Danny, Close Call?

You can see by the above graphic that Hatteras is on the edge of the cone of uncertainty on Friday night. This reddish/purple colored area is the possible path that Danny could take. The green line in the middle is the most likely path. The models mainly keep Danny offshore. However, the Navy model and the NAM (North American Mesoscale model) have been consistently bringing Danny across the Outer Banks region. Even a tad inland. The GFDL (Geophysical Fluid and Dynamics Lab Model) and most of the others keep Danny well out to sea. Here is a look at the latest forecast models:

Each line is a separate model. Again most of them swing Danny out to sea. Regardless of the track we will see some big waves again and a high threat for rip currents. I saw a mention of possible 10 ft waves across the Outern Banks in one of the discussions. Remember with Bill we were expecting 12-17ft waves. We probably saw 8-12ft near the shore based on photos and video with higher waves offshore. Rain will be heavier and more widespread if Danny moves closer to the coast. If it stays offshore, then the rain coverage will go down. Also, if Danny moves over Hatteras, then we will see possible wind gusts between 30-45mph. Mostly likely over the Outern Banks. If it stays offshore, then 20-30mph gusts at the highest. Winds of course won’t be as bad inland.
The reason Danny’s track shifted back west a little this morning was due to a western wobble. If this western movement continues, then the track will probably shift west as well. The motion is erratic and difficult to track. It’s probably going to be difficult for the models to get an accurate forecast until Danny becomes more steady. An upper level trough (dip in the jetstream) is expected to help bump Danny to the northeast on Saturday. That has not changed.
Stay tuned to WAVY-TV for the latest updates on Danny. Residents along the Outer Banks should at least prepare their hurricane kits. You should have it ready anyway, so now is a good time. Danny is moving over some warm waters. So it could strengthen into a hurricane in the next 36 hours. Everyone should monitor the weather over the next 24 hours. Especially coastal residents.
