The red flood warnings for Shrewsbury were issued at around 7.15pm on Tuesday and warn people that flooding is "expected" and to act now.
The red alerts remained in place on Wednesday morning after other warnings for the River Vyrnwy at Maesbrook and Melverley were removed. Meanwhile, flood alerts remain in place for the River Dee catchment from Whitchurch to Chester, the rest of the River Severn in Shropshire, the Severn Vyrnwy confluence and the Tern and Perry catchments.
The Shrewsbury update from the Environment Agency says the River Severn is expected to peak at the Welsh Bridge on Wednesday morning.
It comes after heavy rainfall and large amounts of melting snow on the Welsh hills.
The warning says flooding is expected at the West Mid Showground and The Quarry, as well as at Sydney Avenue, Frankwell and St Julian Friars car parks.
The warning states: "River levels have risen at the Welsh Bridge river gauge as a result of heavy rainfall. Consequently, flooding of property, roads and farmland is expected to continue."
It says the 'predicted peak at Welshbridge' is 3.4 to 3.6m this morning.
It adds: "Further rainfall is forecast over the next week. We expect river levels to remain high for the next few days. We are closely monitoring the situation.
"Please avoid using low-lying footpaths near local watercourses and plan driving routes to avoid low lying roads near rivers, which may be flooded."
