Subtropical Storm Alberto has formed. At 10:00 a.m. the National Hurricane Center named our first storm of the 2018 season. A storm is subtropical when it has both tropical and subtropical characteristics. This storm, like tropical systems, is not on a front and it has a closed circulation center. Unlike tropical systems, the winds are displaced 60 miles from the center, the most dense clouds are not on top of the center and very cold air exists above the center. In time, the system will likely evolve into a full-blown tropical system, but that will be slow to occur. The impacts from both subtropical and subtropical systems are identical, it’s just the basic physics that determine putting the ‘sub’ in front of tropical.
Here on the plateau, we won’t feel the impacts until Tuesday or Wednesday of next week, assuming the system continues to slowly track our way. I’ll keep you posted!
