Summary Notes

No Stress	No heat stress	HS <= 0
Watch	Low heat stress	0 < HS < 1
Warning	Heat stress accumulating	HS >= 1 0 < DHW < 4
Alert Level 1	Bleaching expected	HS >= 1 4 <= DHW < 8
Alert Level 2	Significant bleaching expected; mortality likely	HS >= 1 DHW >= 8

Bleaching alerts are only generated when there is a stress level change for a station.
The alerts are generated for affected reef regions, archipelagos, and/or jurisdictions, not for individual data grid points.
Your bleaching observations (including observations of no bleaching) are greatly
appreciated. Observations can be sent to coralreefwatch@noaa.gov and/or entered online via Coral Reef Watch.
Should you have any questions or feedback on our Satellite Bleaching Alert email system, please send an email to coralreefwatch@noaa.gov.
To view, change (stations, email type, etc), or end your subscription, please visit the Coral Reef Watch Satellite Bleaching Alert website.
