Wildfires expose millions in the Midwest and Northeast US to dangerous smoke

Heavy smoke from several large wildfires blazing in Canada and Minnesota is expected to engulf large swaths of the Midwest and Northeast U.S. this week, exposing millions of people to dangerous air pollution.

Minnesota officials issued an air quality alert from Tuesday through Friday for areas including the Twin Cities metro area, Alexandria and Two Harbors, with very heavy smoke expected across the state’s northeastern corner as large wildfires spread. Air quality levels in Two Harbors, the Tribal Nation of Grand Portage and other regions in northeast Minnesota were expected to reach hazardous levels, making it unsafe for everyone.

Dan Westervelt, associate professor at Columbia University’s Climate School, said severe drought conditions combined with heat in Canada and the U.S. have created “a perfect storm for really dry conditions to provide a lot of fuel for these wildfires to burn.” Research shows warming temperatures from burning coal, oil and gas are making fires more frequent and intense.

People should stay indoors as much as possible to avoid the extreme heat, especially as smoke moves in, said Tyler Hasenstein, meteorologist with the National Weather Service in Chanhassen, Minnesota.

“Those two things coinciding with each other is not good from a health perspective,” he said.

Officials in Michigan and Wisconsin warned residents Tuesday about air quality issues that could last for days. High levels of fine particulate matter in the air from wildfire smoke may be unhealthy for sensitive groups, such as children and people with heart or lung conditions.

In parts of Maine, residents were reporting a yellowish and brownish color in the sky. “There is plenty of smoke upstream, so expect periods of hazy skies over the next day before the cold front pushes through,” the National Weather Service in Gray, Maine, said on social media Tuesday.

By Wednesday afternoon, intense smoke will spread into the East Coast and Midwest, including parts of the New England coast, northern Pennsylvania, Detroit and Milwaukee, Hasenstein said.

Multiple counties in western and central New York were under an air quality advisory Wednesday until midnight. The most intense smoke could spread as far south as Washington, D.C., by midday Thursday, Hasenstein said.

Fine particle pollution from wildfire smoke can cause shortness of breath, coughing, dizziness or fatigue and aggravate heart and lung diseases and other chronic health issues. Experts suggest reducing or eliminating outdoor activities, wearing a N95 mask if you have to be outside and keeping your indoor air cleaner by closing windows and running an air purifier or air conditioner. Long term, exposure to fine particulate matter from wildfire smoke is one of the leading causes of premature death.

1 dead and 3 missing after boat carrying mostly family members sinks near Alcatraz Island

SAN FRANCISCO (AP) — One person died, three people were missing and 16 were rescued from the waters off San Francisco after a pontoon boat sank Tuesday afternoon while carrying mostly family members as part of a memorial service, authorities said.

Crews arriving on the scene near Alcatraz Island found a three-deck pontoon vessel almost fully under water with the motor still running and leaking fuel, San Francisco Fire Chief Dean Crispen said.

By Tuesday evening, authorities were searching for the missing in open ocean on the western side of the Golden Gate Bridge. The search, which involved divers, helicopters and vessels, was expected to continue all night, officials said.

Authorities updated the initial number of missing people from two to three after hearing from witnesses.

“Right now we are in full rescue mode,” Crispen said, adding that three people who suffered injuries falling from the boat were taken to a hospital and expected to be released Tuesday night.

Alcatraz Island, once a federal prison infamously inescapable due to the strong ocean currents and cold Pacific waters that surround it, is now a tourist destination. It is located in San Francisco Bay about a mile (about 1.6 kilometers) north of the city's shoreline, in an often windy area that attracts sailboats and other recreational vessels.

Videos of the scene showed boats deployed to rescue people who had been on the vessel, which was largely submerged with objects floating nearby.

The boating mishap was initially reported as a fire, “but we now don’t have any evidence of that,” Crispen said.

The person who died was alive when plucked from the frigid waters by rescue crews but later died. A dog onboard also died.

All those rescued were taken to Gashouse Cove Marina, a small craft harbor in San Francisco.

Aaron Anfinson, captain of the Bass-Tub, told the San Francisco Chronicle his boat was carrying guests toward the Golden Gate Bridge in “pretty windy, a little choppy” waters when a man on a smaller vessel flagged them down and pointed to a pontoon boat in the middle of the bay that appeared to be on fire.

By the time the Bass-Tub reached it, the flames were out, but the pontoon was sinking. Some people were already in the water while others remained aboard, Anfinson said, adding that they tried to hand out life jackets to the passengers.

One woman's head was injured.

“We figured we would get her first,” Anfinson said. A deckhand lowered a swim ladder and threw a life ring into the water to help pull her aboard.

“It was scary,” Anfinson said. “I don’t want to see anybody in that situation.”

Fire Lt. Mariano Elias said the vessel, described as a “pontoon pleasure boat,” was about 600 yards (about 550 meters) from Alcatraz and the emergency call came in just after 3:30 p.m.

Crispen said the vessel was believed to have launched near the St. Francis Yacht Club in San Francisco. A person who answered the phone there said the club did not have any information on what happened.

Live video from the scene showed a man and a woman wrapped in blankets and sitting on a curb before walking to a nearby ambulance. A yellow tarp covered a body on the dock.

The Coast Guard and Oakland police also helped in the rescue, Elias said.
