LONG ISLAND, NY — As the holiday weekend approaches, an extreme heat warning is now in effect until 9 p.m. Saturday, according to the National Weather Service.
Dangerously hot conditions with heat index values of 105 to 115 degrees are expected, the National Weather Service said.
Extreme heat and humidity will significantly increase the potential for heat related illnesses, particularly for those working or participating in outdoor activities, the NWS said.
"This is a multi-day extreme heat event with near record high temperatures and little overnight relief," the NWS said. "This level of heat can be deadly for those without adequate cooling and hydration. Impacts to transportation infrastructure and electrical and water systems are also possible."
An extreme heat warning means that the combination of heat and humidity is expected to make it feel like it is 105 degrees or greater.
Tips from the National Weather Service:
- Take extra precautions if you work or spend time outside. When possible, reschedule strenuous activities to early morning or evening.
- Know the signs and symptoms of heat exhaustion and heat stroke.
- Wear lightweight and loose fitting clothing when possible, and drink plenty of water, the NWS said.
- Seniors and those with chronic health problems or mental health conditions are at an increased risk, the NWS said.
- Homes without air conditioning can be much hotter than outdoor temperatures. Use air conditioning to stay cool at home or go to a place that has air conditioning. If you don`t have home air conditioning, continue to seek out cool spaces each day as long as it remains hot, and for a few days after if your home is still hot, the NWS said.
- Check on vulnerable friends, family members and neighbors.
- To reduce risk during outdoor work, the Occupational Safety and Health Administration recommends scheduling frequent rest breaks in shaded or air conditioned environments. Anyone overcome by heat should be moved to a cool and shaded location.
"Heat stroke is an emergency! In cases of heat stroke call 911," the NWS said.
