An autumnal start to the new week but with warm tropical air and strong winds

After last week's autumnal feel with chilly starts, this week holds on to the autumnal mood with some wet and windy weather for the country but with a twist.

As we move into autumn and the jet stream starts to re-orientate itself, strengthening out of the US and Canada towards Europe. Then we start to see the traditional areas of low-pressure which have spun up in the Atlantic bringing us wet and windier weather.

Often during these wet and windy interludes, we get the remnants of ex-hurricanes or former tropical systems which hurtle towards us.

Last year, you may remember Ex-Ophelia, which brought strong and damaging winds of 71 mph to the west of the UK and Ireland. But it also lifted temperatures back into the twenties with an iconic red sun for much of the day as it pulled dust from the Sahara and smoke from wildfires in Spain and Portugal.

How is Helene going to impact the UK?

As we move into the beginning of this week, the remnants of ex-Hurricane Helene will spin into the UK, bringing some wet and windy weather for northern and western parts. Meanwhile, temperatures are set to rise across the board as warm and moist tropical air moves northwards.

Two words that don't often go together in forecasts, "warm and windy" but it's quite right for the start of this week!

As a result of Ex-Helene moving in across the UK, the Met Office have issued a weather warning in association with the winds.

Although they won't be exceptionally strong, with many trees still in full leaf it's likely to bring some minor impacts, through Monday night and into Tuesday.

Why was it not called Storm Ali?

Last week the Met Office revealed the storm names for the 2018-2019 season, but why wasn't this deep area of low pressure referred to as Storm Ali - the first named storm of the season?

When a weather system (hurricane, tropical storm, sub-tropical storm) that has developed in the Atlantic has been named by the National Hurricane Center in Miami, the name is not changed and is referred to as ‘ex-Tropical Storm Helene’, for example.

So there you have it, a Storm with a tropical kick, keeping temperatures above average for the next 24 hours, plus some windy and wet weather for the north and west.
