Portsmouth weather: Hour by hour forecast as yellow weather warning issued for the South East

The warning for rain will be in affect for all of Sunday, January 5 and last until 9am on Monday, January 6. Heavy rain is set to impact much of the region including Portsmouth although the biggest impact will be felt in the South West.

A Met Office spokesperson said: “Further spells of rain, heavy at times, through the course of Sunday and overnight into Monday morning, will bring the potential for some difficult travelling conditions and perhaps some localised surface water flooding.

“Through this period, a further 15-20 mm of rain could fall quite widely, with perhaps 30 mm in a few locations, this most likely in southwest England. Parts of southeast England are less likely to see heavy rain after early afternoon on Sunday. Rain, perhaps with a little wet snow on its back edge, will clear to the east through Monday morning.”
