a 2022 study found that warming could bring a 114% increase in spring hailstorms which come from frontal systems. so, you know, curbing those emissions is going to be a key role. scientist looking to connect the dots as we see the frequency and severity in the coming months. we will see how that plays out. >> we know you will stay on top of it and let us know the latest. thank you. south lake tahoe and cross peak will soon be black banning plastic water balls bottles and cartons. this comes a month after truck he passed the measure, when tourist left behind 8000 pounds of trash on beaches, mostly plastic bottles. the town will also install more public water stations so tourists can fill reusable water bottles instead. you likely know that the tax date is less than three weeks away, and scammers are on
