UK weather: La Nina alert as ex-hurricanes from US set to smash Britain this autumnThe UK could be facing the calm before the storm with the next hot spell as there is a very different outlook for the end of September and October when ex-hurricanes could hit

26 Aug 2021


Brits could be blasted from strong storms that were once hurricanes from late September and a colder autumn is predicted with the arrival of La Nina, it is reported.

Sun seekers are finally basking in warmer weather that is expected to run into the first few weeks of September - but after that the outlook is more stormy.

The ex-hurricanes are expected to hit the UK shores having moved their way across the Atlantic towards the end of September.

Forecaster Brian Gaze, of The Weather Outlook said that low pressure will arrive due to what is remaining from hurricanes.

He told the Express : ”At the moment the computer model data which I’m looking at, which goes out about a month ahead, is suggesting this transition into more unsettled weather during the second half of next month.

“What looks like happening at the moment, perhaps by the end of first week of September, it may well be turning more unsettled in the north west of the UK and then that more unsettled weather with rain will probably spread south-eastwards through the second week of September.”

A forecaster is also predicting for October that the UK could be hit by La Nina like last year. This weather pattern in autumn sees a high pressure in the mid-Atlantic which stops weather systems bringing mild air to the UK and so the country could be hit by a cold, icy blast.

Tyler Roys, Senior Meteorologist and a lead European forecaster at AccuWeather said that La Nina could come later than last year.

Mr Roys said: “There are going to be some similar atmospheric factors at play this Autumn when compared to last Autumn.

“These factors are not 100% the same as last year.

“The biggest factor that will be similar will be La Nina. Our thinking is that by October we will likely be in a La Nina, with the transition to La Nina happening this September.”

The meteorologist added: “This transition occurred in August of last year.

“Last year between late September and early October, there was only one such storm and it impacted much of western Europe, not just the UK."

La Nina can also bring an ex-tropical depression - stormy weather that brings heavy rain, said Mr Roys.

“In the end compared to normal for late September to early October, there is a chance we see the remains of a tropical feature impact the UK, while below normal chance for non-tropical storms that bring torrential rains and damaging winds to impact the UK," he said.

“You can get a few inches of rain in a short duration, along with that of course the stormy wind and storms.

“How deep they go and what impact they have will depend on what’s contained within them and by that I mean particularly the rain side of things if it drags in some tropical air.

“All of this begs a question if we will see something more tropical.”

In the worst case scenario there could be severe storms but Mr Roys said that we should have advanced warning before they hit.

He continued: "It’s calm before the storm. It’s that scenario, the silence before the storm and that could well materialise.

“I’m not saying it will. But we should have good notice before them arriving and we should have a good warning before the storms come.

“So we should be able to warn people before anything that could have severe or catastrophic impacts arrives in the UK. But that’s the way it looks.“
