A wall of stormy weather is set to bring a high winds of up to 100kmph sweeping across the nation in a matter of hours as the Met Office issues more weather warnings.

The national weather agency has put yellow alerts in place for the east of England, northern England, the east Midlands, Wales, Yorkshire & Humber, Devon and Cornwall and almost the entire south coast from Penzance to Hastings.

A warning for strong winds is in force today from 9am until midnight, along with another warning for rain in force from 4pm today until 9am tomorrow.

For the north west around Liverpool, a rain warning is in force from midnight tonight until 8pm tomorrow, with an alert for wet weather also affecting Yorkshire and the east Midlands from 8am tomorrow until 3am on Tuesday.

With yellow warnings for wind, it’s advised coastal routes and sea fronts could become hazardous because of large waves and spray, and public transport, including buses, ferry services and rail, could be disrupted.

On the roads high-sided vehicles may run into trouble, leading to delays for motorists on some routes.

New maps from the forecaster WXCharts show the high winds and intense rainfall hitting large parts of the country today and tomorrow.

According to the Environment Agency flooding is still a problem for many, with 36 flood warnings, where flooding is expected, and 68 flood alerts, where it is possible, in force across England.

Netweather.tv forecaster Ian Simpson said a “month’s worth of rain” could be on the way on Monday and Tuesday following a cold weekend for many this weekend.

He said: “This weekend has got off to a cold and sunny start for most of us, and for much of the UK it will stay dry and sunny during the rest of today.

“However, cloud will increase from the south-west on Sunday, ahead of another southerly tracking low pressure system that is forecast to bring rain into the south-west of England and south Wales late in Sunday, and then to a large area of Britain during Monday and Tuesday.

“There is some disagreement between the forecast models regarding where the heaviest and most persistent rain will end up, which will be a critical detail for the areas that have already been affected by flooding.

“For example, the UKV model (the UK Met Office high resolution model) run this Saturday morning has the rain mostly concentrated near the English Channel, whereas the GFS (Global Forecast System) model has the largest rainfall totals affecting the south of Ireland, north Wales and an area of northern England and the north Midlands. The GFS model is forecasting 30 to 50mm of rain in two days across a large area.”

“Thus, it will be one of those events where we probably won’t be able to be sure of where the most heavily affected area will be until close to the time.

“While none of the forecast models are suggesting anything as extreme as what some regions saw last Sunday and Monday, there is still potential for some areas to see up to a month’s worth of rain in just 36 to 48 hours, which would be enough to exacerbate flooding in areas that are already affected by flooding, plus areas where water levels are currently running high.”
