11/10/06

Well the storms last night in Devon gave me a daily 1800-1800 total of 56.4 mm.
This is the highest 24 hour total I have ever recorded since moving here. Last
highest was 51.7 mm on 23/10/04. A very large fall but not exceptional for this
area.

There were 4 separate storm cells. The biggest was around 2340 local which had a
rainfall rate of 128.3 mm/h and a 20 minute total of 8.1 mm. Bar fell by 0.5 mp
in 10 minutes 2340-2350 (wake low of storm). Lots of lightning but thunder was
intermittent. Rainfall, however, was torrential but also came in short bursts.
No problems up here whatsoever (we never do with rain). Now like it has never
happened. Flash flooding elsewhere in Devon though.

Now, the manual total was 56.4 mm but my AWS VP2 read just 42.7 mm, why the big
discrepancy? All I can think of is that the rates were so large that the tipping
mechanism could not cope. A sobering thought for users of AWS I think. Comments
appreciated on this?

I'm chuffed. (a) we had a storm, (b) I got a pretty big rainfall total.

Will.
