Storm Aurora was named by Météo-France because a depression is expected to bring strong winds to northern France on Wednesday and early Thursday, with coastal areas expected to be the most affected.
The storm was named by Météo-France because greater impacts are expected. The French Meteorological Service is part of a different storm naming group than the Met Office, which means that the next storm named by Met Eireann, KNMI or the Met Office will always be Storm Arwen, and will be named when impacts more important ones are expected. in one of these countries.
The northern part of the frontal system wrapped around Storm Aurora looks out over southern England as the system moves east. Associated heavy rains have prompted the Met Office to issue a yellow warning for rain covering southern England, from 4 p.m. Wednesday to 3 a.m. Thursday morning. However, the most powerful and widespread impacts associated with Aurora will be in its southern flank, which lies in the north of France.
Heavy rains in England could see between 15mm and 25mm falling in the warning zone, with up to 50mm possible in some places. This will be associated with a few coastal gales, with winds up to 45 mph in some exposed locations, and largely windy elsewhere.
“The worst weather conditions associated with Aurora will be on its southern flank, over northern France. Aurora’s northern limit will catch the south of England, giving us a peek, ”said Met Office chief operational meteorologist Dan Suri.
“What this means for us is heavy rain tonight and tonight. The Channel Islands, however, being closer to France, will be more directly in the line of sight and will experience high winds tonight and tonight. Of course, strong winds will affect the English Channel as well, so maritime interests are encouraged to keep abreast of shipping forecasts. ”
The unstable theme is expected to continue across much of the UK through the weekend, with sporadic downpours expected, along with a shift to cooler conditions and a lingering possibility of overnight frosts, particularly in areas North.
Thursday will see the continued influence of some snow showers on the heights in Scotland, this risk also extending to the heights of Northumberland Fells and the Pennines.
Friday is expected to be drier for many, but rain showers are still expected in the west of Scotland and parts of central and northern England and Wales and persistent windy conditions.
The weekend is expected to see more persistent rains, with a band of rain affecting the far north-west early on Saturday and spreading across the UK throughout the weekend, with the heaviest rains expected in the west of Scotland, where 40 to 60 mm of rain could fall. 24 hours. Northern Ireland, northern England and Wales could see up to 20mm of rain fall in 6 hours. This band of rain weakens as it moves towards the southeast, but the southern and central areas will still see areas of thicker cloud and light rain moving slowly.
Met Office operational meteorologist Adam Thornhill said: “It looks like an unstable weekend will be the main theme for most as an area of persistent rain and strong winds arrives in the far northwest on Saturday. morning. This will gradually slide south-easterly throughout the weekend and the far south-easterly will see the best of the weather set before the rain arrives late on Sunday.
“The unstable theme will coincide with the drop in temperatures from the unusual heat wave we have seen in recent days, as they approach fall averages with generally highs of 14 ° C, although Sunday will see again. milder temperatures. ”
