United States: As a barrage of threats breaks out over the United States this week, creating hazards from coast to coast, it’s time to stay weather conscious. This week has everything, from “bomb cyclones” to extreme weather and nor’easters.
New evacuation orders have been issued for risky places near recent burn scars as a “bomb cyclone” speeds up a forecast of heavy rain throughout the West. Parts of Santa Barbara County, California, have been ordered to evacuate. The biggest snowfall will fall Sunday night into Monday, with the heaviest amounts falling at elevations above 5,000 feet. The Sierra Nevada mountain range is expected to get several feet of snow, making transportation practically impossible.
A temperature struggle was experienced in the mid-Mississippi Valley. Tornadoes are a serious threat in a specific area stretching from St. Louis to Springfield, Missouri. As warm, humid air from the south combines with more powerful cold fronts, fall typically experiences an uptick in activity.
Strong northeasterly winds, which is how a nor’easter gets its name, are expected to develop in the coming days. Flooding along the coast and heavy ris is also predicted in southern New England. According to some computer models, the region will receive more than 6 inches of rain.
