It definitely qualifies as does all animal or plant behaviour. We usually get a passing typhoon in May, so that's only a bit over a month away.

Had a weird thing happen with the mosquitoes on Fri night. Somehow they seemed to sense that a dong bei was coming coz the house exploded with mosquitoes a couple of hours before the wind change arrived - never seen so many inside - and no doors or windows left open. Assume they'd picked up something in the air that triggered the sheltering and feeding frenzy instincts.

Btw, that was a pretty decent wind. On my own Beaufort scale it was at the level where the deck chairs get blown off the the porch, and flip flops go missing.
