Heat Indices Up To 105: Hazardous Outlooks For The Hudson Valley

HUDSON VALLEY, NY — The dog days of summer have arrived with hot and humid conditions that have already resulted in hazardous weather outlooks for the region from the National Weather Service.

In a hazardous outlook issued Monday for southern Westchester County, the NWS warned, "There is a chance that some heat indices reach or exceed 105, which would result in Excessive heat warnings. The best chances for locations reaching 105, will be Wednesday through Friday."

A separate hazardous outlook for Orange, Putnam, Rockland and northern Westchester counties said heat indices there will range from the mid 90s to lower 100s Tuesday through Friday.

The separate hazardous outlook for Dutchess and Ulster says, " There is a chance for thunderstorms Tuesday through Friday, mainly during the afternoon and evening hours. Locally heavy rain from thunderstorms could produce ponding of water on roadways and standing water in low-lying areas. With increasing heat and humidity Wednesday through Friday, heat index values may exceed 95 degrees at lower elevations. Heat Advisories may eventually be needed during this time."

Stifling heat will also be found across the Lower Great Lakes and the Northeast the first half of the week, the NWS said. Excessive Heat Watches have been issued in the midwest.

A classic summer weather pattern will settle in through Friday, said Bill Potter of Hudson Valley Weather in one of his "campfire chats" on Facebook.

"Sunshine in the morning with a mix of sun and clouds for the afternoon and then we'll see developing scattered thunderstorms with the heat of the afternoon," he said.

Hudson Valley residents who need a place to cool off can go to an indoor mall. Senior centers, libraries and community centers often serve as cooling centers, but call before you go.

The Westchester County Health Department has already issued a heat advisory.

As humidity and temperatures rise, residents should avoid strenuous activity, drink lots of water, avoid alcohol and caffeine and cool off to prevent heat-related illness.

Sherlita Amler, MD, Westchester County Commissioner of Health, said people who are most vulnerable to adverse effects from the heat include the very young, seniors, people who are obese and those with high blood pressure, heart disease, diabetes or lung conditions.

Heat stroke is a serious and life-threatening condition that claims many lives nationwide each year. Symptoms include hot red, dry skin, shallow breathing, a rapid, weak pulse and confusion. Anyone suffering from heat stroke needs to receive emergency medical treatment immediately. Call 911 if you suspect heat stroke and immediately cool the overheated person while waiting for emergency help to arrive.

Amler reminded residents never to leave children, pets or people in a car. Temperatures can quickly rise to unsafe levels, so motorists should always look before they lock their vehicles.

“To avoid tragedy, it’s also vital to never leave infants, children, seniors or pets in a closed car no matter how brief the time,” Amler said. “Closed vehicles can quickly heat up to a life-threatening 140º F or more.”

Another concern during a heat wave is heat exhaustion. Seniors, young children, people who are overweight or who have high blood pressure, people who work outside or in other hot environments are most at risk. Frequent breaks and drinking lots of water can help prevent heat exhaustion. Signs include headache, nausea or vomiting, dizziness and exhaustion, as well as cool, moist, pale or flushed skin. Anyone suffering from heat exhaustion should move out of the sun and apply cool, wet cloths to their skin.

“During a heat wave, seniors, young children and people with compromised immunity especially should avoid vigorous outdoor activity, seek the shade, spend time in air-conditioned locations and drink lots of water throughout the day,” Amler said. “Especially when they’re swimming and playing in the water, children often forget to drink, so parents and caregivers should prompt children to take breaks to hydrate.”

Those who plan to travel by car should prepare their vehicle before hitting the road. Always travel with a spare battery, and avoid leaving radios, phone chargers and other accessories running when the engine is not. Check to make sure your air conditioning is properly functioning and coolant is at the proper level. If you plan to travel in less populated areas, bring water and an umbrella for shade if it becomes necessary to leave the car. Always keep air flowing throughout the vehicle, and try to park in the shade.

“Pace yourself — don’t overdo it in the heat,” said County Executive George Latimer. “If you spend a lot of time outdoors, take breaks in an air-conditioned place and drink lots of water. And during a heat wave, remember to always check in on your elderly or ailing neighbors.”

Elevated heat and humidity can also lead to unhealthy levels of ozone, a gas produced by the action of sunlight on organic air contaminants from auto exhaust and other sources. The New York State Department of Environmental Conservation forecasts daily ozone conditions at (http://www.dec.ny.gov), or call the New York State Air Quality Hotline at 1-800-535-1345.

The County’s Department of Emergency Services is monitoring the weather forecast, tracking the opening of local Cooling Centers and is in contact with Con Edison and NYSEG concerning the potential for power outages.
