The so-called nor’easter is bringing “dangerous coastal flooding and beach conditions, strong winds and heavy rainfall” to areas including New York City and Boston on Saturday, the US National Weather Service (NWS) said.

States of emergency have been declared in New York and New Jersey, both of which faced a coastal deluge in some areas. Rain and strong winds are forecast from Virginia to Maine.

Ed Sheeran’s much-awaited Boston concert was among events called off due to the weather.

The Federal Aviation Administration recommended air passengers check with airlines about their flight status. More than 2,400 flights have been delayed and another 1,199 grounded, according to FlightAware.

Saturday’s full moon is projected to worsen coastal flooding. Streets and homes were inundated with floodwater in the coastal New Jersey communities of Surf City and Manasquan on Saturday.

“I urge all New Jerseyans to take this storm seriously, stay alert and follow local guidance,” Governor Mikie Sherrill said.

NWS said in its alert: “Prepare immediately for significant inundation in low-lying areas near the shore, including roads underwater and impacts to homes and businesses.”

In New York, officials are warning of wind gusts of up to 55mph (86km/h) throughout the weekend, leading to downed trees and power lines

He told reporters at the White House that Tehran “want to make a deal where they open the Strait immediately because they’re losing so badly”.

In a post on Telegram, Iran’s Foreign Minister Abbas Araghchi acknowledged Trump’s comments, but said Tehran would wait for an official response from mediators.

On Friday, Araghchi had told reporters at the UN in New York that an agreement could be reached “if the necessary conditions are met” and that these were contained in a memorandum of understanding (MOU) signed by the two countries in June.

The vital waterway through which around a fifth of the world’s gas and oil supply usually flows has been effectively closed since the outbreak of war in February.

“I’m rejecting their deal,” Trump said on Saturday, adding that the US already had “total control” of the strait, with “massive amounts of oil” passing through it.

“They want to make a deal, and I think that’s fine. I like making a deal, too. But that deal would not be acceptable,” he added.

Araghchi wrote that Trump “has made many good statements, as well as many contradictory ones, which unfortunately we hear frequently.”
