Euro model shows lowest impact. Consensus model would have 4-8" up and down the 95 corridor, much more along the coastlines, particularly the Outer Banks and Cape Cod. One outlier model has 25-30" as far in as DC. All these models are trying to predict the center path of the storm, which is still in the Gulf and has to cross over Florida before turning north so very hard to read at present. "Max Velocity" talks about the different models in a bit of depth.
