My understanding is that an Atlantic Basin hurricane's path usually flows with the air flow around a high pressure area such as the Bermuda high. As Dr. Neil Franks once said "they follow rivers of air". My question is what isobar (pressure) will storms usually flow with? That is to say at what pressue does the high begin to push against the storm dictating its path?

That depends on how deep (strong) the cyclone is. A shallow system like a TD will be steered mostly by the lower layers, a deep system by the whole tropospheric column.

Here's a handy page with steering current analysis for various strength systems.

X-Y-NO,
Thanks for your response. I'll check out the references listed on the site and who knows I might take a shot at forecasting a track.

An unpublished study of EPAC storms showed that storms turning north tended to track between the 582 and 588 countours at H5.
