Re: Noel Moving Northward - Tropical Storm Warnings up for South Florida

The NHC did an "ok" job, I mean Noel was really not that easy to predict. Seems like Noel might ramp up into a Hurricane before it goes Extratropical. With how deep the convection is with Noel, you could say this resembled a Western Pacific system. Noel should continue the NNE motion for a while until it really starts to feel the trough which is swinging through the Northeast fo the USA right now. You can really see it on water vapor.

Here's the current steering map for Noel (990- 999 mlb)

This is why I see a NNE motion for the afternoon.. still needs to catch that trough.. wouldn't be surprised if the 2 p.m. has it moving back to the north. We'll see what happens with Noel as it should recurve either tonight or tommorow morning.
lasly, I want to note that there is a moderate Anticyclone over the storm, the same one that we saw in the Western Carribean..

You can see the strong clockwise motion.. This is a good reason why shear isn't destroying it
