When subtropical systems are above water temperatures over 80 degrees, it is common for upper-level winds to relax. This is what is expected over the next few days.
The warmer water temperatures of the Gulf of Mexico will also tend to warm the core of Alberto's low-pressure circulation through this weekend which should, when combined with lessening upper-level winds, allow Alberto to become a conventional tropical storm. When an area of low pressure forms over waters with sea-surface temperatures of at least 70 degrees, a subtropical low can form.
This is due to the core of the storm becoming warm, deriving some of its energy from latent heat, or energy released when water vapor that evaporated from the warm water is condensed into liquid. A subtropical storm exhibits features of both tropical and non-tropical systems.
This includes no cold or warm fronts, a broad wind field and thunderstorms removed some distance from the center of circulation. This is common with subtropical storms.
