this storm bears down. what's the very latest you're seeing on the forecast? >> we're just getting some data from the air force hurricane hunter aircraft flying through the storm. once we get a full set of data we'll have another update at 2:00 on exactly how strong dorian is. there's been some changes in the structure of the storm since last night but this is the first aircraft we've had in the air for some time so we'll get a really good estimate of how strong it is. right now the key thing to remember about dorian, it's a very powerful, major hurricane. grand bahama is still experiencing the eye wall and will many more hours. the storm is actually growing in size as we see today and that will expose more people along the florida east coast to dangerous conditions, winds and storm surge. >> reporter: there have been some signs of that northward movement of the storm, but even as that happens, the storm is getting bigger in size. what might that mean for the people in florida?
