Updated models from the ECMWF, Canadian and HWRF show large eastward shifts, making the forecast uncertain. Several forecasters have said that Irma could travel along Florida's east coast and avoid landfall. TTG FOX 5 Meteorologist Mike Thomas tweeted: “EAST SHIFT! Morning models turn Hurricane Irma just east of Florida similar to Matthew last year. If right, bad but not as bad as landfall.”
