A WEATHER warning for the country has been upgraded to amber, as Storm Callum prepares to hit the region.

The warning is in place for Friday and Saturday, with heavy rain and strong winds expected.

The Met Office report said: "As Storm Callum passes to the northwest of the UK, a period of heavy rain will affect South Wales during Friday, with further spells of persistent and heavy rain at times during Saturday.

"Rainfall totals will reach 40-80 mm widely with 120-160 mm likely over the high ground exposed to the south and south west.

"The rain is expected to be accompanied by strong winds, which when combined with high tides may lead to some coastal impacts due to large waves. In addition, leaves and twigs, brought down by the wind, could block drains and culverts, increasing the likelihood of flooding."

And chief meteorologist Frank Saunders said: “Strong winds at this time of year can increase the rate of leaf fall which can potentially block drains or culverts and, with the heavy rainfall expected over Friday and Saturday, could well heighten the potential for flooding.

"There is also a risk that the high winds associated with Storm Callum, combined with high tides, may lead to some coastal impacts due to large waves.”

Gary WHite, of National Resources Wales, said: "“The current forecasted rain could cause flooding this week, especially in south and west Wales, and we are urging people to prepare themselves.
