The low pressure cell has slid down the coast of BC a bit and the winds are now mostly westerlies. Lots of rain. Not much migration. There are always birds trying to pick through and we can see them in the loops and confirm they are most probably birds in the HC loop.
This is a pretty well organized and slow moving low. I think we’ll be looking at more rain and north winds for a couple more days. The rain might let up earlier but the north winds probably wont. So it’s probably going to slow down the migrants a bit over the weekend.
