Curtis,
You should already be "allowed" from
typhoon.atmos.ucla.edu
Devin, am I correct on this?
I believe we set this up about a month ago.
WSI is still a propriatary feed until Jan 01, 2001 at which time it will
be freely available. Until then you must arrange with WSI for individual
product/location distribution..
Yes, it is appropriate to contact Chris and Devin but please cc me so I
may maintain accurate records.
Thanks,
-Jeff
