A significant storm system is affecting various regions across the United States and New Zealand, bringing heavy rain, snow, and windy conditions. In New Zealand's South Island, heavy rain is forecast for Otago waterways with snowfall warnings on alpine highways, including the Crown Range Road and Milford Road, where snow accumulation and potential road closures are expected. In the U.S., winter weather advisories warn of up to 10 inches of snow in parts of Colorado and Wyoming, with hazardous travel conditions due to slick roads and freezing temperatures also affecting Idaho, Washington, and Montana. Maryland is under an Alert Day for stormy weather with expected storms continuing through Thursday. A large rainstorm is projected to drop between 0.75 to over 2 inches of rain in some areas by Wednesday, while Colorado faces gusty winds, showers, and storms with snow lines dropping to 9,000-10,000 feet, followed by warmer, sunnier weather later in the week.
