Tropical Depression Strikes Indiana Of All Places, Bad Flooding Elsewhere

Tropical Depression Alberto still has a well defined tropical-like
circulation over Indiana on Wednesday. 

This morning, former subtropical Storm Alberto was still a tropical depression - in Indiana of all places.

Alberto has held together remarkably well as a tropical system. Usually, they transition pretty quickly to non-tropical storm systems or disturbances soon after moving inland.

Alberto will indeed become just a regular old inland weather system later today, but it's survivability into Indiana is pretty incredible.

Satellite photos from this morning show a well defined pinwheel Tropical Depression Alberto centered not far from Terre Haute, Indiana.

This is a big example of what's known as the "brown ocean."  The tropical disturbance can hold together becuase there is no influence from an upper level low that would disrupt the circulation. Also, there was plenty of low level and moisture from the ground to support the tropical system.

Remember, tropical systems depend on warm water to maintain their strength and integrity. When they go inland, that source of nutrition for tropical systems ends. Usually. Except in cases like this when there's nothing to disrupt them and there's plenty of atmospheric moisture to work with.

North Carolina Department of Transportation truck swept into a river
Tuesday. The two workers in the truck were rescued. 

While the actual circulation of Alberto is relatively small, it drew huge quantities of tropical, wet air into parts of the nation, causing or at least greatly contributing to some pretty horrible flash floods in some locations.

Western North Carolina was especially hard hit, with plenty of evacuations, water rescues, road closures and property damage.

Even the famed Biltmore Estate in Asheville was affected: The main entrance to the mansion and tourist attraction was blocked by floodwaters.

Ashville has had its wettest May on record.

Interstate 40 in McDowell County, North Carolina was closed due to landslides and flooding. Two North Carolina state highway workers had to be rescued from the flooding.

A flash flood emergency was also declared in parts of Alabama as well. Many roads are closed and people had to be rescued from at least one flooded home.

GERMANY FLOOD, TOO

Flash flooding seems to to be all the rage this week across much of the world. We had the Ellicott City, Maryland disaster on Sunday. Other flash floods struck parts of the Rocky Mountains. Areas of Great Britaina and particularly Germany have also been slammed by these floods.

Roads and buildings flooded, roofs collapsed and people were rescued, especially around the city of Wuppertal, Germany.
