A heat advisory means that high temperatures and high humidity will combine to create potential health risks.
The service warns people working or spending time outside to take extra precautions because of the heat, suggesting outside activities be rescheduled to early morning or evening hours. It also warns residents to be aware of the signs and symptoms of heat exhaustion and heat stroke, to wear lightweight and loose fitting clothing and drink lots of water.
