Tropical Storm Gabrielle appears to have intensified slightly over the last several hours, as upper-level shear has lessened and the storm remains over the warm waters of the Gulf Stream. Maximum sustained winds are still estimated at 35 knots as of the 2:00 am EDT advisory, but Gabrielle will likely intensify before passing over the North Carolina Outer Banks early tomorrow afternoon. The current NHC forecast indicates 45 knot sustained winds with Gabrielle at the time of landfall. The IR loop as of 2:00 am EDT is displayed below:
The likely center of circulation and outer bands of Gabrielle are well-defined on Morehead City, NC radar, with occasional supercells developing within these bands and near the center. Heavy rain, isolated tornadoes, and gusty winds will be the main threat as the tropical storm comes ashore, with a 2-3 foot storm surge causing minor beach erosion.
As is normally the case with recurving tropical cyclones at this latitude, Gabrielle will make a quick transition to an extratropical cyclone as it merges with the jet stream and accelerates to the northeast along the Gulf Stream. This storm will likely become an intense mid-latitude cyclone over the North Atlantic, and could cause heavy rain and strong winds several days from now somewhere in the UK.
