destructive winds are nearing florida s big bend region as we speak. idalia is about 50 to 60 miles away from the shore churning with 130-mile-per-hour winds. we just got that new forecast from the national hurricane center just moments ago and i want to go straight to derek van dam who is on the ground for us in tampa. s sara sidner is with us as well. derek, you understand what these forecasts mean better than anybody. what does this tell you? reporter: yeah, exactly what we feared, the rapid intensification now to a category 4 major hurricane idalia. and eyeing the big bend coast. but where i m standing now on bay shore boulevard in tampa bay is proof that you do not need to be near the center of where the storm makes landfall in order to feel its impacts. what you are looking at is storm surge from tampa bay.
