Hanna continues to frustrate folks here in Charleston from just northwest of Haiti as it does a little loop-de-loop (it’s already completed one) over the water, waiting for the high pressure system to build in, pick it up and whisk it off to the northwest. The good news is that it’s still on a slow weakening trend; this morning’s satellite image, depicted above, has her looking like a flat-out mess. The thunderstorms are fairly well-separated from the center; it’s amazing it’s maintaining 60 MPH winds as it interacts with Hispaniola.
Because The Turn hasn’t happened yet, we still are stuck in a wait-and-see pattern. This is frustrating because as NHC’s stated before, we won’t have any idea of exactly where landfall will happen until this thing starts to get going.
The 8am model runs showed a wild rightward shift in almost every model, probably as a result of Hanna’s eastern motion. Time will tell if this shift is anomalous or shows more of a permanent rightward trend. The 2am models started to demonstrate more rightward movement, but the 8am ones are the first time that I’ve seen the HWRF and GFDL models tack as significantly northward as they have.
The official forecast should look pretty familiar to you at this point, if not a smidge more rightward than previous tracks. Will be interesting to see what 11am brings.
I won’t be blogging all that often today; keep an eye to the Charleston Weather Twitter for updates throughout the day. I’m going to do a video briefing at 9:30 tonight; it won’t last too terribly long unless there are significant changes to discuss (and I’m willing to bet there might be). Back to waiting!
