The heat that has brought sweltering temperatures to Long Island will continue through Saturday evening, followed by a cold front.

The National Weather Service said the heat advisory for Nassau and Suffolk counties would continue through 8 p.m. Saturday with temperatures expected to reach around 90 degrees, the weather service said Friday afternoon.

Elevated temperatures and high humidity can lead to heat-related illness, particularly in vulnerable populations. To beat the heat, people without air conditioning can go to the Island's cooling centers. 

The hot conditions are expected to break Saturday evening, though there's a chance of damaging winds, showers and thunderstorms in the late afternoon, the weather service said.

TIPS ON STAYING COOL

  • Stay hydrated with water and avoid sugary drinks.
  • Limit outdoor activity. If you don't have air conditioning, go to a cooling center or an indoor public place such as a shopping mall or library.
  • Keep pets out of the hot sun and provide unlimited fresh water.
  • Dial 911 immediately if someone is not sweating, their mental status is altered, and their skin is red, hot and dry. They could be experiencing heatstroke.
  • Check on elderly neighbors, who are vulnerable to extreme heat.

After that, the area is expected to dry out and have more seasonable temperatures, likely in the lower 80s. Similar weather will continue into early next week, forecasters say. 

"So, if we can get through this sort of speed bump with the heat today and tomorrow, I think the payoff will be nice for folks as we get into next week," said Dominic Ramunni, a NWS meteorologist. 

Friday's air quality was unhealthy for sensitive groups, the orange category. Saturday will drop to the yellow category, or moderate, then the green, or good, category on Sunday.

A heat advisory is the lowest level of warning, while an excessive heat warning is the highest level, according to the NWS.

Heat-related illness such as heat stroke, heat cramps and heat exhaustion are possible with prolonged outdoor exposure or physical activity, the weather service said. Forecasters warn the risk increases in vulnerable populations, including young children, seniors and those with preexisting medical conditions such as respiratory and heart ailments.

To reduce risk during outdoor work, the Occupational Safety and Health Administration recommends scheduling frequent rest breaks in shaded or air-conditioned environments, adding: "Anyone overcome by heat should be moved to a cool and shaded location."

For those planning to be outdoors Friday and Saturday, the weather service recommends drinking plenty of fluids, limiting strenuous activities to the early morning or evening, wearing lightweight and loosefitting clothing and being aware of the signs of heat exhaustion and heat stroke. These include: high body temperature; hot, red, dry or damp skin; a fast, strong pulse; headache; dizziness; nausea; confusion; and, in extreme cases, a loss of consciousness.

Anyone suffering signs of heat stroke should call 911, officials said, reminding: "Heat stroke is an emergency."
