... As of 0900GMT this morning (17th January, 2014), since this wet spell began on 13th December (35 days/7 weeks), we've had 337 mm (out of annual average 1981-2010 of 847 mm) representing 40%/two-fifths of our 'normal' rainfall. The last 24 hours brought 21 mm after a steady procession of heavy rain showers yesterday & overnight - a couple with small hail yesterday late morning. Nearby Hurn, for comparison, has had 332 mm over the same 35 days.

... As at 29/0900GMT Jan 2014 ... for West Moors:

January rainfall = 226.0 mm & since December 13th, total = 413 mm, within a whisker (49%) of half-an-'average' year's PPN total in just under 7 weeks.

As regards Hurn (based on 06-06 rainfall readings):

January rainfall = 223 mm / 257% of the 1981-2010 LTA and is comprehensively the wettest January in the published dataset (MO web site 1957+)

Total now threatening the likes of the second-wettest /any-month/ which is November 2002 (235 mm), but the wettest calendar month is probably safe at 259 mm in October 1960.

For December 2013/January 2014 composite total = 415 mm, which smashed the previous highest of 339 mm in the wet winter of 2000/01.

But it's not over yet!

A little birdie tells me that the MO are going to issue an update at 1100 tomorrow (Thursday) regarding winter rainfall in context ... they will say that the SE & CS England has had its wettest January in their truncated 1910+ dataset.

The rain continues.
60 successive days from 13 Dec to 10 Feb.
Total 432.8 mm.

That is a lot for what is equivalent to a two month period.

Ended up with 65 successive days of measurable rainfall, 13 Dec to 15 Feb, here in Wembury
before being broken by a dry day (measurements to 1800z) yesterday.

Have had rain since of course, in fact at 1945z yesterday!

The winter total to 1800z yesterday now stands at 505 mm.

Copley stats to 19th February:-

Winter to date 301.1mm (129% of normal 233.0mm)
Year to date 210.8mm (146%)
February to date 96.4mm (138%)

Wettest winter since 2006-2007 so I can't really join in.
Back to enjoying the rain-shadow!

... still quietly winding up the rainfall hereabouts - despite all the siren voices telling us that we can relax! Admittedly not the intense rainfall of recent weeks.

As of 1800GMT this evening (19th February), here in West Moors we're up to 566 mm for the winter (DJF) so far.

At nearby Hurn, (provisional/using SYNOP-based data), they're up to 558 mm, about 67% of the all-year (1981-2010) average, and 224% of the winter-time average.

With the rain falling across the EWP domain currently, I suspect we will finally exceed the wettest winter in that series set in 1914/15. We're already 'clear' of the highest value in the regional SWEP series.

Following a fall of 11.1mm in the 24hrs to 9am this morning, the total rainfall for the winter period at Dorchester now stands at 607.2mm - 196% of the average and a full 100mm above the previous record for the town set in 1989/90. The 1981-2010 February average here is 309.5mm.

The total for February to date is 141.5mm (the wettest since 2007 at 150.2mm) compared to the average of 82.4mm.
The February record here is 197.9mm (1923) - probably beyond reach!!!
