Default Hurricanes - millibars vs in Hg

Early in Irene's development, I could have sworn the pressure was being reported in inches of Hg, now she's in millibars.

Anyone have an idea of why storms are in mb?

It's so that the French will acknowledge and report the storms. For example, Quebec will not allow a hurricane to enter if its pressure is reported in inches of Hg.

Storms are always referenced in millbars when in international airspace, once they coast-in, that's when you transition to in/Hg

Not sure if that's sarcasm or not, but

Intellicast - Hurricane Irene Current Track in United States

Shows mb.

Maybe it's up to the whim of the reporting agency. Just an anomaly I noticed. No worries, I think I'll sleep tonite

When the hysteria machine decides that it will be a big news item they probably prefer mb because the numbers are bigger, and therefore possibly scarier, to the couch potatoes watching on TV.
