Heat alert levels
- Green (summer preparedness): no alert will be issued as the conditions are likely to have minimal impact on health. However, during periods where the risk is minimal it is important that organisations ensure that they have plans in place and are prepared to respond should an alert (yellow, amber or red) be issued.
- Yellow alert: the heat is unlikely to impact most people; however, those who are particularly vulnerable (e.g. the elderly with multiple health conditions and on multiple medications) are likely to struggle to cope, and action within the health and social care sector is required.
- Amber alert: there is the potential for the whole population to be at risk. The expected impacts are likely to be felt across the whole health service, and other sectors may also start to observe impacts.
- Red alert: there is significant risk to life for even the healthy population. Several impacts are expected across all sectors.
