Does anybody know how typhoon Tembin will impact HKG this weekend? I'm flying HKT to HKG on Sunday, and taking HKG-ORD Monday morning. I'm worried that my flight to HKG will be cancelled, causing me to miss my flight back home.

Should I buy a cheap ticket from HKT-BKK, and then pay the UA change fee and fly BKK-NRT-ORD. Or am I worrying too much? Thanks!
