You're too kind.  I think I'll go for an ark instead.  Can you help me with that?

Not if you are referring to the angel in the Yorkshire carol "Ark the erald angel sing"

No it bloody isn't right - doesn't anybody read my posts? 

1000 litres is one cubic metre. So 1000 litres of water on one square metre would have a height of 1 metre = 1000 mm.

So 1 litre of water equates to 1 mm height of water over 1 square metre. Not one ml which I said.

So when they talk of 191 ml this has to mean a height of 191 millimetres, and is an ignorant error. If they give the volume in litres, not ml, then that would be per square metre and equivalent to the same height in mm.

You are quite correct.  The measurement should be in mm.

Standard rain gauge

The standard NWS rain gauge, developed at the start of the 20th century, consists of a funnel emptying into a graduated cylinder, 2 cm in diameter, which fits inside a larger container which is 20 cm in diameter and 50 cm tall. If the rainwater overflows the graduated inner cylinder, the larger outer container will catch it. When measurements are taken, the height of the water in the small graduated cylinder is measured, and the excess overflow in the large container is carefully poured into another graduated cylinder and measured to give the total rainfall.

In locations using the metric system, the cylinder is usually marked in mm and will measure up to 250 millimetres (9.8 in) of rainfall. Each horizontal line on the cylinder is 0.5 millimetres (0.02 in). In areas using Imperial units each horizontal line represents 0.01 inch.

Fascinating, thanks. What amuses me is they bother to give all these measurements and omit the obviously critical one, the surface area of the top of the funnel. I suppose you are left to work it out.

The cable car might itself be on a somewhat restricted timetable due to the weather, but access from the top of the Teleférico to Teide's peak is now confirmed as closed to the public for security reasons until, at present, Monday 9 December. The announcement comes as the Canarian Government issues a pre-alert for continued rains over the weekend, and Aemet's yellow alert starts for rains in the western islands. JA

OMG OMG OMG
Now they are issuing WHAT?    . . . . . . pre-alerts 

So is a pre-alert an alert that there might be an alert. . . . . (In this particular case for a weekend when not much at all is going to happen.)

I despair . . . these guys can't even get the alerts right . . . how can they possibly get the alert that there might be an alert right.

I would like to preempt the pre- alert for the alert next Tuesday. Bloody windy alert. There you are  . . . a pre-pre-alert

Here you go ...

Just a little tiny bit over the top.

I will have to get my lawyer to check that out, but I think it is pretty clear that they have the wrong day.

Why don't you two get a room?

(And duke it out!)

You seem to think I'm criticising Janet?

But she is merely reporting the bureaucratic excesses of the public administration.

And it shouldn't bother me that they are producing official documents announcing alerts that there may be an alert for what is going to be a fairly mild weekend with a few scattered downpours. They have to be seen doing something to justify their thieving.
And it shouldn't bother me that the newspapers then put it all over the front page and everybody gets all hypochondriacal about it and nobody really notices that it isn't quite as bad as they were making out. It shouldn't bother me that it has become part of the information background noise of modern times . . . how long before pre-alerts come in colours too? That shouldn't bother me either, keeps them busy.

It bothers me a bit that they just can't get it right.

But it's really going to piss me off on Wednesday when they realise that screaming "wolf" from the rooftops isn't enough and they close my children's school for two days . . . . . . . because it's raining a lot.
This coming Wednesday will probably warrant an alert - yes - but they will have to think of something else because we get an alert every two or three weeks - and so they will set up a pseudo-martial law and start closng services. 

It all starts with unnecessay pre-alerts on sunny days.

I mean they have actually started to issue PRE - ALERTS to warn of coming alerts when the alert itself only means something might happen and often doesn't.

It might be handy if you are planning a barbecue or other event next week.  We get used to planning events for dry sunny days 2 weeks ahead here!
