Tropical Storm Danny, which formed in the Atlantic on Wednesday, has maximum sustained winds of 60 mph today, up from 50 mph yesterday. It is expected to continue strengthening—possibly reaching Category 1 hurricane status—as it tracks north. The National Hurricane Center’s (NHC) five-day forecast as of 11 am EDT shows Danny moving on a course that may see it pass near the Carolinas late tomorrow and New England (Connecticut, Rhode Island and Massachusetts) on Saturday, when it is forecast to reach hurricane strength. While the NHC’s most likely forecast track keeps Danny offshore of New England, some dynamical models suggest a possible landfall on Massachusetts’ Cape Cod some time on Saturday. Late on Saturday, or early Sunday morning, Danny is expected to make a landfall in Nova Scotia, Canada, most likely as a tropical storm. Danny is currently 320 miles northeast of Nassau, Bahamas, and 550 miles south-southeast of Cape Hatteras, North Carolina. Its tropical storm-force winds extend outward up to 205 miles. The storm is moving northwest at 13 mph, but the NHC forecasts Danny will veer north and pick up speed tomorrow, reaching wind speeds of 75 mph. This would make it a very weak Category 1 hurricane. By Friday night, Danny will be in the vicinity of a low pressure trough that may prevent the storm from weakening as quickly as might otherwise be expected in the presence of the high wind shear expected along the U.S. coast this weekend. The AIR tropical cyclone team is continuing to monitor Tropical Storm Danny’s progress and will provide new information as warranted by events.
