HURCON II sounds like
DEFCON 2, the 2nd highest level of five levels of The DEFense readiness CONdition (DEFCON); an alert state used by the United States Armed Forces.
The DEFCON system was developed by the Joint Chiefs of Staff (JCS) and unified and specified combatant commands. It prescribes five graduated levels of readiness (or states of alert) for the U.S. military. It increases in severity from DEFCON 5 (least severe) to DEFCON 1 (most severe) to match varying military situations.
Question: Does the Kennedy Space Center have formal levels of readiness for hurricanes that match the DEFCON's 5 down to 1 escalation, or is that a bit of humor mixed with the very serious message?
