Low pressure center strengthening into tropical system

A low pressure situated in the middle of the North Atlantic Ocean seems to be developing tropical characteristics and could become a tropical storm at any time. If the system is upgraded, it would become Tropical Storm Delta, the twenty-eighth Atlantic tropical cyclone of the 2005 season.

Visible satellite imagery is clearly depicting a strong circulation with well defined banding features. The visible shot actually looks very much like a typical hybrid or late season tropical storm.

The infrared imagery is where its non-tropical characteristics show up. Right now the low is lacking any deep convection. As soon as the low develops substatial deep convection and the associated outflow to allow the convection to sustain itself, look for the National Hurricane Center to issue advisories for Delta.
