Weather portland heat wave is expected in many parts of the country, including Portland. Forecasters predict the hottest day in years, with temperatures climbing to 100 degrees or higher this week.
The National Weather Service has put Portland on the highest of 4 heat warning levels. Temperatures in the metro area should reach into the mid to upper 90s this weekend, and are expected to climb well into the 100-degree range Wednesday through Friday. Forecasters warn that the heat will be dangerous for anyone not taking precautions. Officials urge people to drink plenty of water and avoid strenuous activity outdoors. Too much exposure to the sun can cause heat exhaustion or even heat stroke.
Predicting weather Portland heat wave
Portlanders are bracing for an unusually warm and sunny summer, but it’s unclear if the heat wave will come in the form of warm, cool, or hot weather. This weekend’s forecast calls for temperatures near 80 degrees. But that doesn’t mean it won’t be a hot one. The National Weather Service forecasters say it will be “a very hot, very muggy and humid weekend.” They expect the temperature to reach at least 99 degrees at some point over the next few days. Over the long term, a ridge of high pressure will develop and remain over the area for several days. That means high pressure and lots of sunshine. However, forecasters say it will be “a fairly unpredictable pattern.”
Portland heat wave forecast Portland heat wave is projected to reach a maximum of 105 degrees on Wednesday, July 11. Forecasters predict the hottest day in years, with temperatures climbing to 100 degrees or higher this week.
The reason behind the heat wave
Weather portland heat wave are not uncommon in summer in the United States, but what makes the one currently entering its fourth day particularly frustrating is the city’s lack of air conditioning.
The state has almost half a million more households without A/C than it did 15 years ago. In 2000, about 7 percent of housing units in the state lacked central air. By 2015, that number had grown to 8.3 percent—more than double the national rate of 3.6 percent.
According to the U.S. Census Bureau, nearly a third of Oregon’s rental properties don’t have central air conditioning. And that’s especially true in Portland, where more than half of renters live in buildings without it.
Last weekend, the sweltering heat forced Portland’s River District, a dense neighborhood known for its funky boutiques and art galleries, to close its doors. “It’s crazy,” said Chelsea Russell, a researcher at the National Weather Service in Portland.
1. Due to global warming
Oregon is one of the hottest places in the country. According to the National Climate Assessment, Oregon is expected to be significantly warmer throughout this century. The report states: “the effects of climate change are already occurring in every region, ecosystem, and at all levels of society.
2. The ocean and air are not warming
The ocean and air temperatures in Portland are barely changing. The measured increase in Portland’s surface temperature is almost entirely due to an artificial rise caused by UHI warming.
The increase in temperature is not due to increases in air and sea temperatures, but to heat island effects.
3. UHI warming
Urban heat islands (UHIs) are cities and suburbs with more pavement, buildings, and other artificial surfaces. This leads to warmer air indoors, which can be felt as a sensation of heat.
Disadvantages of the heat wave
1. The increase in electricity bills
Electricity bills have soared as residents struggle to keep cool. One Portland home lost power for two days when the power grid overheated. Portland is one of the most expensive cities in the country for electricity, but that could be about to change.
2. The inability to go outdoors
Walking and biking will be more difficult in hot weather. This has been particularly difficult for construction workers. This has led to delays in new infrastructure projects. Therefore, the city has seen a rush on signs and banners to direct workers.
3. The health risks
A study by Oregon State University found that living close to the ground increases the risk of heat-related illness. Individuals who live closer to the sidewalk have an 80 percent chance of having a heat-related illness. Those who live in the middle of the street have a 50 percent chance, and those who live on the upper floors have a 25 percent chance.
4. The increase in deaths
The Weather portland heat wave has already killed three people in Portland and the state of Oregon, including one man on Sunday who collapsed while playing soccer. A heat wave in 1995 killed more than 4,000 people.
5. Dehydration and heat exhaustion
Drinking water is more important than ever this summer. During periods of persistent high heat and humidity, even small changes in daily routine can lead to dehydration or heat exhaustion.
People with chronic medical conditions are especially at risk. Heat waves can increase the risk of death from a heart attack, stroke, and other causes. A heat wave is a period of days or weeks when the temperature is abnormally high.
6. The danger of wildfires
Fires have raged in Western states over the past few decades due to changing climate. Wildfires are expected to become more frequent and more intense due to climate change.
7. The effects on commerce
Tourists are not coming to Portland during the heat wave, while businesses are being forced to close. Some businesses have decided to cut their losses and shut down during the three-day period.
8. The high cost of air conditioning
Poor and lower-income Portlanders are particularly at risk. However, the high price of electricity is forcing many residents to go without air conditioning. 9. The problems with the cooling centers
Some Portland residents have been forced to go to a cooling center. But the cooling centers have been overwhelmed and have limited hours of operation.
Conclusion
Weather portland heat wave has one of the worst markets for air conditioning in the country. Heat waves are natural and not caused by climate change as most people think. The real issue is the lack of an effective market for central air. If a central air system would only cost $20,000 instead of $35,000, very few people would be without air conditioning. We must protect the city’s urban core with aggressive building ordinances that mandate cool roofs and detached single-family homes within 3 blocks of transit.
