September 2008 Carolinas storm

The September 2008 Carolinas storm was a strong extratropical cyclone which affected areas of the United States Eastern coast.

Meteorological history
Beginning on September 21, 2008, a strong plume of moisture began to stream out of the Gulf of Mexico along a frontal boundary which stretched into the open Atlantic Ocean. At 1300 UTC the following day, a large concentration of thunderstorm activity developed in the Apalachicola Bay and quickly broke into two segments. The weaker component made landfall near Beverley Hills, Florida, at 1900 UTC later that day, while the stronger of the two progressed southeast before reaching Fort Myers, Florida, at 2300 UTC.

The stronger component later broke apart into several clusters of storms which moved eastward across southern Florida, before weakening after reaching the Atlantic Ocean and dissipating at the Bahamas by 0800 UTC on September 23. However, the weaker system maintained its intensity as it moved across the Florida Panhandle and into the Atlantic. The system coalesced with additional frontal storms over the Atlantic and gained intensity. On 1600 UTC, the newly developed disturbance began to show signs of cyclonic rotation. A low pressure area was first identified with the cyclone at 2200 UTC later that day. At the time, the extratropical storm had a pressure of 1013 mbar (hPa; 29.91 inHg).

The extratropical storm continued to move towards the north-northeast along with the frontal boundary until about 0600 UTC on September 24, when it split from the front and began moving towards the coast. As a result, the storm intensified, and a new cluster of systems coalesced near the low pressure's center.
