It’s a swirl on satellite that looks like a hurricane. But it’s not. The damage it has caused in the Carolinas though, especially as it relates to inland and coastal flooding, resembles what is often left behind from a hurricane. Thankfully it won’t be nearly as dramatic, but the back edge of this weather system will swing through North Florida Monday resulting in clouds, spotty showers and cool temperatures. Any rain that falls should be brief and light in nature, with highest chances in the afternoon hours. Thanks to some extensive cloud cover for most of the day, high temperatures will likely be a bit below normal for early October, falling short of 80° in many areas. An explanation of the large swirl over Florida is just below your hour-by-hour forecast.
The Tale of Two Swirls
Even though it appeared larger than Hurricane Joaquin on satellite Monday morning, the weather system over Florida is drastically different. A hurricane is a tightly wound area of surface low pressure that forms over warm ocean water and can produce destructive winds or a deadly storm surge. The storm system that caused the historic flooding in the Carolina’s typically develops over land, is accompanied by colder air and lower pressure aloft, and is usually much weaker. However, the interaction between these two features was particularly unique and resulted in a steady stream of tropical moisture that lasted for days in South and North Carolina. Some areas just southeast of Columbia, SC received more than fifteen inches of rain in just two days!
