Strong winds are expected on Tuesday leading to disruption to transport, damaged or fallen trees, damage to buildings and power outages.
· Yellow WIND Warning (Low Likelihood of Medium impacts) valid 0900 on Tuesday 25th August to 0900 on Wednesday 26th August 2020.
Next 12 hours:
Today will see a mix of sunshine and showers. The showers could potentially be heavy in places with isolated surface water possible but, as with any showery situation, many places will remain dry. Showers will gradually die out during the evening.
Tonight / Tomorrow:
An area of low pressure, now named as Storm Francis, will develop to the west of the UK tonight, move across Ireland tomorrow morning and then east across northern England and into the North Sea by tomorrow night. This will bring heavy rain and unseasonably strong winds across much of the UK.
Areas of rain, locally heavy, are expected to move northeast across southeast England tonight, gradually clearing to the east tomorrow morning. Showers, isolated heavy, are expected to follow from the west during the day before dying out during the evening.
More significantly, the southerly wind will increase tonight before turning south-westerly and increasing further tomorrow morning. We expect to see gusts of 50-60 mph in places and as much as 70 mph on exposed coasts and over hills. This is enough to damage or bring down trees (especially as they are still in full leaf), lead to disruption to transport, isolated damage to buildings and power outages. Additional impacts are possible due to the fact that we are still in school holidays and many people are camping or participating in outdoor activities. There are also more outside seating areas than normal, with parasols, due to Covid-19 social distancing plans.
The Met Office have issued a Yellow WIND warning (Low Likelihood of Medium Impacts) to cover the potential impacts from the strong winds which look at their strongest for SE England during the afternoon and evening. Details of the warnings can be found on the Met Office website, Hazard Manager or on the Met Office App.
The wind will turn west to north-westerly and gradually ease during Wednesday morning. There will be sunny spells at times, with a few showers but it should become mainly dry later in the afternoon.
It will remain rather unsettled during the rest of the week with further heavy rain or showers at times, especially during Thursday and Friday, possibly accompanied by strong winds at times. Conditions look like gradually improving during the weekend as high pressure briefly builds from the west.
