There is absolutely nothing to worry about. It is very likely that in the near future the snake will go off food for months at some point.
I have a 14 year old Royal that has gone for almost a year without eating and didn't lose weight.
I don't know how often you feed but it isn't uncommon for a snake like that to go long periods without eating, followed by an increase in frequency.
Let the storm pass and feed later.
The snake will be just fine.
