Note: A bleaching alert for a Coral Reef Watch Virtual Station is generated
only when there is a change in the alert level at that station.
Definitions of Alert Levels:
--No Stress: No thermal stress (HotSpot <= 0)
--Watch: Low-level thermal stress (0 < HotSpot < 1)
--Warning: Thermal stress is accumulating (HotSpot >= 1 and 0 < DHW < 4)
--Alert Level 1: Bleaching expected (HotSpot >= 1 and 4 <= DHW < 8)
--Alert Level 2: Significant bleaching expected (HotSpot >= 1 and DHW >= 8)
A (+) or (-) in the subject line indicates an increase or decrease in the
thermal stress level from the previous alert issued for this station. The most
recent thermal stress levels issued for a station are included as reference.
