Danny Update: Lopsided Storm

Tropical Storm Danny's intensity remains the same mid-day Thursday, with maximum sustained winds at 60 mph. The organization of the convection is slightly better, but there is still no visible eye or symmetry to the storm, as one would expect from a "classic tropical cyclone." In fact, you could maybe tease Danny about being "naked" because the center of rotation at the surface is what we term "exposed." I.E., the convection is all shifted to the right of this surface low pressure center, and there aren't storms rotating around the entire "eye." Check out the visible image:

Weird, isn't it? This might be a result of the upper-level flow keeping some shear in the vicinity of Danny.

Here's the latest computer guidance for the track of Danny. The Tropical Storm is still expected to intensify to a Category One hurricane before transitioning to an extra-tropical cyclone later this weekend. Danny should pass just to the east of the NC and VA coastlines, bringing rough surf and steady winds of 15-30mph Saturday.
