Subtropical Alberto set to drench Florida on Sunday, Monday

On Friday, Alberto met the minimum requirements for earning a name, having reached sustained winds of 40 miles per hour.

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.

This incarnation of Alberto had the decency to wait and form after the official start of the hurricane season, but then wasted that goodwill by making landfall in Florida. Relatively dry weather is expected in SW Lower Michigan and very dry weather will continue from S. California east to Texas. All areas east of the Mississippi River across the Southeast have a chance to see flooding due to Alberto from this weekend into at least mid-week next week.

The storm is expected to bring heavy rain to the Yucatan Peninsula, western Cuba, Florida and the northeastern Gulf Coast throughout the weekend.

Subtropical systems can develop into fully tropical storms if they remain over warm water for several days. More than 6 inches of rain are in the forecast for parts of the Gulf Coast. It became a tropical storm that meandered off the cast coast of Georgia and SC. "In Florida, we know how unpredictable severe weather systems can be and while the Gulf Coast and Panhandle are expected to receive the largest impact from this storm, all Floridians should be prepared". Forecasters say heavy rains are likely across western Cuba, much of Florida and the northern Gulf Coast into early next week.

It's called a "subtropical storm" because it's something of a hybrid between a nontropical low-pressure area and a classic tropical storm. For more information, consult products from your local weather office.

The NHC expects the storm to make landfall late Monday or early Tuesday around the MS or Alabama coast, at which point its strength should decrease and it will become a tropical depression. The highest winds are also now away from the center.
