# You must first set the control panel in CDE to "no background"
# if using this script in Solaris. Takes various radar screens for
# Central Florida and updates the background. I run this as cron
# every 5 minutes during daytime hours.
#
# Requires Lynx, XV and the Netpbm tools installed if using Solaris. 
# Look at Sunfreeware.com
#
# Otherwise under Linux use xloadimage
#
# For a complete listing of radar sites consult http://inscoe.org/wx

# Updates:

# April 2, 2003
#
# Recently this script has been moved to my Redhat 8 desktop but should still
# work on a Solaris desktop. It previously worked under Solaris 8

# Now durng Hurricane Season switch off between local radar and storm track
