“Heat Dome” to cover the United States this week; how to stay safe in extreme heat – KIRO 7 News Seattle

A wide swath of the United States will experience extreme heat in the coming days as the humid weather will be “trapped” under a dome of high pressure, preventing it from moving.

The heat wave is expected to raise temperatures at least 5 to 10 degrees higher than average across much of the country over the next few days, according to the National Oceanic and Atmospheric Administration.

The thermal dome effect occurs when there is a strong change in ocean temperature from west to east in the tropical Pacific Ocean during the previous winter.

Here’s how the National Ocean Service describes it:

“Imagine a pool with the heater on – temperatures rise rapidly in the areas surrounding the heater jets, while the rest of the pool takes longer to warm up. Looking at the Pacific as a very large basin, the temperatures of the western Pacific have increased over the past decades relative to the eastern Pacific, creating a strong temperature gradient or pressure differences that drive wind across the sea. ocean in winter.

What happens next is that once the hot air reaches the west coast of the United States, it gets trapped under the jet stream flowing through the United States, creating a dome of hot air. It stays in place until the pattern is broken – usually a few days to a week.

As the heat increases across the country, there are steps you can take to stay safe. Of Loan.gov, below are some tips to help you stay safe during an extreme heat episode.

What to do in extreme heat

· Learn to recognize the signs of heat sickness.

· Do not rely on a fan as the primary cooling device. Fans create airflow and a false sense of comfort, but do not lower body temperature or prevent heat-related illnesses.

· Identify places in your community where you can go to cool off, such as libraries and shopping malls, or contact your local health department to find a cooling center in your area.

· Cover windows with curtains or blinds.

· Weatherstripping for doors and windows.

· Use window reflectors specially designed to reflect heat outwards.

· Add insulation to keep heat out.

· Use a motorized attic fan, or an attic fan, to regulate the heat level of a building’s attic by exhausting warm air.

· Install window air conditioners and insulate around them.

If you are unable to afford your air conditioning, inclement weather or energy related repairs, contact the Low Income Home Energy Assistance Program (LIHEAP) to help.

Be careful in extreme heat:

· Never leave people or animals in a closed car in hot weather.

· If air conditioning is not available in your home, go to a cooling center.

· Take cool showers or baths.

· Wear loose, light, light-colored clothing.

· Use your oven less to help reduce the temperature in your home.

· If you are outside, find shade. Wear a hat that is large enough to protect your face.

· Drink plenty of fluids to stay hydrated.

· Avoid high-energy activities or working outdoors during the midday heat, if possible.

· Check with family members, the elderly and neighbors.

· Watch out for heat cramps, heat exhaustion and heatstroke.

· Think about the safety of pets. If they are outdoors, make sure they have plenty of cool water and have access to comfortable shade. Asphalt and dark cobblestones can be very hot on your pet’s feet.

· If you use a mask, use one made of breathable fabric such as cotton, instead of polyester. Do not wear a mask if you experience overheating or have difficulty breathing.

Signs of heatstroke

Extremely high body temperature (over 103 degrees F) taken by mouth

Red, hot and dry skin without sweating

Fast and powerful pulse

Dizziness, confusion or unconsciousness

If you suspect heatstroke, call 911 or take the person to hospital immediately. Refresh yourself with all available methods until medical help arrives. Do not give the person anything to drink.
