Southern Nevada could see a wetter winter, which may lead to localized flooding and disruptions. The Gulf Coast and Southeast U.S. are also expected to experience wetter conditions, increasing the risk of flooding in those areas. Conversely, northern U.S. regions and Canada may face drier and warmer conditions. The polar vortex's behavior could bring colder Arctic air further south, potentially causing wintry weather outbreaks in parts of the U.S. Residents in affected areas should prepare for potential weather-related challenges.
