Extreme Heat Warning, With 'Dangerously Hot Conditions,' Kicks Off Wednesday Across Long Island

LONG ISLAND, NY — An extreme heat warning remains in effect across Long Island, beginning on Wednesday.

According to the National Weather Service, the warning will be in place from noon on Wednesday until 9 p.m. on Friday. Then, an extreme heat watch will remain in effect from Friday evening through Saturday evening, the NWS said.

For the extreme heat warning, dangerously hot conditions with heat index values between 105 to 110 are expected, the NWS said.

For the extreme heat watch, dangerously hot conditions with heat index values up to 105 are possible, the NWS said.

The heat poses dangers, the NWS 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 has potential to be 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, the NWS said.

The NWS also offered tips:

- 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 heatstroke, the NWS said.

- Wear lightweight and loose-fitting clothing when possible, and drink plenty of water.

- Seniors and those with chronic health problems or mental health conditions are at an increased risk.

- 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.

- 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!" the NWS said. "In cases of heat stroke call 911.
