I don’t like canceling classes. If there’s a chance that I can get to a class and that dancers can come I’ll try to get there -but yoga studios &c may close even if I am willing. Check with studio and Check relevant MeetUp sites for updates.
I set off for classes in DC area around 5 pm and I have no internet access after I leave home. You can always try me at 215-983-7036. If I don’t answer, it may be that I am driving. Willow Street Yoga announces closures 90 mins before class so you can check their site too.
In Baltimore, I live close by: only a power outage or heating failure would prevent me from holding a class, but heavy snow would prevent parking.
