Heavy rain and floods are hitting parts of the US east coast, causing flight cancellations and leaving drivers stranded in cities including New York.

A total of almost 50 million people in the US are under flood watches, and states of emergency have been declared in New Jersey and New York City, with state workers being sent home early.

Airports in NYC, New Jersey and Philadelphia all reported significant flight delays and cancellations as the severe weather arrived on Thursday.

Flights leaving all three of New York’s largest airports are delayed, and all inbound flights are being held until conditions improve, Sky’s US partner NBC News reports.

Planes have also been grounded at airports in Washington DC and Baltimore, Maryland.

A major highway in the New York borough of Queens was closed in both directions, with traffic cameras and social media posts showing vehicles stranded in deep water.

Officials in New York have warned that heavy rain could also flood parts of the subway and basements.

People living in basements have been urged to move to higher floors and New Yorkers are being asked to avoid travel until Friday afternoon.

The commuter rail system into suburban Long Island suspended trains on one of its busiest lines as officials pleaded with people to stay at home.

“Stay home this evening unless it’s absolutely necessary for you to go out,” Nassau County executive Bruce Blakeman told Long Island residents.

Tornado warnings were also in place in New Jersey, and while no twisters were reported, more than 6,000 electricity customers have been left without power.

In some parts of Pennsylvania, National Weather Service warnings said there could be up to three inches of rain in just one hour, and a downpour flooded the streets of Reading.

Up to four inches of rain have fallen in parts of Maryland and Washington DC, and the heavy rain is continuing, NBC reports.

Flood and severe thunderstorm watches are in effect for parts of Pennsylvania until Friday, with four to six inches of rain possible in some areas.

The Federal Reserve has defied calls from US President Donald Trump for a cut to the interest rate by leaving it unchanged.

The decision means it has an effective rate of 4.3%, where it has remained after the central bank, known as the Fed, reduced it three times last year.

“We’re keeping the rates high, and it’s hurting people from buying houses,” Mr Trump told reporters. “All because of the Fed.”

Mr Trump has repeatedly been asked whether he would fire Fed chair Jerome Powell if he failed to heed his demand to cut the rate.

In June, the US president labelled Mr Powell a “stupid person” after the Fed decided not to change rates. Then less than two weeks later, in a further attack, he said the Fed’s chair should “ashamed” and would “love” him to resign.

The US president has spent months verbally attacking Mr Powell.

There were clear tensions between the pair last Thursday as they toured the Federal Reserve in Washington DC, which is undergoing renovations.

When taking questions, Mr Trump said: “I’d love him to lower interest rates,” then laughed and slapped Powell’s arm.

The US president also challenged him, in front of reporters, about an alleged overspend on the renovations and produced paperwork to prove his point. Mr Powell shook his head as Trump made the claim.

When Mr Trump was asked what he would do as a real estate mogul if this happened to one of his projects, he said he’d fire his project manager – seemingly in reference to Mr Powell.

Unlike the UK, the US interest rate is a range to guide lenders rather than a single percentage.

The Fed has expressed concern about the impact of Mr Trump’s signature economic policy of implementing new tariffs, taxes on imports to the US.

On Wednesday, the president said he was still negotiating with India on trade after announcing the US will impose a 25% tariff on goods imported from the country from Friday.

Mr Trump also signed an executive order on Wednesday implementing an additional 40% tariff on Brazil, bringing the total tariff amount to 50%, excluding certain products, including oil and precious metals.

The committee which sets rates voted 9 to 2 to keep the benchmark rate steady, the two dissenters were appointees of President Trump who believe monetary policy is too tight.

In a policy statement to explain their decision, the Federal Reserve said that “uncertainty about the economic outlook remains elevated” but growth “moderated in the first half of the year,” possibly bolstering the case to lower rates at a future meeting.

Nathan Thooft, chief investment officer at Manulife Investment Management, described the rate decision as a “kind of a nothing burger” and it was “widely expected”.

Tony Welch, chief investment officer at SignatureFD, agreed that it was “broadly as expected”. He added: “That explains why you’re not seeing a lot of movement in the market right now because there’s nothing that’s surprising.”

A powerful 8.8-magnitude earthquake has struck off Russia’s far eastern Kamchatka Peninsula, causing a tsunami.

A tsunami of up to four metres (13 feet) was recorded in Kamchatka Peninsula, leading to evacuations and damaging buildings, officials said.

Tsunami warnings have been issued for Japan, the Philippines, Hawaii and parts of Alaska in the US.

The Honolulu Department of Emergency Management in Hawaii has called for the evacuation of some coastal areas, writing on X: “Take Action! Destructive tsunami waves expected.”

The first waves in Hawaii are expected to hit at 7pm local time (6am UK time).

The Pacific Tsunami Warning Center has said waves of one to three meters (three to 10 feet) above tide level were possible along some coastal areas of Hawaii, Chile, Japan and the Solomon Islands.

Kamchatka Governor Vladimir Solodov had earlier said: “Today’s earthquake was serious and the strongest in decades of tremors.”

Several people in the region sought medical assistance following the quake, Oleg Melnikov, regional health minister told Russia’s Tass state news agency.

“Unfortunately, there are some people injured during the seismic event. Some were hurt while running outside, and one patient jumped out of a window. A woman was also injured inside the new airport terminal,” Mr Melnikov said.

Russia’s Tass news agency reported from the biggest city nearby, Petropavlovsk-Kamchatsky, that many people ran out into the street, while cabinets toppled inside homes, mirrors were broken, cars swayed on roads and balconies on buildings shook noticeably.

Power outages and mobile phone service failures were also reported in the capital of the Kamchatka region.

The first tsunami wave hit the coastal area of Severo-Kurilsk, the main settlement on Russia’s Kuril Islands in the Pacific, according to the local governor Valery Limarenko.

He said residents were safe and staying on high ground until the threat of a repeat wave was gone.

A regional branch of Russia’s geophysical service has said that “significant, noticeable” aftershocks with magnitudes of up to 7.5 after expected to continue for at least another month.

Japan issued a tsunami warning, saying it expects waves as high as three metres to arrive along large coastal areas along the Pacific Ocean.

It has ordered the evacuation of some areas.

The National Tsunami Warning Center, based in Alaska, issued a tsunami warning for parts of the Alaska Aleutian Islands.

A tsunami warning also was extended to the US state of Hawaii, with the National Weather Service’s Pacific Tsunami Warning Center saying a tsunami from the quake had been generated that could cause damage along the coastlines of all the Hawaiian islands.

A tsunami “watch” was issued for portions of the West Coast, including California, Oregon, and Washington.

The US Geological Survey said the earthquake was shallow at a depth of 19.3 km (12 miles), and was centred about 125 km (80 miles) east-southeast of Petropavlovsk-Kamchatsky, a city of 165,000 along the coast of Avacha Bay. It revised the magnitude up twice from 8.0 and 8.7 to 8.8 earlier.

Meanwhile, New Zealand’s disaster management agency has warned that the country’s coastal areas could expect “strong and unusual currents and unpredictable surges at the shore”.

In a national advisory alert, Civil Defence New Zealand said there was no immediate need to evacuate but said citizens should stay away from beaches and shore areas.
