Subtropical Storm Melissa forms in the Atlantic
Subtropical Storm Melissa, the 13th named storm of the 2013 Atlantic hurricane season, formed today about 700 miles east of Bermuda.
Forecasters expect Melissa — which may reach tropical storm status by Tuesday — to head generally in a northeasterly direction before turning more northerly later in the week.
The storm is not expected to reach hurricane status or threaten land, according to a five-day track published by the National Hurricane Center.
What exactly is a subtropical storm? The National Hurricane Center defines it as follows:
A non-frontal low pressure system that has characteristics of both tropical and extratropical cyclones. The most common type is an upper-level cold low with circulation extending to the surface layer and maximum sustained winds generally occurring at a radius of about 100 miles or more from the center. In comparison to tropical cyclones, such systems have a relatively broad zone of maximum winds that is located farther from the center, and typically have a less symmetric wind field and distribution of convection.
Hurricane season ends November 30.
