Does Taipei's Jade/Flower Market stay open in bad weather?

Does anyone know if it is still open if its raining…obviously not if there is a typhoon but what if its only raining. I’m leaving for home soon and this weekend is probably my last chance to grab some stuff.

I’ve seen the Jianguo flower market open in the rain before…

The Jade/Flower market takes place under an expressway, so it would be pretty well protected from non-typhoon rain. Have fun!
