The reference to "just alerts" refers to the way the old WXSVR issued three 
diffferent classes of messages:  "Advisories", "Watches" and "Warnings" that 
would would light up transparent shape files in three different different 
colors (yellew, orange, red) on maps.

When AE5PL took over the APRS weather server in July 2009, he opted to 
drastically reduce the amount of traffic by dropping the advisories and 
warnings and send only the most urgent "Warnings" (severe events actually 
underway).
