A developing area of low pressure is expected to track north across the UK through the weekend. The heaviest rainfall is currently expected to develop on the western flank of the low, with the western, less populated areas of the Tyne Tees region most at risk from potentially 20 to 40 mm of rain, and locally perhaps 50 mm in 12 hours.
The rain will more likely be showery for central and eastern areas at times with persistent and sometimes heavy rain more likely across The Pennines and Northumberland.
Strong winds will present an additional hazard later in the day, becoming particularly gusty over hills in the west.
Rain will continue for a time into Sunday and strong winds will affect hills for a time with gusts to 45mph.
Conditions should improve for us during the second half of the weekend with a mixture of sunshine and showers developing behind the main rainband.
Further scattered but heavy and thundery downpours may occur where sunny spells develop.
