It comes as worsening drought conditions across the Triangle are creating additional concerns.
Fire officials are urging people to take the heat seriously before finding themselves in a dangerous situation. The city's water department is also working to navigate the combination of extreme heat and drought.
Drought worsens
According to the latest state drought monitor update, nearly 30% of Wake County is now in a state of exceptional drought, along with nearly all of Durham County.
Stage 1 water restrictions remain in place in Raleigh. However, the city manager said water usage increased during the first two weeks of June as temperatures rose, warning the city could move to Stage 2 restrictions if that trend continues.
Durham has already implemented Stage 2 water restrictions.
Raleigh fire officials say the extreme conditions are also impacting their response, requiring more engines at each fire so firefighters can take longer breaks.
Officials are urging people to take common-sense precautions, including working early or late when it's cooler, wearing light and loose-fitting clothing and knowing the signs of heat exhaustion and heat stroke.
They also encourage people to check on neighbors, especially the elderly, and to stay hydrated early, noting that once someone becomes overheated, it can be difficult to recover.
What's next?
In Raleigh, officials say Falls Lake would likely need to drop to about 45% capacity before additional restrictions are put in place, but say all options are on the table right now.
