States in the central and eastern U.S. are currently under extreme heat watches and warnings, as they brace for a dangerous heat wave in the first half of the week. The National Weather Service has issued alerts indicating an “extremely dangerous heat wave” expanding from the Midwest to the East Coast.
Over the weekend, the weather service issued extreme heat warnings in parts of more than a dozen states, with many individuals experiencing the highest temperatures of the year so far. In addition, extreme heat watches were also put in place in several states. The National Weather Service emphasized that the extended duration of the heat, evidenced by record warm morning lows, will make this period particularly oppressive.
The NWS Boston has cautioned that individuals will be more vulnerable to heat-related illnesses and advised caution when engaging in outdoor activities or working outdoors. This level of heat risk is considered rare and of long duration, posing a threat to those without proper cooling and hydration.
The heat index map highlights areas where the heat index is expected to reach levels from “Caution” to “Extreme Danger,” factoring in humidity to determine how hot it actually feels. Prolonged exposure to high heat index levels can lead to fatigue, heat stroke, or even death, with older adults, children, and outdoor workers at higher risk of heat-related incidents.
To stay safe during extreme heat, the NWS recommends staying hydrated, remaining in cool spaces, avoiding direct sunlight, checking on vulnerable individuals, refraining from leaving children or pets in hot vehicles, wearing light clothing, and limiting strenuous activities to cooler times of the day.
It is important to be aware of the difference between an extreme heat watch, indicating potential danger, and an extreme heat warning, signifying that dangerous heat is either occurring or imminent. Preparation is key in areas under extreme heat warnings.
In cases of extreme heat, it is crucial to take precautions to prevent heat-related illnesses such as heat exhaustion and heat stroke, which can have serious health consequences. Factors such as high humidity, elevated elevation, strenuous activity, age, pregnancy, obesity, and heart conditions can increase the risk of heat-related illnesses during extreme heat events.
During a summer heat wave, it is important to be aware of the symptoms of heat-related illnesses, with heatstroke being the most severe. Signs of heatstroke include a body temperature of 103 degrees or higher, hot and red skin, a fast pulse, headache, dizziness, nausea, confusion, and loss of consciousness. If someone is experiencing heatstroke, it is crucial to call 911, move the person to a cool area, and lower their body temperature with a cool cloth or bath. It is advised not to give the individual anything to drink. Stay informed about high temperatures and heat indexes by checking the map provided by USA TODAY.
