Among the 21 alerts are along the River Thames in the Oxford area and Abingdon and the River Ray in Islip.
Property flooding is not expected in these areas and river levels are falling on the lower sections of the River Ray and River Thames.
During the height of the flooding, Abingdon Road was closed for several days as fire crews worked round the clock to pump water out of the submerged road.
The recent River Thames alert reads: “River levels are expected to continue slowly falling.
“We are monitoring the situation. Avoid using low-lying footpaths near local watercourses and be aware of floodwater remaining on the flood plain as river levels recede.”
While the River Ray alert says levels are “falling” the area is “sensitive to further rainfall”.
It adds that “no further flooding of low-lying land and roads is expected.”
The flooding in Islip since the turn of the year has been described as being the worst since 2019 by homeowners.
Villagers in Islip were previously told to move possessions and valuables to safety and to use flood protection such as sandbags flood barriers.
Paul James, 70, who has lived on Lower Street for five years said it is “becoming more frequent” each year.
The flood warning comes in place as the temperature is set to drop to below zero in Oxfordshire this week as cold as Arctic air is set to hit the country.
Other parts of the UK could be hit worse as the Met Office is warning of snow and ice that could cause disruptive conditions.
The warning for snow and ice is in place from 3am on Monday, January 15 until 11am the same day across parts of north east Wales and north west England from Liverpool to the West Midlands.
Scotland also faces a similar warning that is in place until midnight on Monday as the Met Office placed a warning across the whole of Scotland.
An Oxfordshire Fire and Rescue spokesperson said: “Winter roads can be dangerous when there’s snow, ice or sleet. Our top tip is to slow down.
“If you’re driving up a hill, leave plenty of room between other cars or wait until it’s clear so you don’t have to stop part way up.
“Keep a constant speed and try to avoid having to change gear on the hill.
“When driving downhill, slow down before the hill, use a low gear and try to avoid braking. Leave as much room as you can between you and the car in front.”
