Two severe flood warnings, meaning an imminent danger to life, have been issued for communities on the Somerset Levels.
The highest level of alert was issued by the Environment Agency for the A361, between East Lyng and Burrowbridge and the second for Saltmoor and North Moor.
Residents of Fordgate, North Moor and Moorland are being advised to leave their homes as the River Tone spilled into Currymoor reservoir.
The council said up to 150 properties could be affected.

Earlier nine of the highest warnings were in place with klaxons sounding in many communities across the south coast.
There has been widespread disruption across Devon and Cornwall from flooding, scores of felled trees and damage to numerous seafront structures.
A major incident has been declared in Dawlish by police and homes had to be evacuated when part of the sea wall and railway line was washed away and a section of the road collapsed.
Exmouth, Sidmouth and Seaton seafronts have been closed, and the high tides have also flooded properties in Exmouth, Lympstone, Starcross and Topsham.

Coastguard and fire and rescue crews are in attendance in these areas.
There are also reports of further damage in Penzance, with teams currently inspecting the damage to South Quay.
There are also issues reported with the pier at St Mawes. The road has been closed by the police while the situation is being assessed and members of the public are being asked to avoid the area.
Four schools are closed, Leedstown, St Hilary, Ludvan, all near Penzance, as well as St Mawes School on the Roseland.
The Environment Agency was predicting waves of between 8-10 metres likely to affect the south coast of Cornwall.
Earlier today the organisation raised the number of severe flood warnings, meaning potential danger to life, to six.
This now covers more or less the entire south Cornwall, Devon and Dorset coastline.
In the South Hams, four homes were evacuated on the seafront at Torcross this morning as the high tides smashed the fronts of properties.
Teams from South Hams District Council’s works department are currently surveying the damage.
A spokesman for South Hams District Council said: “Our teams have been down there since early this morning trying to make sure people are safe as possible in the circumstances.
“The properties were evacuated because there was danger from broken glass and further damage caused by the breaking rollers.
“We also have unconfirmed reports that there may be a breach in the sea defences and that the rebuilt road in front of Slapton Ley is threatened. We are awaiting reports back from our engineer at the scene.”
Major disruption is still ongoing at Kingsand and Cawsand, South Cornwall, where last night emergency crews had to use chainsaws to access the villages.

Cabinet member for communities, Geoff Brown, told the Western Morning News this morning that the damage had been widespread.
He said that travel was fraught this morning and urged people not to drive unless their journey was vital.
"It has been a hard night for the county," he said.
"There have been problems everywhere.
"In Newlyn, the sea wall has been breached again and in Penzance firefighters were called out to seafront properties.
"It was not the case that they had to deal with flooding, but that windows in some hotels had been broken by boulders thrown up by the sea."
He confirmed 100 trees were down in the county.
An estimated 7,500 homes, mainly in Bodmin and Redruth, remain without power this morning with services expected to be reconnected by midday.
He said that emergency services "had to cut their way into Kingsand using chainsaws" last night such was the level of damage to roads in the area.

With repair and clean up work barely under way in many of the region’s seafront towns and villages, the south coast could be hit by another storm surge this morning as strong winds whip up already heaving seas.
Surf forecasters Magicseaweed, meanwhile, have predicted waves could peak at 33ft (10 metres) today on some beaches and at up to 43ft (13 metres) on Saturday.
Chris Tubbs, Met Office deputy chief meteorologist, said: “We have more Atlantic depressions heading our way during the rest of the week and over the weekend. Heavy rain and gales sweeping in from the west for Wednesday brings the risk of further flooding in some areas and possible travel disruption.
“There is now increased confidence that much of the southern half of Britain will see further heavy rain on Thursday evening and night, and that will be quickly followed by another storm early Saturday.”
The embattled Environment Agency has issued flood warnings for most of the south coast with high tide at about 10am today. In all, 12 flood warnings are in place, along with 35, lesser, flood alerts.
John Curtin, head of incident management at the agency, said: “Following the wettest January on record in some places we are now set to experience successive bands of heavy rain heavy rain fall lasting into the weekend.
“With further river and coastal flooding expected this week we have teams working around the clock to protect homes and communities, and over 117,000 homes have been protected over the past three days.
“Strong winds and waves could be dangerous, and we would urge people to stay away from coastal paths and promenades, and not to drive through flood water.
“In the face of this severe weather we would also remind people that they can sign up to receive free flood warnings, check their flood risk and keep up to date with the latest situation on the Environment Agency website and on social media using #floodaware.”
In December and January, the Exeter-based Met Office issued 101 weather warnings for rain and 58 for strong winds across the country.
Severe gales, up to 80mph, are forecast on some exposed coasts at lunchtime today with inland gusts of up to 60mph expected to bring down trees.
“A gradual change to more showery conditions is expected today but still with some longer spells of rain, which could bring a further 20-30mm (0.8-1.2ins) over the hills in Wales but with 10-15mm (0.4-0.6ins) being a more general figure,” the Met office said.
“The public should be aware of the risk of disruption from either the wind or rain elements in this warning.”
Yet another warning is in place from 5pm on Thursday into Friday morning with heavy and persistent rain likely to affect much of southern England. Severe gale force winds are expected to return in the early hours of Saturday.
“Computer models have moved into much better agreement now for this weather system but unfortunately the most likely outcome is not good news,” the Met Office said.
“This means that there is now increased confidence in a period of persistent rain, which may bring a fairly widespread 15-25mm (0.6-1ins) to the areas covered by the warning, possibly around 30mm (1.2ins) in some southern counties.
“This rain, falling so soon after the previous batch seems likely to exacerbate problems with flooding, especially as further heavy rain seems very likely early on Saturday.”
Cornwall Council estimates the weather has already caused £4 million worth of damage across the county while in Devon it stands at about £2 million.
Both councils said they had emergency teams on standby to react to incidents while others were actively monitoring the most vulnerable areas.
“We know that many areas of Cornwall are still clearing up after the severe weather we have experienced over the past few days but we need to ensure that local residents are getting ready for this next period of bad weather “ said Geoff Brown, the council’s cabinet member for homes and communities.
“We are asking people to follow the advice on dealing with the potential severe weather, and would remind motorists not to drive through flood water.”
At the weekend, the main road in Bude had to be closed with waves overtopping defences causing flooding.
A video uploaded to YouTube is said to show the moment waves breached sea defences in the coastal town of Bude, while surfers and kayakers were reported to have ridden the tidal surge as it pushed through the town at the weekend.
Another YouTube posting shows powerful waves breaching the sea walls at St Ives in Cornwall.
