As locals prepare a hot early July weekend, the National Weather Service on Friday issued an air quality alert for Long Island due to the high temperatures and humidity.
Automobile smog from Long Island's congested roadways could be one of the biggest dangers in the heat, as high temps keep the pollutant such as ozone close to the ground.
Temperatures across Long Island are expected to pass 90 degrees on Friday. A heat advisory is in effect for New York City, with 100 degree temperatures expected.
Locals should refrain from strenuous outdoor activity and keep close watch on small children, who can be more susceptible to negative effects of ground-level ozone exposure.
Temps should be cooler , especially those on the East End, where ocean breezes can bring some relief.
The state's Department of Environmental Conservation also offers the following tips in air quality alert situations.
• Use mass transit or carpool instead of driving, as automobile emissions account for about 60 percent of pollution in our cities
• Conserve fuel and cut exhaust emissions by combining necessary motor vehicle trips
• Turn off all lights and electrical appliances in unoccupied areas
• Use fans to circulate air. If air conditioning is necessary, set thermostats at 78 degrees
• Close the blinds and shades to limit heat build-up and to preserve cooled air
• Limit use of household appliances. If necessary, run the appliances at off-peak (after 7 p.m.) hours. These would include dishwashers, dryers, pool pumps and water heaters
• Set refrigerators and freezers at more efficient temperatures
• Purchase and install energy-efficient lighting and appliances with the Energy Star label
• Reduce or refrain from burning and attempt to minimize indoor smoking.
