Weather warning as heavy rain to bring flooding and travel disruption

A weather warning has been issued as heavy rain is to bring flooding and travel disruption across Scotland.

The Met Office yellow alert warned of a risk of fast flowing or deep floodwater causing danger to life.

STV meteorologist Sean Batty has said Scotland should brace for a month’s worth of rain within 24 hours.

“What can’t be ignored though is that some of our computer models have been indicating totals as high as 150mm – which can be taken as a worst case scenario,” he said.

Scotland to see month’s worth of rain with risk of flooding

Sean Batty

“With average rainfall totals for May around 50-70mm for the east of Scotland it’s very likely that many will see a month’s worth of rain, and in some spots possibly a lot more than that in 24 hours.”

The yellow weather warning comes into force at 12pm on Wednesday and remains in place until 6pm.

ScotRail said it plans to introduce speed limits for safety reasons which will extend journey times.

The Met Office warned of a chance of power cuts and loss of other services to some homes and businesses.

There is a small chance that homes and businesses could be flooded, causing damage to some buildings, and where flooding occurs, there is a chance of delays or cancellations to train and bus services.

Spray and flooding could also lead to difficult driving conditions and some road closures with the risk that some communities will become cut off by flooded routes.

After a fairly prolonged settled period for much of the country things are about to change in the next 24 hours with a low pressure system rolling out of Germany and moving into Scotland on Wednesday afternoon.

Windier conditions will develop during Wednesday with the strongest winds along the north and east coast and gales over the hills.

The main issue will be heavy thundery rain which will move west throughout Wednesday and into Thursday with significant totals and flooding possible.

The east of the country will see the highest totals with 30-40mm falling quite widely and up to 80mm in some spots. What can’t be ignored though is that some of our computer models have been indicating totals as high as 150mm – which can be taken as a worst case scenario.

With average rainfall totals for May around 50-70mm for the east of Scotland it’s very likely that many will see a month’s worth of rain, and in some spots possibly a lot more than that in 24 hours.

This is likely to lead to some flooding issues on Wednesday night and into Thursday, especially after the recent drier conditions which will have hardened the ground a little in some areas, which leads to increased run-off.

For those thinking ahead to the holiday weekend, it does look like it should settle back down with a lot of dry weather on Saturday, although some showers will return on Sunday and Monday.
