WESTCHESTER COUNTY HEALTH DEPARTMENT ISSUES HEAT ADVISORY
Advises Residents to Drink Water, Cool off and Never Leave People or Pets in a Closed Car
(White Plains, NY) – With extreme heat and humidity expected, and air temperatures anticipated to remain above 90 degrees on Tuesday and Wednesday, the Westchester County Health Department is issuing a heat advisory. As humidity and temperatures rise, residents should avoid strenuous activity, drink lots of water, avoid alcohol and caffeine, and take precautions to prevent heat-related illness. To help residents cope with the climbing temperatures, Glen Island Beach in New Rochelle will be open Tuesday, September 5 until 6:30 p.m., and Wednesday, September 6 from 11 a.m. to 6:30 p.m.; last entry is 6 p.m.
Westchester County Executive George Latimer said: “Pace yourself – don’t overdo it in the heat. If you spend 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.”
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.
Amler said: “Heat stroke and dehydration can take you by surprise. High humidity, chronic health conditions and some medications can also increase a person’s risk for heat stroke.”
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 alone 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 leading 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.
For tips to prevent heat-related illness and places to stay cool, residents can visit the Health Department website.
Residents who need a place to cool off can check the Cooling Center Finder. When it is too hot at home, senior centers, libraries, community centers and indoor malls offer a respite from the heat. Call before you go to be sure of the hours.
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. For air quality updates, go to airnow.gov. The New York State Department of Environmental Conservation forecasts daily ozone conditions, 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.
Since the last BA.2.86 update, lab and epidemiological data have trickled in. Many of us took a big sigh of relief after seeing specific results over the weekend.
Here is your update.
Three labs have already tested BA.2.86 in a petri dish. (The speed of scientific discovery for SARS-CoV-2 still amazes me). They found three main things:


All good news.
But, of course, what happens in a well-controlled lab doesn’t always reflect what happens in the real world. So, it’s essential to look at epidemiological data, too.
We continue to find cases of BA.2.86. The latest count is 39 samples in 10 countries. Wastewater systems have also detected BA.2.86 in the U.S., Switzerland, Thailand, and Spain. This means BA.2.86 isn’t a random blip on our radar and is spreading.
Our biggest question is around “growth advantage”:
How quickly is it spreading? Especially in the current landscape of high immunity? This will give us an idea of the timing and height of a BA.2.86 wave. Unfortunately, determining this is incredibly challenging today because we need enough cases in the same country, but our surveillance is down 90%.
(Editor’s Note: See the WPCNR exclusive report on undercounted antigen tests, resulting in undercounting Westchester cases by 65% in August Saturday September 2nd).
But three brave souls have given it a shot:
These initial estimates suggest that BA.2.86 isn’t spreading as fast as the original Omicron (which had a weekly growth rate of 400%) but faster than XBB. In other words, we won’t have a tsunami, but a BA.2.86 wave is possible.
This can change. These estimations have a ton of limitations and we just don’t have a lot of data points to go off of. And like we’ve seen before, a variant can gain or lose speed over time. Delta, for example, started really slowly in the beginning before taking off.

We’ve started getting answers about how well our tools work against BA.2.86, too:
We still have unanswered questions:
BA.2.86 has a ton of mutations, but the initial puzzle pieces look reassuring. We are at the mercy of time to see how this unfolds.
None of this changes the bigger story arc, though: SARS-CoV-2 continues to mutate and continues to cause illness and death. In fact, we are currently in a wave right now from Omicron subvariants. Regardless of what BA.2.86 does, our work for the fall/winter is already cut out. At the very least, get a COVID-19 vaccine this fall.

White Plains Public Schools opened this morning, but it may be the first day of school students in White Plains will be glad to go back. Temperatures are expected to be hot and humid and in the 90s, but for the majority of the 9 buildings in the district will be air-conditioned.
Motorists are encouraged to observe school bus rules and be aware of children crossing streets.
