NHC Shifts Track East - Debby Likely a Florida Storm

The National Hurricane Center shifted the forecast track for Hurricane Debby farther to the east. The present forecast takes the center of circulation nearly due north- towards Panama City, FL, although uncertainty regarding track and intensity still exists.

Former tropical cyclones that have followed a similar track have produced peak surge levels near Apalachee Bay south to around Cedar Key. High water levels in these storms often are observed near Tampa Bay/ Clearwater as well.

It's hard to find a tropical storm that tracked so slowly north in this area. Tropical Storm Alberto, however, did take a somewhat similar track at a slow pace, however, in 2006.

  1. It's interesting to note that this storm has had tidal impacts in Louisiana, even though it is weak, disorganized, and drifting toward Florida.
