"Las Vegas Braces for Rain and Avalanche Risks as Super Bowl Crowds Arrive"

Las Vegas is facing rain threats and avalanche dangers as Super Bowl crowds arrive, with chances of scattered showers and heavy rain expected. The city has experienced colder temperatures than Minneapolis, the site of the 2018 Super Bowl. The influx of visitors for the event is anticipated to make it one of the busiest weekends on record for Las Vegas. Meanwhile, avalanches pose a potential risk north of the city, and the San Francisco 49ers have raised concerns about the practice field's condition.
