Millions of people in Texas have been urged to limit their car use and share rides due to potentially unhealthy air pollution levels.
The Texas Commission on Environmental Quality (TCEQ) issued an Ozone Action Day on Wednesday for the Houston, Galveston and Brazoria areas.
Why It Matters
Elevated ground-level ozone pollution endangers the health of children, older adults, and people with respiratory conditions, exacerbating symptoms such as coughing, reduced lung function, and asthma attacks.
According to air quality forecasts, ozone pollutant levels are forecast to reach levels unhealthy for sensitive groups on Wednesday.

According to an air quality alert published by the National Weather Service (NWS), atmospheric conditions on Wednesday are expected to be favorable for producing high levels of ozone pollution in Houston, Galveston, and surrounding areas.
"You can help prevent ozone pollution by sharing a ride, walking, riding a bicycle, taking your lunch to work, avoiding drive through lanes, conserving energy and keeping your vehicle properly tuned," it said.
According to the TCEQ, ground-level ozone, or smog, is created when nitrogen oxides (NOx) and volatile organic compounds (VOCs) — released mainly from vehicles, industrial plants, and chemical solvents — react in sunlight.
Summer in Texas often brings stagnant, sunny conditions that accelerate these reactions.
What People Are Saying
AccuWeather meteorologist Brandon Buckingham told Newsweek previously:"Ozone is a secondary pollutant, meaning it's not emitted directly from sources but is formed through chemical reactions. These reactions require sunlight and higher temperatures, making warmer months more prone to ozone formation. When air is stagnant, pollutants don't get dispersed, allowing ozone to build up to unhealthy levels.
"Ozone pollution is often more severe in urban areas where there are higher concentrations of pollutants from sources like cars, power plants, and industrial activities."
Jonathan Grigg, professor of pediatric respiratory and environmental medicine at Queen Mary University of London, told Newsweek previously thatthere are "very clear links" between inhaling particles and earlier death from both respiratory and cardiovascular diseases.
He added that conditions such as asthma are exacerbated by exposure to air pollution.
What Happens Next
The TCEQ provides Ozone Action Day notifications one day in advance when conditions are expected to favor elevated ozone levels. This is so that "citizens, businesses, and industry can take steps to reduce the pollutants that contribute to ozone formation."
The Ozone Action Day alert remains in force throughout Wednesday.

Tropical Storm Erin 'Near Hurricane Strength' as New Track Issued
Based on facts, either observed and verified firsthand by the reporter, or reported and verified from knowledgeable sources. Newsweek AI is in beta. Translations may contain inaccuracies—please refer to the original content. The National Hurricane Center (NHC) has warned that Tropical Storm Erin is expected to strengthen and could become a major hurricane over the weekend as it shifts just north of the northern Leeward Islands, raising the risk of flash floods, landslides and life-threatening sea swells. Why It Matters Erin has the potential to become the first hurricane of the 2025 season. None of the four previously named storms—Andrea, Barry, Chantal and Dexter—intensified into hurricanes, but Chantal delivered heavy rains and flooding to North Carolina in early July. An NHC graphic showing the expected path of Tropical Storm Erin. An NHC graphic showing the expected path of Tropical Storm Erin. What To Know The NHC said Tropical Storm Erin was moving toward the west at a speed of nearly 17 mph on Thursday evening and it was expected to turn west-northwest overnight. "Erin is likely to move near or just north of the northern Leeward Islands over the weekend," the agency said. "Additional strengthening is forecast during the next few days and Erin is expected to soon become a hurricane and could become a major hurricane by the end of this weekend." The storm is expected to bring heavy rainfall beginning late Friday and continuing through the weekend across the northernmost Leeward Islands, the U.S. and British Virgin Islands, as well as southern and eastern Puerto Rico. Rainfall totals of up 4 inches—with isolated downpours dropping 6 inches—are expected, raising the risk of isolated flash and urban flooding, along with landslides or mudslides. Swells generated by Erin will begin affecting portions of the northern Leeward Islands, the Virgin Islands and Puerto Rico by this weekend. These swells are likely to cause life-threatening surf and rip current conditions, the NHC said. What People Are Saying Meteorologist Brooks Garner said in a post to X, formerly Twitter, on Thursday: "Tropical Storm Erin has strengthened and is expected to become a hurricane tomorrow. No significant changes to its forecast track…though we're watching the models closely to see if there are any changes to its expected curve out to sea." AccuWeather Lead Hurricane Expert Alex DaSilva said: "Do not underestimate the power of a major hurricane even passing by offshore. These massive storms produce very rough surf and lethal rip currents that can impact beaches even hundreds of miles away." What Happens Next The Atlantic hurricane season runs from June through November, while the eastern Pacific season began on May 15, also lasting through November. NHC says that August and September are typically the most destructive months of the Atlantic season.

Live Tracker Maps as Heavy Rain Takes Aim At Pacific Northwest
Based on facts, either observed and verified firsthand by the reporter, or reported and verified from knowledgeable sources. Newsweek AI is in beta. Translations may contain inaccuracies—please refer to the original content. A storm will bring heavy rain across parts of Washington state and Oregon beginning on Thursday night, a rare event for the areas during the summer dry season. National Weather Service (NWS) meteorologists are anticipating several inches of rain to fall over the course of the next few days, which could be more than a month's worth of rain for cities like Portland, Oregon, and Seattle, Washington. Why It Matters The forecast comes as meteorologists have warned that climate change has contributed to the prevalence of 100-year and 1,000-year floods across the U.S. in recent years. As the atmosphere warms, it gains the ability to hold more moisture, which in turn can fuel heavy rains when storms roll into the area. Such rains have brought devastating flash floods to many parts of the U.S. this summer, including Texas, Wisconsin, and Tennessee. A map from shows heavy rainfall over the next three days across parts of Oregon and Washington. A map from shows heavy rainfall over the next three days across parts of Oregon and Washington. What to Know On Thursday afternoon, NWS Seattle issued a hydrologic outlook for western Washington that warned of the incoming rain. "A frontal system will move across the area Friday into Saturday across western Washington. Through Saturday afternoon, 3-5 inches of rain are expected across the mountains, with 0.5-1.5 inches expected through the lowlands," the outlook said. Animated weather footage from showed that through Saturday evening, some parts of Washington could see around 3.5 inches of rain. Some rainy weather has already started near Vancouver, British Columbia, as of 5 p.m. Eastern time, the maps showed. Rain is expected to begin as soon as Thursday evening, AccuWeather reported. Much of the region is undergoing some level of drought, which could contribute to the flood potential from the incoming storm. "Very dry antecedent conditions has left the area soils dry and hard. This amount of rainfall in one storm will not have much time to soak into the very dry soil, which will result in heavy surface runoff," the hydrologic outlook said. "Impacts are uncertain due to how much moisture will be able to be absorbed by the soil." What People Are Saying AccuWeather senior meteorologist Heather Zehr told Newsweek: "The biggest concern we have, because it has been dry, is that, especially in the higher terrain where there's going to be more rainfall, that it can lead to some flooding issues. We are looking for rain totals in some of those higher areas at 2 to 4 inches, and that can lead to ... some flooding issues and flash flooding issues." NWS Portland in a post on X, formerly Twitter: "The rain will ebb and flow, so expect some periods that are heavier rain, then lighter rain, it may totally stop and then start up again. The rain will move eastward out of the region by Saturday/Sunday at midnight." What Happens Next Rain could begin to fall as soon as Thursday night, but the brunt of the storm will hit on Friday and Saturday. NWS Portland urged people to make sure their gutters were clean and that people should be aware that some creeks and streams might run higher than normal after the rainfall.

Trump's Approval Rating With Medicaid Recipients Takes a Nosedive: Poll
Based on facts, either observed and verified firsthand by the reporter, or reported and verified from knowledgeable sources. Newsweek AI is in beta. Translations may contain inaccuracies—please refer to the original content. President Donald Trump's approval rating with Medicaid recipients has dropped a staggering 16 points since January, a new poll from Morning Consult shows on Thursday. Why It Matters The shift occurred as Republicans advanced major cuts to Medicaid in the party's signature budget legislation, a bill the president dubbed "the big, beautiful bill." Medicaid covers more than 71 million low-income Americans and serves as a cornerstone of health coverage for vulnerable populations. Recently, the Centers for Medicare & Medicaid Services (CMS) and Department of Homeland Security (DHS) reached an agreement that provided U.S. Immigration and Customs Enforcement (ICE) access to certain Medicaid user data, a move that raised privacy and access-to-care concerns among advocates and some officials. Critics warned that such measures could deter eligible patients from seeking care. What To Know In the poll, the president's approval rating with the group is 36 percent, a drop from 52 percent during the president's first week in office. Trump's disapproval mark is 55 percent, soaring from 34 percent during the same time frame. Morning Consult conducts the surveys weekly among 14,695 U.S. adults, including 3,134 Medicaid recipients. The poll has a margin of error of 1 percent to 2 percent. The survey noted that "The biggest political question facing the Republican Party ahead of the next couple of election cycles is whether it can consolidate gains made in recent years among lower-income Americans. In the wake of those Medicaid cuts, that sure looks like a very steep climb," Cameron Easley, Morning Consult's head of U.S. Political Analysis, wrote. The president's overall approval rating with U.S. adults in the poll is 44 percent compared to a 50 percent disapproval rating.

(Photo by) What People Are Saying Political analyst Craig Agranoff told Newsweek via text message on Thursday: "The notable decline in his approval rating among Medicaid recipients, signals growing discontent within a key demographic reliant on public health programs. This drop, sharper than among the general public, appears tied to Republican led efforts to cut Medicaid funding through legislation like the One Big Beautiful Bill Act, which accelerated the slide when proposed in March and enacted in July. "It's particularly concerning for the GOP, as it erodes support even among Republican and independent Medicaid users, potentially complicating efforts to maintain gains with working class voters ahead of midterms. If unaddressed, this could highlight vulnerabilities in Trump's coalition where policy impacts clash with economic promises." Independent Senator Bernie Sanders of Vermont posted to X on Wednesday: "Trump's 'Big, Beautiful Bill' is a direct attack on the 1 in 3 Americans with disabilities who rely on Medicaid for their health care. It cannot stand. We must work together until every American with a disability has the freedom, opportunity and respect that they deserve." Trump wrote on Truth Social in May: "Republicans MUST UNITE behind, 'THE ONE, BIG BEAUTIFUL BILL!' Not only does it cut Taxes for ALL Americans, but it will kick millions of Illegal Aliens off of Medicaid to PROTECT it for those who are the ones in real need. The Country will suffer greatly without this Legislation, with their Taxes going up 65%. It will be blamed on the Democrats, but that doesn't help our Voters. We don't need 'GRANDSTANDERS' in the Republican Party. STOP TALKING, AND GET IT DONE! It is time to fix the MESS that Biden and the Democrats gave us. Thank you for your attention to this matter!" What Happens Next The president's approval rating will continue to be tracked by numerous outlets and pollsters leading up to the 2026 midterm election season.
