Tropical Storm Delta restrengthens

Tropical Storm Delta has proven to be resilient as it heads eastward across the Atlantic. The 10:00am EST advisory from the National Hurricane Center (NHC) shows Delta restrengthening to a tropical storm with winds of 50 mph and a central pressure of 990 mb. Delta has picked up speed and is now heading to the northeast at 26 mph.

Delta has developed a mid-level eye that is displaced to the east of the surface center of circulation. Satellite intensity estimates actually show Delta to be stronger than its latest advisory intensity. Should the eye and surface circulation develop closer together, it is likely that Delta will strengthen further.

However, increasing wind shear and cooler ocean temperatures are working to counteract the strengthening. Delta is expected to interact with a frontal boundary on Monday and transition to an extratropical storm. This should happen as gale force winds approach the Canary Islands, off the coast of Africa. The computer models are mostly all in agreement on this track and extratropical transition. However, Delta was originally expected to transition already.0:NHC Forecast track1:Infrared satellite image2:Computer model forecast tracks
