Just checked a couple of the webcams - http://www.bulgaria-hotels.com/en/pamporovo_webcam.html
and - http://snowshack.dyndns.org/ and things don't look too good out there. I notice the midstation webcam http://www.plovdiv.meteo.bg/en/pamporovo.php seems to be stuck on 11am yesterday morning which is not a great sign either.
Anyone out there got anything that might cheer us up - Heading out on 31st.
