Storm Doris

Update 23rd February

Storm Doris continues to bring the winter’s strongest winds across the East of England.

Impacts from the damaging winds will continue to be realised over the coming hours, adding to the widespread disruption already experienced.

An updated Met Office Amber Warning for Wind covers all of the East of England – remains valid until 2000 today, with that Medium Likelihood of Medium Impacts. This means we could see further damaging gusts of 60 to 70mph – and perhaps exceed 70mph for a while. Indeed, today’s highest gust so far has been recorded at Weybourne on the Norfolk coast with 81mph

Winds will finally ease down from the west later today – and especially during this evening and overnight in all areas. So Bedfordshire, Cambridgeshire and Hertfordshire will be the first to see winds decrease. Essex – and in particular, Suffolk and Norfolk as winds become north westerly – will finally see winds slowly ease down through this evening and overnight.

 

Update 22nd February

We are now entering a spell of very unsettled weather – with winds over the coming days expecting to peak in strength on Thursday in association with ‘Storm Doris’.

A deep area of low pressure remains on course to track across central parts of the UK during Thursday, with high winds that could cause widespread disruption.

However, a subtly more southerly position for the storm as it enters the North Sea – has implications for our region regarding the Wind Warnings for tomorrow. This is because the associated swathe of severe gales are now expected to extend further south – with many places now at risk of seeing some damaging gusts of wind.

As a result, the Met Office has now updated an Amber Warning for Wind on Thursday that now covers all counties here in the East of England. The Warning is valid from 0600 until 2000 tomorrow and brings a Medium Likelihood of Medium Impacts.

In the Amber Warning area, the very strongest winds could be short-lived – but we could experience damaging gusts of 70 to 80mph for a while, with gusts of 60 to 70mph perhaps occurring over a longer period of time.

Once again to reiterate, medium impacts from the strong winds include:

  • Injuries and danger to life from flying debris
  • Some structural damage, such as slates dislodged from roofs
  • Transport routes and travel services affected, with longer journey times expected and disruption to road, rail, air and ferry transport.
  • Interruptions to power and/or other utilities and services

 

Storm Doris will also bring some heavy rain for a time, with around 10mm falling in many places during the day – this adding some surface water to what could be challenging travelling conditions during Thursday.

In addition to the Amber Warning, the Met Office has also updated the Yellow Warning of Wind for all of the region and includes those areas just south of the Amber Warning area, so the southern halves of both Hertfordshire and Essex. This Warning is valid from 0500 to 2000 on Thursday and brings a Medium Likelihood of Low Impacts, where gusts of 50 to 60mph are possible widely.

Uncertainty remains regarding the precise timings of the very strongest gusts – however, with the low pressure sweeping in from the west, it is from the west where will see the risk of severe gales transfer across our region – before heading out into the North Sea.

Based on the latest indications and as a general guide for us in the East of England, some damaging gusts could well occur: from late morning for Cambridgeshire and Bedfordshire, during the afternoon for all of us – and until early evening in Suffolk, Norfolk and Essex.

Winds are expected to gradually ease during Thursday evening and night – leaving Friday a much quieter day with a fresh breeze. Further rain and strong winds are possible on Saturday, when gusts of 40 to 50mph could occur for a time.
