From NASA:

MCC-Houston has been shut down at 4:00am EDT this morning, and Hurricane
Lili contingency operations are in place and running. [The power-down
overnight was done in a slow, carefully deliberate process to minimize the
time that will be required for reactivating Mission Control (perhaps by
tomorrow night). Johnson Space Center itself, currently at Hurricane Prep
Level 3, has not been evacuated (this would be required by Level 2). ISS
operational control has been temporarily transferred to BCC (backup control
center) in Moscow, with HSG (Houston Support Group) at TsUP/MCC-M
maintaining US contingency telemetry and command contact with the ISS crew
via Russian VHF assets during the limited Russian comm passes. VHF comm
(voice only) can be acquired over the continental US via Dryden, White
Sands
and Wallops. POC (Payload Operations Center) in Huntsville is receiving
S-band return link through White Sands. The onboard Ku-band antenna is
parked to protect it from excessive cold.]
