The IBTrACS data on the UNCA website (
http://ibtracs.unca.edu/) is hosted by transferring data from NCEI to UNCA. Presently, there is an issue in the transfer (that is outside of our control) that has corrupted the transfer. We are hoping that the issue will be corrected soon and that the Sunday IBTrACS update will correct the situation (so data and tracks possibly restored on Monday).
If that isn't the case, then the IBTrACS team will look into the issue next week.
Thanks-

Note: IBTrACS data are updated Sun/Tue/Thu with data taking about a day or so to roll out to access at NCEI and browse-able at UNCA.
