Rising flood waters threatened communities across the Carolinas on Tuesday as storm Florence hit the U.S. Northeast with heavy rains and tornadoes after killing at least 33 people.

The White House said President Donald Trump would visit North Carolina on Wednesday. He has been criticized for his handling of Hurricane Maria, which devastate Puerto Rico last year, and more recently for disputing the official death toll of 3,000.

Widespread flooding has already reached roofs, turned highways into rivers and left thousands to be saved by rescue workers. Waterways are expected to keep rising on Tuesday in places like Fayetteville, North Carolina, a city of 200,000 in the southern part of the state, according to the National Weather Service (NWS).

At least 33 people have been killed since Florence came ashore as a hurricane on Friday, including 25 in North Carolina and six in South Carolina. One person was killed when at least 16 tornadoes developed from Florence on Monday in Virginia, where dozens of building were destroyed, the NWS reported.

The dead included a 1-year-old boy swept from his mother as they tried to escape their car amid floodwaters. The woman had driven around barricades to reach a closed road, the sheriff's office in Union County, near North Carolina's border with South Carolina, said on Facebook.

"Flooding is still going to be a concern into the weekend and into next week," NWS meteorologist Hal Austin said, noting there is a chance of rain for the region on Tuesday and Wednesday. "No more water, not even a drop, please."
