THE Met Office has upgraded its weather warning for later this week, predicting that an incoming storm could bring deep flood water.

Storm Callum has been upgraded from a yellow to an amber weather warning, which covers a large part of Pembrokeshire on Friday, October 12 and Saturday, October 13.

The storm is expected to bring heavy rain between 6am on Friday and 6pm on Saturday, particularly over south-facing hills.

The Met Office has warned that homes and offices are likely to be flooded, and fast flowing or deep floodwater could cause a danger to life.

Areas in the south and south west could see between 50 and 100mm of rain by the end of Friday, with as much as 120 to 160mm likely over high, south-facing ground.

On Saturday, areas over high ground could see a further 50 to 80mm of rain.

Natural Resources Wales’ (NRW) have said they are sending out their emergency response teams to prepare for the storm, checking that flood defences are in good working order, clearing gulleys and ditches, and installing temporary defences.

NRW will issue flood alerts and warnings if rivers reach trigger levels, with teams monitoring river levels 24 hours a day.

Gary White, NRW’s Duty Tactical Manager, said: “The current forecasted rain could cause flooding this week, especially in south and west Wales, and we are urging people to prepare themselves.

“Our teams are doing all they can to reduce the risk for communities, but if there is flooding we want to make sure people are doing all they can to keep themselves safe.”

NRW has also advised people to take extra care will driving, to avoid walking or driving through any flood water, and to avoid fast flowing rivers and streams.

Winds of up to 60 mph are also expected to hit Pembrokeshire, which combined with high tides could lead to some coastal impact due to large waves.

While heavy rain is expected to continue into the Saturday, the wind is currently believed to ease off by Friday evening.

If flooding does occur there is a chance that trains or bus services could be cancelled.
