HASTINGS, Neb. (KSNB) - It’s been a stretch of absolutely beautiful autumn weather here this week. Such has not been the case in Florida and now along the Carolina coast as Hurricane Ian continues to churn north. While they see the negative direct impacts from this powerful tropical system, we are reaping the rewards of indirect impacts here in Nebraska.

Let’s first take a look at the genesis and typical path of tropical systems. Tropical systems start out as waves in the eastern Atlantic and if conditions are right, they can develop into a depression, tropical storm and then possibly a hurricane. Tropical waves follow the easterly trade winds just north of the equator. As the wave develops and becomes better organized it is guided by the winds around the Bermuda high centered over the Atlantic ocean. Typically tropical systems will travel around the periphery of the high and stay out over the ocean not affecting land. However, later in the season this high pressure fluctuates in strength and can push storms further west into the gulf then affecting the southeastern states. So, how does this affect us here seeing that Ian is almost 1400 miles away? most of the focus is placed on the eye of a hurricane which is roughly 20 to 40 mile wide. however, the entire circulation of a hurricane can measure 300 plus miles wide and reach heights of 50,000 feet. because of this, hurricanes can slow the progression of ridges and troughs moving across the united states. this has been the case with Ian slowing both the ridge of high pressure over the central u.s. and trailing trough over the pacific northwest. the extended stretch of wonderful early autumn weather, all thanks to Ian.
