Possible Tidal Surge 21st Dec

[Tobster]

Just for info, On the Gov.UK there is a medium warning of a tidal surge from tomorrow am across the broads network.

[Bluebell]

Yep, had an email the the EA warning the barrier is to likely to be raised at Herbert Woods today until Sunday when they will review…😎

 

[marshman]

Wind again I expect!

[JanetAnne]

It's here!

[Hylander]

Think you would have to limbo under Wroxham at the moment.

 

    

[Hylander]

I see Herby Woods is again under deep water, it has only just dried out.

theres problems  at Hemsby  already. Some idiot took down a barrier to take a photo  last night. Didn't  put it back.The barrier  was to stop people  falling in the water.Some people  I just understand.

Very tactfully put Ian, I'm sure you thought something else at the time....

The tide at Lowestoft was 1.5m above predicted level but thankfully, after not going out very far at all on the following low tide, it now seems to be returning to more predictable levels.

I suspect other places other than the Broads were affected up and down the East Coast too

At 8.50 am this morning, Friday, 22nd December, the River Thurne above Potter Heigham bridge had reached record levels. The river was overtopping the flood defences at locations it has never before overtopped.

At Haddiscoe where trains were suspended just in case a particularly low "low tide" preceded a pair of locked high tides. https://check-for-flooding.service.gov.uk/station/6209

This is now the highest tide we’ve seen here at Thorpe St Andrew in 19 years of being on the island. Chickens have been rescued and furniture raised up in the bungalow. Last time it was like this Roger’s two girls actually canoed through the bungalow. 

The quay heading our end is a lot higher. The bungalow and workshops and associated boardwalks are all underwater.

Merry Christmas everyone.

Lots of dead & dying fish also reported at Upton dyke. 😥

[JanetAnne]

Oulton broad road bridge 4.00 this morning

[Bytheriver]

There are huge amounts of silt on the quay at Reedham and Riverside where the tide came up the street gullies this morning

[OldBerkshireBoy]

Very high (record high?) at Brundall overnight. Has dropped by around 9" now. (13.00)

I know Brundall Gardens has had some flooding to the yard, the slipway is under water and the holiday cottages car park is flooded.

Fortunately the marina staff have been around checking boats and ropes.

Odd you should say that. I cast an eye over Romney Marsh this morning and, apart from the odd puddle here and there,  It showed no evidence of flooding. But then again, the Broads Authority's writ doesn't apply here and the drains are kept well-dredged by the farmers. 

[marshman]

To be fair Steve, the situation is not really comparable at all.

Any surge coming down the North Sea is effectively "stopped" to some extent by the Dover Straits which acts like a neck of a bottle and in relative terms the Romney Marsh is quite a small area - neither does it have any major rivers draining through it. Someone somewhere may know the actual figure, but the catchment area of the 3 main rivers draining out through GY is enormous - I doubt its much less than 1500 sq miles! (Thats a total guess off the top of my head!)

If the BA were responsible for drainage of fields and marshes, then your tolls may be even higher - thats down to the IDB's who generally cope quite well but like many places they can only cope with a certain amount that falls out of the sky!! What occurred last night was just not a very high tide, aided and abetted by a NW breeze, but a classic example of a (blocking) tide where the tide didn't just go out very much if at all -see here

I agree but all the same this is not a spring tide. We are on neap tides at the moment.

I am sure that on top of all the recent flooding certain questions are surely bound to be asked whether the flood alleviation program is working?
