is currently down. It is Albert Whitted. I have found that it is usually dead on for Lassing. Also, I usually add about 15% to whatever value and it's a pretty good approximation of what's happening at the SW from NNE to SE.

Once it's up and running again (I hope), looking at both it and the SW sensor should give us a very good indication of what is a goin' on

(Bayflite showed me this sensor)
