this and even more so since the general "health" of the ice is what i'd call in a very "ill" state across the board
generally i think that since wheather conditions have a great impact on peak data and dates, the general condition of the system as whole will prevail in the long run and that said i think that:
a) the volume, indicatng the "amount of ice" totally present is very low and i suspect it's even lower than thought
b) the energy in the system in form of higher temps, ice, water and air, is significantly higher and sooner or later, the "right" weather conditions provided, will catch us all on the wrong foot, 2012 could serve as a harbinger here.
using the opportunity to thank you for you valuable work, last but not least for all the graphics and stats you're providing all over the place. checking daily :-)
