New monitoring plan announced to learn more about Great Salt Lake dust, inform public
SALT LAKE CITY (ABC4) — In a news conference Tuesday morning, Great Salt Lake Commissioner Brian Steed gave updates on the state of the lake, and also announced an effort to better monitor the lake's dust.
Currently, Steed shared that the lake is lower than it's preferred to be, however, the lake salinity, which is how much salt is dissolved into the water, is at healthy levels. Salinity can be a concern if it gets too high, which happens when the water is too shallow.
'It's something we are also monitoring quite carefully because if we have a hot, dry summer with low precipitation, that can drop that into really scary levels,' he said.

Additionally, Tim Davis, the executive director of the Department of Environmental Quality, described a comprehensive plan for monitoring dust at the Great Salt Lake.
That plan includes 19 new monitors, which are set to be around communities that could be impacted by the Great Salt Lake, as well as other potential dust sources, including near the West Desert and the Nevada border. There will be two types — continuous monitors, which will collect data all the time, and filter monitors, which will capture particles to be analyzed following a dust event.
Davis said this is to be able to differentiate sources of dust, what they're made up of, and inform the public.
'[We want to] develop tools to give people a heads up when a potential dust storm could be coming, and so people who are sensitive, for example, if they have asthma, that they can take steps to protect themselves,' he said.
The first step for this, he shared, is developing a dust network. Davis said it can take some time to put in the monitors, as they're meant to be permanent. However, the hope is the project can get its start in July.
'I'll just say how excited I am for this project. It's one of the major data gaps we've had, honestly, on Great Salt Lake management to see how much dust is coming off the exposed lake bed and what's in that dust. Trying to figure that out is going to be a key question going forward. And so I really appreciate Director Davis for his dedication to figuring out better data and to have that information available for all of us when we go ahead and make these choices,' Steed said.
Davis shared that they're planning to gather quantitative data related to dust that will eventually be used in the same system that warns Utahns about unhealthy air quality days.
'The first thing we need to do is just gather the data,' he said. '… We do have some data already on just those potential sources, but we need better data. We need more information about it in order to really characterize it and give people an idea of if there is a risk, what is the potential risks from different sources?'

'Protect yourself': With sweltering heat wave on way for region, emergency officials urge safety
JOHNSTOWN, Pa. – A wave of extreme heat will blanket much of the eastern U.S. starting Sunday. The heat wave will bring temperatures as high as 93 degrees Fahrenheit through Tuesday in Johnstown, and just a few degrees less than that in Somerset, according to National Weather Service forecasts. Factoring in humidity and the region's recent wet, chilly weather, it will feel even hotter, NWS meteorologist Michael Colbert said. That could create trouble if people aren't careful in western Pennsylvania, he said. 'Certainly we're not acclimated to this heat, given how wet it has been,' Colbert said. The weather will likely mean plenty of sunshine, but also dangerous heat and UV radiation levels, he added. More than 700 people die from heat-related illnesses every year, according to the Centers for Disease Control and Prevention. Safety tips Local emergency officials urged residents to avoid the worst of the heat – and to take precautions to stay safe through the sweltering stretch. 'Knowing what to do to protect yourself and loved ones from extreme heat can save lives,' said Jorge Martinez, CEO of the American Red Cross of Greater Pennsylvania. In a telephone interview Friday, Somerset County Emergency Management Director Joel Landis echoed Martinez's message. He said the main thing people can do is stay indoors and avoid too much sun exposure. People who don't have adequate means to keep their homes cool, such as air conditioning, should find somewhere that does, Landis advised. Somerset County will use its six senior centers as public 'cooling centers' daily while high temperatures persist. They will operate from 9 a.m. to 2 p.m. Monday through Friday. Cambria County's nine senior activities centers will also be open to the public if needed next week, Cambria County Emergency Management Agency Director Tom Davis said. 'If anyone needs to get out of the heat, regardless of their age ... they can go to our senior centers,' Davis said. Davis and Landis said emergency management officials will be monitoring the situation as temperatures rise and needs potentially become apparent. If additional cooling centers need to be opened, steps will be taken, Davis said. For those who do go outdoors, find shady areas or cool off at a pool – but limit periods of outdoor exposure, Colbert advised. He reminded people to apply sunscreen regularly and to wear a hat and light, loose, breathable clothing. The American Red Cross advises people to drink at least a glass of water every hour to stay hydrated. 'If outages occur' Davis said communication will also be ongoing with Cambria County's hospitals, which may also be needed if dehydration and heat exhaustion cases become an issue. Landis said Somerset County emergency management officials will be monitoring locations that could need support if power outages occur, such as personal care homes or hospitals. 'If outages occur, we'll be ready to assist those facilities with whatever resources we have,' Landis said. The key message to the region's communities was for people to look after one another. Check in on neighbors and loved ones who might be susceptible to the heat, Landis and Davis advised. Red Cross officials agreed. 'We're asking everyone to check on friends and neighbors, especially older adults, people with chronic conditions, outdoor workers and athletes,' Martinez said. 'You could make all the difference by sending a text, making a call or knocking on their door.' People were also reminded to never leave children or pets alone in parked cars, which can become extremely hot in a short amount of time. Colbert said people should also avoid over-exerting themselves, and urged people to consider avoiding the hottest period of the day to tackle outdoor projects. 'If any community needs arise, call 911,' Davis said. Colbert said the temperatures will surge due to an expansive high-pressure system that will trap hot air over the eastern U.S. It will bring drier air and a likely break from the recent stormy system, but also potentially record-setting temperatures, forecasters added. Colbert said conditions will likely improve after Wednesday as chances for cooler conditions and rain increase.

Critical fire weather conditions for southern Utah today as hot and windy weather continues
SALT LAKE CITY (ABC 4) – Happy Monday, Utah! After high heat over the weekend, our weather pattern begins to shift Monday as a weak tough in the Pacific Northwest moves inland. That change will flatten the ridge that's been keeping things toasty, especially in northern Utah. As a result, northern areas can expect a slight cooldown compared to Sunday, while southern Utah holds steady with hot, dry conditions. With the trough approaching and winds picking up, we'll see gustier conditions Monday afternoon and evening—most notably across southern and eastern Utah. That will stir up fire weather concerns, especially with how dry the air remains. Red Flag Warnings are in effect from noon to midnight today for the southern half of the state due to the increase in winds. This means that existing fires will spread rapidly in addition to any new fires that start. Wind gusts up to 35 mph are expected with sustained winds of 10-25 mph. Late Monday night, a weak front will move through the state. It looks to be mostly dry since moisture is very limited. Still, a couple of isolated sprinkles can't be ruled out for northern Utah, but most of us will stay dry. By Tuesday morning, that front will have swept through most of Utah and will help drop temperatures 5-10 degrees from Monday, with the most noticeable change across northern Utah. Winds will shift more northwesterly behind the front, and while they'll still be breezy, they won't be as gusty as Monday. Midweek, high pressure over the Southwest will start sliding westward, keeping things dry but allowing for a gradual warm-up Wednesday. Winds will stay relatively light, and the pattern will start to resemble what we saw earlier in the week. Thursday brings another round of very hot, very dry weather. Southwest winds will increase ahead of another trough diving into the Pacific Northwest. Relative humidity will drop into the single digits and teens, and temperatures could flirt with record highs—especially in the valleys. Salt Lake City could hit 102°, which would break the record for that day. Heading into Friday and Saturday, the next system moves closer. Winds are expected to ramp up again, and a weak cold front could start pushing into northern Utah by Saturday. That front may bring some relief from the heat up north, but to the south, gusty winds and bone-dry air will keep fire weather concerns front and center. Stay tuned.

Aerial firefighting crews ready for southern Utah's peak fire season
CEDAR CITY, Utah (ABC4) — As southern Utah heads into the peak of fire season, federal and state officials share that aerial resources and public safety plans are ready to deploy. Crews from across the west met at the Cedar City Air Tanker Base on Thursday to talk strategy ahead of what could be an above-average fire season. With fires popping up in Nevada and Arizona already, they say these tankers might not be sitting there for long. The base is one of the busiest in the region, supporting firefighting efforts across southern Utah, northern Arizona and eastern Nevada. While the season has been off to a slow start, crews said that could change in a flash. Origins of Yellow Lake Fire revealed 'We haven't had much of a season yet — it usually starts down south and moves its way north, so there's plenty of resources to go around,' said Courtney Christensen with the Bureau of Land Management Color Country District. When fire conditions escalate, so does the need for aircraft. That's why aerial support is critical to getting fires under control before they grow. They aren't assigned at random. As fires ignite across the west, they are moved where they're needed most. 'We may have a fire here in Cedar, but the priority might be shifted to somewhere else because it's brand new and threatening homes, communities, power lines, infrastructure, or major watersheds,' said Lindsey Fonger with Zion National Park Fire Management. Forest thinning may lead to more wildfire danger Fire officials said that this year's outlook looks dry, and crews are expecting conditions to ramp up fast in the coming weeks. But as much as officials are focused on response, they're also asking the public to do their part to prevent fires in the first place. The one growing threat responders face is drones. 'Drones in the wildland fire area sometimes force fire managers to suspend aerial resources, which ultimately could turn into those wildland fires becoming larger and more dangerous because we don't have the aircraft to fight those fires,' said Brandon Davis with BLM Arizona Strip District Fire Management. Officials ultimately warn that even one spark, under the right conditions, can be enough to trigger a wildfire.
