Heavy rain and strong winds have continued in eastern Scotland, where there is a Met Office amber warning in force for Grampian, Angus, and Perth and Kinross until 18:00 GMT.
Rainfall accumulations of 60-80mm are likely, with as much as 100-120mm over high ground.
Totals since Wednesday evening may exceed 150 mm in a few places. This is expected to lead to some surface water and river flooding across the area.
There is also a wider yellow warning across the rest of eastern Scotland where rainfall accumulations of 30-60mm will be seen widely.
The Met Office warns that with the ground already saturated from recent rain and and snow thaw, this may lead to some flooding in places.
A strong south-easterly wind in north-east Scotland will also make it feel particularly unpleasant.
Additional yellow warnings are in force on Thursday across south-east Wales, Somerset and Devon from 08:00 to 16:00 and Northern Ireland from 10:00 to 23:59.
Persistent and heavy rain in these areas through the day falling on saturated ground could lead to some flooding and transport disruption.
On Thursday morning there were nearly 160 flood warnings in force across England, Scotland and Wales.
Elsewhere, the weather remains generally cloudy and breezy, with rain and drizzle.
On Friday, the UK will be impacted by Storm Ingrid, which was named by the Portuguese weather service due to the impacts expected there from strong winds and heavy rain.
The centre of Ingrid will move close to the south-west of England and north-west France.
Winds in the UK will strengthen on Friday, with gusts up to 65mph expected.
While not as powerful or dangerous as the near 100mph winds experienced in south-west England during Storm Goretti, there could still be some impacts.
It will likely stay windy through Saturday as the centre of Ingrid stalls to the south-west.
The rest of the UK will avoid any impacts associated with Storm Ingrid, but the rain in eastern Scotland will continue, with some snow over higher ground.
