DISCUSSION
-----------------------------------
Fred has moved farther inland and is now located near the border of 
southwestern Georgia and southeastern Alabama. Between 0400-0600 
UTC, Doppler radar data from Tallahassee, Florida, still showed 
68-70 kt velocities between 9,000-10,000 ft associated with a solid 
band of convection in the northeastern quadrant. Using 50 percent of 
those values supported keeping Fred as a 35-kt tropical storm at 
0600 UTC. This intensity was also supported by 30-kt winds on the 
west side of the low-level circulation noted in surface 
observations. Since that time, however, the solid band of convection 
has become fragmented and the thunderstorm activity has broken up 
into more discrete cells. Satellite and radar imagery also indicate 
that the mid- and upper-level circulations have decoupled and 
sheared out to the north of the low-level circulation. As a result, 
Fred has been downgraded to a tropical depression at the 0900 UTC 
advisory time. Weakening will continue through today as Fred moves 
farther inland over Georgia and into the southern Appalachians, with 
Fred likely becoming a remnant low later tonight before merging with 
a frontal system over the northern Appalachians on Wednesday.

Fred has continued to move north-northeastward, or 015/12 kt. For 
the remainder of today, Fred should maintain a motion toward the 
north-northeast or northeast accompanied by a gradual increase 
forward speed owing to a very stable steering pattern between a 
deep-layer ridge to the east and a broad mid-tropospheric trough
to the west. The new NHC track forecast is essentially just an 
update of the previous advisory track and lies near the middle of 
the tightly packed NHC model guidance suite.

Although Fred is weakening, the system is still expected to bring 
flooding rains to portions of the southeastern and eastern United 
States during the next couple of days.
