Well, DWV might not be a reliable indicator but the hundreds of varroa on my 
bottom board sure are :)  I guess since I don't really remember seeing DWV 
prior to varroa I usually associate it with the nasty little pests.   In all 
of my occurrences when I see DWV I have always had a heavier than usual mite 
fall.  This fall is the heaviest I have ever had.  My record book in front 
of me goes back to 1999 ( can't find the older one) and in no year do I have 
a mite fall that is this steady.  I currently am still seeing  way more 
mites on the bottom board than I should by now.  For 2 days the count 
subsided to around 15 in 24hr but then it jumped back up. I'm attributing 
this to the cool days.  By now though I would expect the count to be  less 
than a dozen. It is still more than I have the time to count between sips of 
beer :)  Oh well, be vigilant.
