Water Vapor , Visible and Rainbow images of Debby. Debby has been downgraded to a Tropical Depression as of earlier yesterday evening. 

The most recent information from the National Hurricane Center is as follows:

.CENTER OF DEBBY TURNS SOUTHEASTWARD...EXPECTED TO RESUME AN EASTWARD MOTION LATER TONIGHT...


11:00 PM EDT Tue Jun 26
Location: 29.0°N 82.8°W
Moving: SE at 7 mph
Min pressure: 1000 mb
Max sustained: 35 mph

As we explained in the last update Debby was pretty much experiencing an influx of dry air into the center and high amounts of shear.. The shear continues to be a problem with Debby along with the fact that she has made landfall..

Here is the latest shear image and it is showing anywhere from 20 to as much as 30 knots of shear around the center of circulation.

On the steering currents above you are essentially seeing Debby between a ridge to the west and ridging to the east with a trough across the NE and just underneath this trough. However, this trough has created a weakness in the ridge in which Debby will be able to move thru and the trough should cause Debby to take a east and then ENE to NE track.

Once Debby re-emerges off the coast of Florida we expect her to intensify to a Tropical Storm again due to the warmer Gulf Stream Waters.

All guidance is essentially in agreement this morning with Debby passing close to but far enough away from the Carolinas to have minimal impact.

Further up the Atlantic we expect Debby to have no impact on Nova Scotia.

Latest images above do indicate some colder cloud tops so it is possible that at the very least Debby is maintaining her depression status if not potentially re organizing.

This is the final track and the final update on Debby. Starting tomorrow night we will be going back to severe weather and the daily 5 day forecast.
