Copied from the day - will update once data recvd next month

Perhaps some high rainfall totals today - these are my calculations adding totals on the shoothill floodsite

So far if I am reading it correctly 0900-0900hrs

Honister - 129.8mm
Seathwaite 98.4mm
Mickeldon - 77.4mm
Ennerdale 46.8mm
Isel Valley 43.2mm
Brathay Hall - 37.6mm
Shap - 31.6mm
Ulpha 28mm
Drumburgh - 13.4mm
Brampton 11.8mm
Carlisle 10.6mm

Between 5am and 9am this morning Honister has had 82mm rainfall - thats just about my Octobers average, what a thoroughly wet place, the rain must come down like stairs rods all night long.

Updated figures 2100hrs

Honister - 0900-0900hrs 137.6mm
Honister - 0900-2100hrs 213.2mm

EA Figures are now out

9th - 31.8mm
10th - 153.6mm
11th - 59.4mm
12th - 63.8mm
13th - 32.6mm

5 day total 341.2mm
Month Total 712mm

YES it was wet but no where near any record . It still holds the record 24hr rainfall total of 341.1mm (5/12/2015) so this 5 day total of 341.2mm is miles away

712mm for the month equates to 170.5%

The Met'O chart for October suggests a fairly average month - but why it doesn't show the large anomalies within the Lake District I do not know.

I did contact the Met'O and point out the apparent discrepancy and the following is their response (Paul, look away now)

Further to your enquiry for the NCIC the NCIC have provided the following response:

"The correspondent is correct in pointing out that most of the Lake District did, according to our monthly rainfall map, have near-average rainfall totals in October 2017. I note that there are just a few pixels on the map in that region that appear light blue, i.e. had between 125% and 150% of the long-term average for the month.

The discrepancy is down to the fact that none of the three stations specifically mentioned in the correspondent’s email were actually included in our provisional run of the statistics. The calculations we do on the 1st day of the month are always, of necessity, based on only those observations already available to us by that point in time; most of these are Met Office automated weather stations. Usually around 6 months in arrears we do a “final” run of the stats, which include all available stations (including those manually read by volunteer observers, and gauges maintained by other authorities), and the level of regional detail is sometimes then enhanced – we might expect, then, to see larger percentages-of-average appearing on the map in the Lake District in this instance.

Stations in and around the Lakes that were included in our October provisional summary and map are Carlisle, Drumburgh, Newton Rigg, Blencathra, Shap, Bridgefoot, St Bees Head, and Levens Hall."
