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...
Code:
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.

JIGDO-LITE(1)															     JIGDO-LITE(1)

NAME
jigdo-lite - Download jigdo files using wget SYNOPSIS
jigdo-lite [ URL ] DESCRIPTION
See jigdo-file(1) for an introduction to Jigsaw Download. Given the URL of a `.jigdo' file, jigdo-lite downloads the large file (e.g. a CD image) that has been made available through that URL. wget(1) is used to download the necessary pieces of administrative data (contained in the `.jigdo' file and a corresponding `.template' file) as well as the many pieces that the large file is made from. The jigdo-file(1) utility is used to reconstruct the large file from the pieces. `.jigdo' files that contain references to Debian mirrors are treated specially: When such a file is recognized, you are asked to select one mirror out of a list of all Debian mirrors. If URL is not given on the command line, the script prompts for a location to download the `.jigdo' file from. The following command line options are recognized: -h --help Output short summary of command syntax. -v --version Output version number. --scan FILES Do not ask for "Files to scan", use this path. --noask Do not ask any questions, instead behave as if the user had pressed Return at all prompts. This can be useful when running jigdo- lite from cron jobs or in other non-interactive environments. SEE ALSO
jigdo-file(1), jigdo-mirror(1), wget(1) (or `info wget') CD images for Debian Linux can be downloaded with jigdo <URL:http://www.debian.org/CD/jigdo-cd/>. AUTHOR
Jigsaw Download <URL:http://atterer.net/jigdo/> was written by Richard Atterer <jigdo atterer.net>, to make downloading of CD ROM images for the Debian Linux distribution more convenient. 19 May 2006 JIGDO-LITE(1)
