Weather Channel meteorologist Chris Warren details the forecast along the East Coast as Andrea dumps inches of rain on the region.
Severe weather - and a risk of tornadoes - was expected in parts of the Plains and Midwest over the weekend, as post-tropical storm Andrea continued to cause flooding along much of the East Coast Saturday.
Michael Palmer, of weather.com, said Kansas City and Omaha, Nebraska, were among the cities expected to see strong storms on Saturday.
St. Louis was at risk of severe storms on Sunday, he added.
“A few storms are likely going to be severe, especially in Nebraska and Kansas on Saturday. The main threat will be large hail and damaging winds, but isolated tornadoes are possible,” he said.
Waves crash along the shore of Wrightsville Beach in Wilmington, N.C., as Tropical Storm Andrea makes it way up the east coast, bringing heavy rains and high winds.
Meanwhile, Andrea was bringing near gale-force winds, a risk of coastal flooding and heavy rain to the East Coast on Saturday.
The National Weather Service warned that the rain would be the storm’s “the main impact.”
“Some creeks and small rivers may rise out of their banks in the Mid-Atlantic and Northeast. Numerous flood warnings are in effect,” it said.
A notice issued by the weather service at 5 a.m. ET said coastal flooding was possible due to a storm surge in some areas from Long Island to New England.
“Post-tropical Andrea is expected to produce additional rainfall [of] up to 1 inch over parts of coastal New England. This will bring isolated storm total amounts to near 5 inches over parts of southern New England,” it said.
The heavy rain from the storm's outer bands was blamed by authorities in Virginia for a fatal accident on Interstate 77 in the state's western mountains.
William Petty, 57, of Lexington, S.C., died on Friday when a car in which he was a passenger hydroplaned while passing a tractor-trailer. He survived the crash, only to be killed moments later when the car was struck by second tractor-trailer, authorities told The Associated Press.
“Gale conditions are expected near portions of coastal Rhode Island and southeastern Massachusetts,” the 5 a.m. notice said.
At 5 a.m., the storm was about 35 miles west-southwest off the eastern tip of Long Island, the weather service said.
Andrea had maximum sustained winds of 45 mph, with higher gusts, and was moving northeast at 35 mph.
It was expected to turn toward the east on Saturday and Sunday. It is expected to move across Canada’s coast late Saturday through Sunday, the weather service said.
Flooding shut down highways across the tri-state, including a portion of the Saw Mill River Parkway in Westchester, NBCNewYork.com reported. It also slowed traffic significantly in places like the West Side Highway and the Northern State Parkway and Sunrise Highway on Long Island.
