it.
