The forecast track in basically unchanged since yesterday. Irma is expected to continue its west-northwest track going around the southern periphery of the mid Atlantic ridge of high pressure. Once it reaches the southwestern side of the high, Irma is forecast to turn northwest, then north and toward Florida in response to a trough of low pressure coming out of the continental United States heading towards Florida, which will erode the mid Atlantic high pressure ridge slightly. The center of the track is forecast to move over the eastern coastline of the Florida peninsula. However, pay attention to the cone of uncertainty now covers most of the state of Florida, except the panhandle.
