Intense rain swamped the US East Coast on Monday, setting off dangerous flash flooding from Virginia to New York that killed at least two people and prompted dozens of rescues as water overwhelmed roads and subways.
Monday (local time) saw the most flash flood warnings ever issued in a single July day, with nearly 100 issued, primarily across the Mid-Atlantic and Northeast. Flooding was reported near Newark, New Jersey, New York City, northern Virginia and southern Maryland, according to the National Weather Service.
Two people died in Plainfield, New Jersey, after a vehicle was swept away by floodwater, Union County spokesperson Kelly Martins told CNN in a statement.
Authorities responded to reports of the submerged vehicle around 2:30am on Tuesday, Martins said. Union County police assisted with 19 water rescues and the county's regional communications centre received over 1200 emergency calls in just two hours during the height of the storm, she added. The area saw rainfall totals between 3 to 5 inches.
More rain is expected on Tuesday across the southern Appalachians and Mid-Atlantic. Storms in the East on Tuesday will be more scattered and less intense than Monday's, but they could still bring some heavy rain wherever they bubble up - and with the ground already soaked in these areas, as little as an inch of additional rain could set off more flooding.
Showers on Monday dominated the Northeast by the latter half of the day and the heaviest storms arrived by early evening, threatening rush hour commuters.
New Jersey Gov Phil Murphy declared a state of emergency due to the flooding on Monday night, warning residents to "remain off the roads unless absolutely necessary". The governor on Tuesday noted some roadways remained closed as crews worked to "clear debris, make emergency road repairs, and remove abandoned cars caught in last night's flooding".
New York City experienced its second wettest hour on record Monday night after a little over two inches (51mm) fell between 7pm and 8pm local time. This record is only beaten by the approximately three-and-a-half inches (89mm) of rain recorded during
the remnants of Hurricane Ida in 2021
. New York City received a total of 2.64 inches (67mm) of rain, shattering its previous record for 14 July rainfall set in 1908.
Videos on social media showed water gushing onto platforms in New York's subway and flowing through subway cars as passengers crouched on seats. At least one subway station was flooded by the deluge, according to a spokesperson with the Metropolitan Transit Authority. Several trains were also suspended, delayed or rerouted due to the flooding,
according to MTA's website
.
Metro-North Railroad and New Jersey Transit said on their X accounts that they were also experiencing delays due to flooding.
Several airports in the New York City area
issued temporary ground stops and delays
on Monday evening, according to the Federal Aviation Administration, and impacts were also reported at Ronald Reagan Washington National Airport and Boston Logan International Airport.
In New Jersey and Pennsylvania, cars struggled to navigate flooded streets, according to videos on social media, with multiple people needing to be assisted, according to authorities.
North Plainfield, New Jersey, Mayor Lawrence La Ronde
told CNN affiliate WABC
emergency crews rescued people from at least 30 homes, after streets became completely flooded and were impassable.
In Lancaster County, Pennsylvania, 16 water rescues were reported in Mount Joy Township Monday afternoon, according to the Mount Joy Fire Department.
"Starting around 2:00pm, intense rainfall dropped over seven inches (178mm) of rain in less than five hours, overwhelming stormwater infrastructure and inundating portions of the borough," the fire department said in a Facebook post. "The west end of town was hardest hit, with reports of over five feet of water (1.5m) in some homes."
In Virginia, the National Weather Service issued a flash flood emergency - the most severe flood warning - late Monday into early Tuesday for the cities of Petersburg and Colonial Heights, where upwards of two to three inches (76mm) of rain fell in less than two hours.
One gauge near downtown Petersburg showed the Lieutenant Run Creek rose more than 10 feet (3.04m) in two hours between 10pm and midnight Monday, reaching major flood stage. Water levels have since dropped.
"Many neighbourhoods are underwater," with downed trees and power lines, Petersburg Fire Rescue & Emergency Services said in a Facebook post Tuesday morning. Crews were working through the night, "pulling people from flooded cars, responding to medical emergencies, clearing downed trees, and still answering every call for help," the department said.
More showers are expected to develop in the Mid-Atlantic and Southeast Tuesday afternoon, with a band of strong storms to stretch from northern Georgia to central Maryland.
Central and eastern Virginia, western North Carolina and southern portions of Maryland and Delaware are most at risk for heavy rain, though these storms will not be as extreme as those on Monday. Storms with the heaviest rain will arrive by Tuesday evening. They will likely move slowly, and rainfall rates of more than two inches per hour could be possible.
Showers will start dissipating on Tuesday night, clearing up in the region by early Wednesday. Weather will remain quiet until showers once again move through the Carolinas and Pennsylvania Wednesday afternoon.
Exactly where and when these storms will develop is still uncertain, but it will not take much rain to cause sudden flooding in places where the ground is already saturated. The highest threat of flash flooding is along and east of the Blue Ridge mountains.
Much of the area impacted by flooding Monday had seen up to 300 percent of their normal rainfall over the past two weeks.
Record-breaking flood events have happened nearly back-to-back in recent weeks, most notably in Texas' Hill Country, where more than 130 people died after
catastrophic flooding on 4 July
. New Mexico, North Carolina and other East Coast states have also seen life-threatening floods and historic rainfall this month.
More than 3000 flash flood warnings have been issued so far this year by National Weather Service offices around the country, with the current count higher than any previous year through 14 July since such records began in 1986.
Overwhelming rainfall is becoming more prevalent in a warming world, as rising global temperatures drive weather toward extremes. Hourly rainfall rates have grown heavier in nearly 90 percent of large US cities since 1970, according to a recent study from the nonprofit research group Climate Central.
Storms thrive on warm, moist air, and with the nation approaching peak summer heat, this month has seen the perfect conditions for flooding rain.

Concern as signs point to more heavy rain for Nelson Tasman region
The Nelson Tasman region is facing months of work to recover from recent bouts of bad weather. Photo: RNZ/Nathan Mckinnon Forecasters say more bad weather is brewing which could bring significant rain to parts of the country, including the top of the South towards the end of this month and into early August. Earth Sciences New Zealand (formerly GNS Science) meteorologist Chris Brandolino said the next seven to 10 days would be dry from tomorrow. It would bring some short-term respite for those involved in the cleanup in the Nelson Tasman region. However, there would be "a pivot point" as the end of the month approached and more heavy rain could be on the horizon. Brandolino said the source centred on the Tropics which has been experiencing a lot of unusually warm water and there was a tilt toward La Niña conditions. When that happened in the north it resulted in more rain and thunderstorms in Australasia. "So when these lows come across from Australia or the Tasman Sea there is this source of moisture pooling and waiting, and if that area is active with rain and thunderstorms, that low pressure over the Tasman Sea when it does form, it can tap into that moisture over the Coral Sea, over Papua New Guinea, over the West Pacific and the Tropics and siphon that down." That is what the top regions of the South Island have been experiencing in the last few weeks, Brandolino said. "It is a river in the sky that's able to leverage that moisture and turn it into rain." It would take a break but in about 10 days the weather would change again. "That's the concern - there could be these areas of heavy rain again ... those are the themes that are emerging for very late this month and as we work into the first week of August." An example of some of the widespread damage to roads and infrastructure in the Nelson Tasman areas. Photo: Supplied/ Nick Smith An army of volunteers has swung into action in the Nelson Tasman region to help flood-affected farmers and orchardists with the massive cleanup ahead. It comes as the government announces a $600,000 support package for farmers, growers and foresters across the battered district. The chairperson of the Top of the South Rural Support Trust Richard Kempthorne told Morning Report the funding was "great news" and "very helpful". He expected there would be a lot of requests to the Mayoral Relief Fund, which will receive the largest portion, for things that weren't covered by insurance. As a former mayor of Tasman District, he had seen many adverse weather events. "This surpasses all of them by quite a chunk. ... It's just enormous, you cannot plan for it." The cleanup could be "swamping and daunting" and he advised people to try and take it one step at a time to avoid being overwhelmed. Farmers and growers should ask for help if they needed it, Kempthorne said. Silt, stones and debris would need to be removed by heavy machinery while the standing up of fences would also be a priority. There was a lot of thought going into what needed to happen in the river system and stopbanks in the longterm, Kempthorne said.

There is a heavy rain watch in place for Auckland tomorrow. File photo. Photo: 123RF Heavy rain is heading towards Auckland and the east coast of the North Island, but the most sodden parts of the South Island are set for a reprieve from the downpours, says MetService. There is a heavy rain watch in place for Auckland, Great Barrier Island, Coromandel Peninsula and Waikato north of Lake Waikare from 4amThursday through to 2pm, with localised downpours possible. Northland, where a suspected tornado hit Tuesday morning , has also been issues a strong wind watch for Thursday afternoon and evening. The wet weather is then expected to head east, with another heavy rain watch for Gisborne/Tairawhiti and Hawke's Bay north of Napier, starting at midday Thursday and lasting until 6am Friday. MetService has warned that streams and rivers may rise rapidly, with possible surface flooding, slips, and difficult driving conditions. The weather agency has also warned that there may be snow on the highest part of the Desert Road on Thursday afternoon. Further south, areas such as Nelson - which are still cleaning up after multiple deluges in the past few weeks - will get a break from the current bad weather, with relatively clear skies for the next few days. After a wet and wild few weeks for the top of the South Island, drier days are finally in store ️ Follow along in real-time with satellite and rain radar imagery on our website: Sign up for Ngā Pitopito Kōrero , a daily newsletter curated by our editors and delivered straight to your inbox every weekday.

Tasman flooding: Council says most of its annual budget spent in a fortnight
About 40 roads remain closed in the Tasman District following widespread flooding and slips. Photo: Supplied/ Jodie Reed The Tasman District Council says most of its annual budget has been spent in a fortnight after being ravaged by heavy rain and flooding. The clean-up has been continuing in the waterlogged district following a month of historic rainfall, culminating in last week's destructive storm that has caused widespread damage. The costs have already been swelling with up to $500,000 being absorbed daily on fixing the local roading network. The state of emergency is expected to be lifted on Thursday ahead of a one-month recovery transition period. The council's community infrastructure and group recovery manager Richard Kirby told Morning Report the district 's infrastructure was facing a repair bill of "between $20-25 million". He said about 40 roads remain shut. "Up to 200 people, about 15 heavy machines and trucks, all over the district opening roads," he said. "Hopefully we'll have them open in the next couple of weeks." The most arduous obstacle for council contractors was the type of material they had to shift, particularly in the Motueka Valley. "It's just like porridge slipping off the hills. As soon as they push it more comes down," Kirby said. "That's an ongoing challenge. It's all on at the moment." There were further challenges underneath slips where roads had been washed out, and bridge approaches, Kirby said. In Kaiteriteri, a geotechnical assessment was needed to ensure a slip could be stabilised and the damaged road beneath could be reinstated. Kirby said the busier roads presented the biggest challenges, compared to the quieter back-country roads. He later told RNZ that the annual budget would likely be all gone by next month. Earlier on Morning Report, he said the council would be requesting financial assistance from the New Zealand Transport Agency. "We'll be making a bid to NZTA and seeing if we can get some extra subsidy. "Although we're opening roads, we still have to go back and do permanent repairs. That'll probably take 18 months or even two years to complete." The council said the critical stopbank in the Motueka Valley had "held up really" well following government-funded upgrades. Some erosion of stopbanks had occurred in Tapawera area on the Motueka and Motupiko rivers. "The river teams are up there just to see what urgent areas need repaired in the event we have another rainfall," Kirby said. "They're prioritising what work they need to do to get some resilience into those riverbanks." An apple orchard has flooded on SH60 in Motueka. Photo: SAMUEL RILLSTONE / RNZ A fruit and vegetable delivery company is warning of a spike to the cost of vegetables around the country following the destructive weather. Produce prices would sharply increase in the coming months due to the knock on effects of widespread flooding, particularly in the Tasman district last week. Co-founder of fruit and vegetable rescue company Wonky Box Angus Simms told Morning Report the effects would not be felt for another two to three months. After a string of bad weather in recent weeks across the top of the South, growers have reported a delay in planting, he said. "The immediate effects we haven't necessarily seen. Growers have been able to get into fields, they've been able to harvest. They've been able to make that work. "Whereas actual planting delays will be happening here which is going to have an ongoing effect later on down the line." Simms said the shortage would be likely be seen with green vegetables such as cauliflower and broccoli, and less so with root vegetables. Produce had begun to "steady out" at a retail level following Cyclone Gabrielle. "What we're seeing in the green space already is greens are slowing and values are coming back for growers," Simms said. Fruit production is considered a jewel in the Tasman district's local economy and a major export industry. Harvesting of fruit products including apples and pears finished a few months ago, Simms said. "Anything that's already been picked and harvested has been stored," he said. "The products that have been stored tend to be safe." Some fruit growers were facing repairs of their infrastructure ahead of next season, Simms said.
