I can not tell you anything about the GFS model, but I can tell you that a frog tried to get into my house last night and even when I was nudging him out he was insistent upon entering and did so. Then this morning I saw a large beetle which are not seen around here except when the weather is changing drastically. The only thing I can say about it is that last week a slug appeared on my patio window and we got some of Arlene. The more anomalous creatures to my area of the city, the more liklihood of a US impact. My Lab eventually treed the frog so to speak on the patio curtain. The signs are there....
