csh Check if file exists on remote system

I've seen this question posed a few times with shell scripting, but have not found anything with csh. I am trying to download multiple txt files from a source using wget. These are archived tornado warning files; however, the files only exist if there were tornado warnings issued that day. I'm using something like...

set FILE = `whatever/YYYYMMDD.txt`
 
if (-e $FILE)
wget $FILE
else
continue
 

I know that the script as is will just check for the file in my directory, which obviously won't have it. Is there a way to check if a file exists online before attempting to download it? Otherwise, how could I do this (guessing it would deal with ssh)?

Thanks for your help.

You can always test the exit code ($?) of wget command (man wget)
Download will be tried before checking, but you will know that the file does not exist due to exit code test.

Thanks for your help, Peasant. I actually ended up finding another way to do this (just downloading all of the files and only using the ones I needed, since I delete them all at the end anyways). While it's a bit slower, it gets the job done.
