Canadian wildfire smoke is affecting air quality in Boston. Here's when it will improve.
Most of the air quality monitoring stations in our area are showing as "yellow," which corresponds to moderately unhealthy air. This is not enough for any real cause for concern, and there are not currently any air quality alerts in southern New England.
There have been a few stations with levels slightly higher than moderate, tipping into the "unhealthy for sensitive groups, " which means older adults, children, people with disabilities, and those with heart or lung disease should avoid outdoor activities, according to the EPA.

Why is the air quality bad in Massachusetts?
Again, the reason for this is twofold. First, there is some low-level ozone present on Monday. Second, and more importantly, some of the wildfire smoke from the ongoing Canadian fires continues to spill into New England.
This will come and go depending on the wind direction at both upper and lower levels of the atmosphere throughout the next few weeks and perhaps the rest of the summer, should the wildfires continue. The Canadian wildfire season typically spans from May to September.

When will the air quality improve?
Luckily, the smoke levels are forecasted to drop off significantly later in the day on Monday and on Tuesday.

We expect the air quality levels to improve and largely be in the "good" or "green" category by Tuesday.

Colorado's newest firefighting helicopter shelved for several weeks during wildfire season
In a case of bad timing, a helicopter purchased by the state for the specific purpose of fighting wildfires has been taken out of service in the middle of the summer fire season. The "state of the art" Firehawk is undergoing required regular maintenance, according to the Colorado Division of Fire Prevention and Control. An agency spokesperson told CBS Colorado the craft was taken out of service July 13 for thorough, mandated inspections. Several wildfires were ignited by lightning strikes on Colorado Western Slope the same day the Firehawk was taken out of service. Four of the larger fires - the South Rim, Turner Gulch, Sowbelly and Deer Creek incidents - are still burning. "We currently have 5 mechanics working on to get it back up and operational ASAP," CDFPC's Tracy LeClair stated. The normal duration of such inspections is several weeks, LeClair added. "We are hoping for sooner than that," LeClair stated. "They understand the urgency of getting us back up as soon as possible, without compromising safety." The Firehawk is a version of the military's UH-70 Black Hawk built by Sikorsky. The Si70i's wildfire conversion features a 1,000-gallon belly tank, extended landing gear, and a retractable snorkel that can refill the tank in less than a minute. Colorado ordered the aircraft following the 2020 wildfire season, one of the state's worst on record. The fires that year included the Cameron Peak, Pine Gulch, Grizzly Creek, Williams Ford, Middle Fork, East Troublesome and Calwood blazes. Three of those - Cameron Peak, Pine Gulch and East Troublesome - were the largest wildfires (in acreage) in state history. Colorado's legislature approved almost $31 million in 2021 for the purchase of the Firehawk and the leasing of other helicopters until its arrival. State officials celebrated the purchase in a press conference. "Not only will the Firehawk be an additional resource for aggressive and early initial attack," said Mike Morgan, Director of Colorado Division of Fire Prevention and Control, at that press conference, "but it can also be used on longer duration wildfires." The state's Firehawk recently reached 480 hours of flight time, necessitating the scheduled maintenance, CDFPC's Tracy LeClair explained. "The military has the same scheduled maintenance and is down the same amount of time to perform these Safety Inspections as required by the manufacturer," LeClair stated. "The critical nature of performing quality maintenance on an aircraft is not like an ordinary vehicle. It cannot be postponed, and one mistake, malfunction, or component failure can be catastrophic and fatal, unlike rolling to the edge of a road and waiting for a tow truck when your car breaks down." The maintenance includes some disassembly of the Firehawk to inspect the airframe, and the flight control systems and components running throughout it. Both engines will be removed during the process. LeClair confirmed a second Firehawk is on order. "We were planning to perform this inspection in the winter months, but we had no choice on this 1st helicopter," she said. "Once we have our second helicopter, we can stagger the maintenance to ensure one aircraft is available at all times. We don't have a solid delivery date for the 2nd one yet, but it is tentatively scheduled for delivery and acceptance late summer/early fall."

Powerful storm knocks down trees and damages homes in Massachusetts
After a strong thunderstorm moved across Massachusetts Sunday afternoon and evening, utility companies and tree crews were out that night surveying all the damage left behind. In Beverly, tree crews were out on Lakeshore Drive clearing streets of branches and leaves and chopping up the large trees brought down by the heavy rains and gusty winds. At least one large tree was ripped out of the ground and toppled over onto a home's driveway, crushing a car. Beverly Police said fallen trees have blocked off multiple roads. Late Sunday night, a little more than 250 customers were without power in the town. Police said they haven't received any reports of injuries from the storm. The Commuter Rail was also experiencing delays on the Newburyport/Rockport line due to downed trees on the tracks. For the latest on the delays, riders are asked to check the MBTA's website. Elsewhere, some communities like Framingham dealt with minor flooding from the heavy downpours. Late Sunday night, there was a little more than 1,000 customers without power across Massachusetts, according to MEMA. Boston and Belchertown have the most customers without power. The storm has since moved out and WBZ-TV meteorologists said the start of the week should be pleasant weather with low humidity and lots of sunshine. But there's potential for another heat wave later in the week, as temperatures climb into the 90s by the end of the week.

Climate catastrophes are creating a ‘new market reality' for insurance carriers
Raging wildfires and severe storms contributed to record-high global insurance losses — totaling an estimated $84 billion — for the first six months of the year, according to a report from reinsurance broker Gallagher Re. It has been the costliest first six months of a year since 2011, when insurance losses totaled $136 billion, the report said. Weather- and climate-related events amounted to at least $81 billion in the first half of 2025, the costliest on record for such events from January to June in a given year. Insurance losses are expected to surpass $100 billion for the entire year, Gallagher Re estimated. The report called this 'a new market reality.' US wildfires in January accounted for about $40 billion of the $84 billion total. The January wildfires that raged across Southern California were among the costliest and most destructive in Los Angeles County's history. It forced tens of thousands of Californians to decide whether they would rebuild their homes or relocate from a state increasingly facing the risk of wildfires. In February, State Farm General, which is California's largest insurance provider, said it received more than 8,700 claims and paid over $1 billion to customers in the wake of the wildfires. Citing a 'dire' financial situation, the company requested an emergency interim rate hike averaging 22% for homeowners from state officials, putting more pressure on California homeowners. Severe storms that created damaging tornadoes, winds and hail in the United States accounted for at least $33 billion in losses, according to estimates from Gallagher Re. The strongest storms hit the Midwest and South in mid-March, creating large tornadoes that raked through towns and hauled debris into the air. Gallagher Re estimated that the outbreak of storms between March 13 and March 16 totaled nearly $8 billion in insured losses. That's the fourth costliest storm outbreak for insurers on record, Gallagher Re reported. The rest of the world, meanwhile, experienced below-average insurance losses. Non-US insured losses were less than $10 billion, marking the second time since 2006 that the first half of a year fell short of $10 billion. The costliest non-US event of this year was April's earthquake in Myanmar and Thailand, where losses could top $1 billion once all of the claims are processed.
