Possibly Silly Yorkshire Weather question

Is it silly to assume that the weather up in the Ingleborough area has been sunny recently?

I've a permit to go down Juniper Gulf this weekend but am thinking that it's a bit rainy.  :cry:

Has anyone been up there recently?

You might already be aware of the CDG's Vis-Bot but if not:

It has been very very wet in the Dales over the last few days - however we went down Juniper when it was almost in flood and could easily do everything except the last pitch. - On every other pitch you can traverse and stay above the water.

If it stops raining for a day or two then go for it as i've done Juniper on a previous occasion when it was also wet and that time we did get down the big pitch.

Went down Notts 2 on New Year's Eve, and the amount of water didn't seem anything other than normal. Not been in there before so can't compare it, but the streamway wasn't backed up and it was no problem to walk upstream.

Juniper is fine in the wet. Loud - but fine.

I did it in near speight conditions, we used the 'wet weather' entrance pitches. but you can stay out of the water most of the way.

The final pitch is pretty intimidating, deafening with little chance of comunication - so make sure all your party are fully competant on the SRT as you dont want to be faffing about. It may also be worth sending a couple at a time down and up. You really wouldn't want to be waiting around whilst people ascend. We stopped about 1 minute at the bottom of the pitch and felt like we'd been lashed by a hurricaine.

There was no way we could have gone any further i.e. down to the sump. Not without a large inflatable raft.

Take care on the scambly bit between the penutimate and last pitch. I nearly came a cropper de-rigging due to the amount of spray making climbing a bit difficult.

I did it once when the penultimate pitch was impassable.

This makes me want to ask, what is the amount of rainfall in millimeters that corresponds to a heavy days rain which makes it difficult to go caving on the Allotment?

On average its about 8mm a day since Christmas.

Yep last pitch would have been impassable when we went on Saturday - 21mm.

Couldn't actually get to last pitch as where you have to climb up over a boulder just prior to the pitch a massive waterfall was coming down!!

Also what are speight conditions - something to do with Alan Speight? Perhaps spate conditions.  ;)

I was with Sam in October 2005. Trip report here has info about the amount of rain we had:

http://ukcaving.com/board/index.php/topic,1510.0.html

The usual disclaimers apply. You can buy me a drink if we ever meet as thanks! If you get stuck in there don't worry about it  ;)

Does writing in green cause problems for people who are colour blind?

So after a week or so of no rain on the day of 21mm it was too wet for the last pitch.


I don't know what spate means either way it is spelt.

How long is a piece of string?

Apologies if I'm teaching you to suck eggs here but ... the amount of rain the day before is only part of the answer. What is also very relevant is the saturation levels of the ground. At the moment the ground is probably pretty much saturated in The Dales with the result that any rain that falls will run immediately into caves flooding everything. In this situation a small amount of rain can make a big difference. In Summer, you also need to be careful of very dry conditions prior to rain, as the ground is so dry the rain also runs straight over it giving massive run off.

To further complicate things, in my experience a few weeks of 8mm of rain will make for quite wet conditions during Winter but this will be lees marked in Summer. I assume this is due to the lack of surface evaporation in Winter.

Exactly why I'm asking, the ground is saturated up there so like you say rain goes straight into the caves, so what is a heavy days rain? I'm having difficulty transfering a millimeter of rain into what the water will be like in the cave.

Im intriged by the above comments.

IIRC - the penultimate pitch was a 30 m ish Bell shaped pitch - with a constricted take off. No problems in flood there - well away from the water.

Bit of a boulder hop on ledges above the stream to arrive atop big spray lashed boulder, where the rest of the last rope can be rigged down a 10foot climb down at the far side - You are then very near the top of the massive final pitch which again is well away from the main waterfalls (there were two when we where there) The normal one on the left (looking out) and a smaller one raining from the inky blackness above - but luckily - its against the back wall.

Very spray lashed though.

I cant imagine them being 'impassible'. Its hard to imagine any more water than we had. Not saying there isnt though.

The full force of the water hit the rope near the bottom. I was with Mike Wooding at the time.
