One other factor to take into account is the winds from the storm. Once the winds exceed 50 MPH, the RRs (in this case, CSX and possibly the CFRC/SunRail) have to start removing crossing gate arms at road crossings. They do this so the gate arms don't turn into dangerous projectiles if the wind rips them off the gate mechanisms.
Once the arms are removed from the gates, trains have to stop at each crossing and have a crewmember flag traffic at the crossing until the train moves across. This process, repeated at every crossing, takes so much time that it's nearly impossible to operate anywhere near to on-time.
The good news is that I have not seen any public information from Amtrak or CSX regarding any curtailments, shutdowns, or service disruptions. Your trip should be fine, and I hope it's a great one!
