Notso,

a hurricane is actually a warm core low, where at upper levels air circulates CLOCKWISE in the northern hemisphere (high pressure). Just somethng you might consider when planning the most favorable side to plan/divert around a tropical storm or hurricane.
The strongest winds will be at the surface and diminishing with height (this refers to the horizontal wind speed, not to the updrafts/downdraft in the convection)
Except for the convective band closest to the eye, or for particularly severe hurricanes, the hurricane cloud tops are generally LOWER than for isolated severe thunderstorms in the same area (that excludes some isolated overshooting tops, which normally do not last more than 15-20 min). This means that it might be possible to overfly a large part of the hurricane (I believe this is what the hurricane hunters use their gulfstream for, data acquisition while overflying the hurricane. On the other hand, they normally use the props for penetration into the eye at lower altitude).
