In the list of notable rainfall events is Fleet (Hampshire) 26/09/33. Was
there once an official weather station in Fleet? If so do you know where
it was and what happened to it?

I've got MSN Explorer working on it now. It's like waiting for Godot
to wade through sludge.

Bloody hell it actually opened that javascript link:

A historical study of extreme rainfall events in the 20th Century
Will H. Hand

Extreme rainfall events by their very nature are rare but common
enough to require consideration of the possibility and associated
serious flood risk by DEFRA. It is therefore vital that signals of the
possibility of such events occurring in any given region be recognised
as early as possible, preferably 24 hours or more in advance.

The primary aim of this study was to examine events in the 20th
century in order to ascertain any common hydrological and
meteorological features that could be used operationally to provide
early recognition of the possibility of an extreme rainfall event that
could lead to serious flooding.

***
Perhaps the MetO should convert to international standards so that in
emergencies all computers can retrieve their data.

It's not as if open source is going to ruin the drive to make the MetO
pay for itself is it? Or is there an intention to put DRM in the mix?

Thanks for that link, Michael. Will's link just stalled on me - after I'd
pasted it together - although it's now working. Presumably it couldn't cope
with the sudden heavy demand from uk.sci.weather readers yesterday.

In 1933 there were three official raingauges in Fleet. One, Fleet
(Home Wood), recorded 131.1 mm, almost all of which fell in about 4
hours, in a very localised thundery downpour (at South Farnborough,
just 8 km away, only 7 mm fell). Other totals from the area on this
date:

Fleet (Crookham) 107.9 mm
Fleet (Winchfield) 102.1 mm
Hook (Nateley Hatch) 62.5 mm
Greywell 62.2 mm
Odiham S Wks 61.5 mm
Upton Grey 51.1 mm
South Warnborough 52.8 mm
Rotherwick (Tylney Hall) 71.4 mm
Hartley Wintney Council Offices 99.1 mm
Bramley (Street Farm House) 68.6 mm
Stratfield Turgis 62.5 mm
Heckfield 38.9 mm

All but the last are from British Rainfall 1933, and daily records for
all of these sites will be available in the Met Office archive in
Exeter. There's also a map of this famously localised intense storm in
BR 1933 (p 69).

I suspect the density of raingauges for analysing the July 2007 events
will be nothing like as good as the network in 1933, more's the
pity ...

-- Rainfall of 20 July 2007

Total Location Total Total
to 09Z after 09Z
69.0 Reading University 26.5 42.5
98.6 Maidenhead 70.2 28.4
63.7 Wokingham 24.5 39.2
63.6 Henley-o-T (St Marks Rd)
81.1 Stratfield Mortimer 25.8 55.3
50.5 Middle Assendon 23.1 27.4
79.5 Sindlesham
78.3 Bagshot
59 Henley-on-Thames
64.1 Shiplake (32.1) (32.0)

Between 0730BST and 0833BST 51mm of rain fell
in Maidenhead, probably the largest hourly total
in the town since 92mm fell in 60 minutes at
a raingauge at Maidenhead-Lowood on 12 July 1901

The latter fall is still the UK record for a 60-minute fall!!

On 12 July 1901 a total of 107.7mm fell at The Firs,
Maidenhead - the wettest rainfall day on record in Maidenhead.

Schools used to have weather stations but no longer, due to vandalism.
What government agency has taken on such a mantle of irresponsibility?
