Should the weather pattern become a full-fledged storm, with winds of at least 39 miles per hour, it would be named Tropical Storm Alberto.

A subtropical cyclone has characteristics of both tropical and extratropical cyclones, and tends to have a broader maximum wind radius than the cone of most tropical cyclones.

The National Hurricane Center said Thursday a mass of low pressure in the western Caribbean is becoming better defined and will likely become a subtropical or tropical depression by late Saturday.

In a 10 p.m. update, the National Hurricane Center said Alberto was 180 miles south-southwest of the western tip of Cuba, moving east at 5 mph. Strengthening is expected for the next 72 hours, according to the NHC.

The National Hurricane Center is monitoring a tropical system that will bring heavy rain to Florida and the Gulf Coast states by Memorial Day.

There were no direct deaths from Alberto as a tropical storm, but one drowning was reported in North Carolina after it became an extratropical storm. Impacts will extend far from the storm's disorganized center, having an impact on the northern Gulf coast and parts of Florida.

It's called a "subtropical storm" because it's something of a hybrid between a nontropical low-pressure area and a classic tropical storm.

Heavy rain will likely begin to affect the central Gulf Coast region and the southeastern US later this weekend and continue into early next week. At this time we should not see many severe storms, but there is always a chance for an isolated tornado as some of these bands of storms move through.

Because of this, the South Shore, Coastal Mississippi, St. Tammany Parish and Southern Tangipahoa Parish are under a flash flood watch.

Away from beaches, tomorrow's weather may be a bit wetter but not unusually different.

Subtropical Storm Alberto is the first storm of the Atlantic season, which doesn't officially start for another week.

There's also a strong threat of rip currents from Florida to Louisiana.
