More than 300 properties were flooded Tuesday, many close to England's northeast coast, as some areas received more than a month's average rainfall in 24 hours and the historic market town of Morpeth in Northumberland was swamped.

More than 80 flood warnings were in place across the country, mostly in the northeast, plus 139 less serious flood alerts.

Water levels were set to continue rising along the Severn river and Ouse river in Yorkshire, according to the Environment Agency.

Flooding caused severe disruption to roads and railway lines across the north of England and Wales on Tuesday, including the East Coast Mainline which links London with Leeds, York and Newcastle.

"An unusually deep area of low pressure for this time of year will continue to bring heavy rain and strong winds to parts of the UK for the next day or so," Martin Young, chief forecaster at national body the Met Office, said Tuesday.

"The rain will gradually ease away from Scotland, but further heavy rain is expected across parts of Wales and southern England where up to 40 millimetres (1.6 inches) of rain may fall locally in places over the next 24 hours."

More than 100 vehicles were trapped for several hours on the A1 road in northern England because of flooding, with parts of the road -- which runs from London to Edinburgh -- remaining closed, the BBC reported.

The weather was set to return to "fairly standard autumn weather" on Thursday, the Met Office said, warning the public to remain alert in the meantime and avoid floodwaters.

"Eighteen of 27 districts of Assam have been hit by floods with 1.4 million displaced and 11 people drowned in separated incidents in the past week," the Disaster Management agency said in a statement.

The floods, caused by relentless rains, marked the second round of massive flooding in two months to hit India's impoverished northeast and come towards the end of India's June-to-September monsoon season.

Nearly 130 people died and six million were displaced by floods in Assam state in July.

Rescue officials said in the latest floods, at least 2,200 villages had been swamped by overflowing waters from the rain-swollen Brahmaputra River.

Himanta Biswa Sarmah, the health minister of Assam state, told AFP that a "maximum health alert" to avert outbreaks of diarrhea or diseases such as typhoid had been declared in the devastated zone.

The annual monsoon provides vital irrigation for India's farmers but also claims many casualties from flooding and landslides.

Officials said flooding victims had been evacuated to temporary shelters on higher ground.

"We've dispatched doctors and paramedics to ensure there is no outbreak of disease," Sarmah said in Guwahati, Assam's largest city.

Victims and an opposition party staged protests in flood-hit areas against what they said were shortages of emergency supplies in the Congress-ruled state.

"The government has failed to provide adequate relief supplies including food and medicines," said Sarbananda Sonowal, a local leader of India's main opposition Bharatiya Janata Party. "In many parts of the state people are even living without food," he added.

Rehab India Foundation, a voluntary group said heavy rains disrupted its plans to supply food and other essential items to flood-hit people.

Almost the entire 420 square kilometres (162 square miles) of Kaziranga National Park was also flooded, the Press Trust of India reported.

The wildlife park is home to the world's single largest population of one-horned rhinos. A 2012 census in Kaziranga counted 2,290 of the rhinos, out of a global population of 3,300.

The species declined to near extinction in the early 1990s and is listed as "vulnerable" by the International Union for Conservation of Nature.

Kaziranga has fought a sustained battle against rhino poachers, who kill the animals for their horns that fetch huge prices in some Asian countries where they are deemed to be an aphrodisiac.
