Backup Script weird tar message

So I am working on a shell script to do a incremental backups. The 
script basically makes a full monthly backup then once a week makes 
another full back up with daily incremental backups. To limit the 
storage amount of backups, the script rewrites the weekly/daily backups. 
Eventually I want to add exclusions into it but that will be later 
(unless someone has some suggestions now). :p When I run the script to 
test it I get this message:

/bin/tar: Removing leading `/' from member names

I'm not sure whats causing it. I'm hoping some fresh eyes might see 
where I made my error.

The script looks like this:

# full and incremental backup script
#Change the 5 variables below to fit your computer/backup

COMPUTER=executioner                            # name of this computer
DIRECTORIES="/home/aingeal"                  # directories to backup
BACKUPDIR=/backups                              # where to store the backups
TIMEDIR=/backups/last-full                         # where to store time 
of full backup
TAR=/bin/tar                                                # name and 
location of tar

#You should not have to change anything below here

DOW=`date +%a`                          # Day of the week e.g. Mon
DOM=`date +%d`                          # Date of the Month e.g. 27
DM=`date +%d%b`                        # Date and Month e.g. 27Sep

# Monthly full backup
if [ $DOM = "01" ]; then

# Weekly full backup
if [ $DOW = "Sun" ]; then
        NOW=`date +%d-%b`

        # Update full backup date
        echo $NOW > $TIMEDIR/$COMPUTER-full-date

# Make incremental backup - overwrite last weeks

        # Get date of last full backup
        NEWER="--newer `cat $TIMEDIR/$COMPUTER-full-date`"
