Hurricane Dorian made landfall this morning (Sept. 6) on the barrier islands of North Carolina's Cape Hatteras, carrying with it what the National Hurricane Center (NHC) called a "life-threatening storm surge and dangerous winds," as well as the risk of flash flooding.
The large storm's winds have lessened significantly since it brutalized the Bahamas last weekend as one of the most powerful hurricanes ever measured. But weather stations on the Carolina coast recorded serious sustained winds of 74 mph (119 km/h) and gusts up to 92 mph (148 km/h), according to an 11 a.m. EST advisory from the NHC.

Water, not wind, remains the most serious danger from the storm. The NHC has already reported a major storm surge, over 5 feet (1.5 meters), in North Carolina. The agency shared alarming images of the floodwaters online.

The storm will impact the North Carolina coast, southeastern Virginia and Chesapeake Bay "for the next several hours," according to the NHC, with the most severe flash flood risks in North Carolina and far-southeastern Virginia.
The NHC issued tropical storm warnings for parts of Delaware and coastal Massachusetts and Maine, which may face the outer bands of the storm Saturday as it continues to power its way north through the Atlantic.
The next place to deal with hurricane-force winds from Dorian's core is Canada's Nova Scotia, where the eye should arrive by late Saturday. The NHC also issued warnings for Prince Edward Island and Newfoundland.
A large region of Canada's maritime region may face significant rainfall, flood risk and wind, according to the Canadian Hurricane Centre (CHC). The CHC's forecast warns of dangerous storm surge along the Atlantic coasts of Nova Scotia, Prince Edward Island and Newfoundland, noting that the storm could remain a hurricane as it passes north through Newfoundland.
If you live in one of the Canadian provinces threatened by the coming storm, the time to start preparing is now, according to the NHC.
