It’s not 100% but likely if 1889 were to cancel then your flight would be canceled. Delta would have 2 aircraft and 3 outbound flights. Usually they will cancel the latest but they could decide to operate the 2 ATL flights. The JFK forecast has changed yet again and they are now looking at a snow event. There are no weather issues for the two ATL flights. The JFK flight is 1910 leaving at 8:10. If a flight were to be canceled that’s actually the likely one. Keep in mind the BVI is one hour behind the US which does not help your decision. I would check both ATL flights in the morning and the JFK. In Snow events they thin the herd often the night before so a CNX should be posted well before that 8:10 departure time.
