Chloe Koast
Chloe Koast is a two-time Emmy Award-winning journalist, meteorologist and morning anchor at News 3 Las Vegas, focused on desert weather and environmental conditions as they play out in real time. Her coverage centers on translating heat, storms, wind and air quality into straightforward guidance, and tying those conditions to safety, infrastructure and daily life across the region she covers. She combines forecast-driven reporting with live interviews and on-air conversations, making environmental and weather risk a consistent thread through both her newscast and her ARC Las Vegas morning show.
Desert heat, storms and fire risk
Koast’s core reporting revolves around high-impact weather in the desert, especially extreme heat events and wind-driven fire danger. In her piece on an unprecedented heat wave, she walks viewers and readers through record-challenging temperatures, explains how far conditions deviate from seasonal norms, and highlights official warnings issued for the week ahead.
Her coverage of red flag warnings for Southern Nevada details the timing of the alert, the specific combination of gusty winds and dry air driving fire risk, and the geography covered by the warning, keeping the focus on practical risk rather than abstract climate talk.
Regular forecast stories track heat streaks, rising temperatures through holiday weekends and the evolution of storm chances, pairing simple descriptions of highs and lows with short explanations of the systems responsible. In pieces such as her “Calm before the storm” coverage of powerful winds, she links day-to-day conditions to incoming changes, outlining when winds intensify and which communities will feel the strongest impact.
Air quality, pollen and everyday health context
Koast consistently adds environmental and health context to her forecasts through air quality and pollen reporting. In her heat wave coverage, she includes current air quality ratings and breaks out specific tree, grass and weed pollens driving “very high” and “high” readings, effectively connecting the forecast to respiratory and allergy concerns.
Her wind-focused reporting also notes when pollen has “spiked,” again listing common pollens by type so that people can see how changing conditions might affect them.
Even when writing about the end of a prolonged dry streak, she folds in air quality assessments alongside rainfall amounts, putting pollution metrics next to precipitation data rather than treating them as a separate topic. This repeated pairing of weather, air quality and pollen makes her environmental coverage more granular than a generic forecast and shows a clear interest in how atmospheric conditions intersect with public health.
Community conversations and local policy on ARC Las Vegas
Beyond forecast stories, Koast uses ARC Las Vegas to host conversations where environmental and urban issues meet local policy. In a segment on her neighborhood’s homeless crisis, she and her co-anchor bring a county commissioner onto the show at a vacant lot that has become a hotspot for unhoused residents, using the location itself to frame discussion of what measures are being taken and how residents can flag emerging issues.
She sits down with the same commissioner to unpack new rules for street vendors, turning a regulatory change into an accessible explanation of what’s next for vendors and neighborhoods. Her topic page includes a piece on how to reduce political mailers, reflecting an interest in the everyday civic environment as people experience it in their homes and mailboxes. In another widely discussed segment, Koast recounts being trapped in a California travel nightmare after a major Interstate closure, emphasizing the human impact of infrastructure failures, heat, limited fuel and basic needs on stranded drivers.
These conversations and first-person reports show her using her platform to connect policy decisions and infrastructure problems to the lived realities of people navigating extreme conditions and urban pressures.
Service, consumer and lifestyle reporting
Koast’s reporting also includes service-oriented and lifestyle segments that sit adjacent to her environment and safety focus. She interviews a regional manager from Phantom Fireworks about “safe and sane” fireworks rules ahead of the Fourth of July, positioning the conversation around what is allowed, what is safe and how to reduce risk during a high-fire-danger holiday.
Her coverage of Making Strides Against Breast Cancer features her role as emcee as well as the event’s return, highlighting local participation and community support around a major health cause.
Topic-page clips show her taking part in a “barista for a day” challenge at Virgin Hotels, leaning into light lifestyle content while still keeping the framing as a station-branded segment. She has also reported on prioritizing items and choice budgeting for school shopping, using a back-to-school context to walk through how families can structure spending decisions when costs add up.[anchor] Her author bio notes that she regularly spotlights local community events and visits schools to talk about weather, reading and higher education, which fits with the community-facing tone of these segments. Taken together, this service and lifestyle work shows a reporter who is comfortable shifting from hard weather and risk coverage into practical, everyday guidance, while still keeping public safety and community engagement close to the center of her beat.
Before joining News 3 Las Vegas, Koast worked as a weather anchor and reporter at other regional television stations, building experience covering severe storms, wildfires and breaking news across different markets. That background, combined with her current dual role as meteorologist and anchor, underpins a style that treats the environment not just as a forecast but as a constant, evolving factor in transport, health, policy and community life.
