Well spotted Keith !

No the 18.7 is from the manual raingauge. At the time my Davis VP was
under-reading at 18.0 mm. It is now 1935 local and is actually reading 19.3 mm
(which is an odd number). It measures rain in 0.01 inch tips (0.254mm tips). So
to read 19.3 mm it must have done 76 tips.
So it is possible to get odd numbers as it measures in inches and then converts.

This is one problem I have with AWS recording. With my manual gauge I can record
to 0.1 mm resolution. But the AWS is only capable of 0.254mm resolution. Or so I
believe ?

Be a little while yet before live data appears. But I *will* get the weatherlink
software as it will make instrument comparison much easier.
Thanks for the interest (in future I'll make it clear which instrument I'm
referring to) !

Will.

I'm curious WIll, is the 18.7mm value obtained from your new Davis VP?
The reason I ask, is I thought the metric settings accumulated
rainfall in 0.2mm increments, so I would have expected 18.6 or 18.8mm.

Looking forward to seeing some of your data "live", well evenings and
weekends :-)

Rainfall now stands at 18.7 mm for this event, so nothing severe (or even
heavy)
yet.
Still continuous moderate, occasionally heavy rain, however.

Wind still light to moderate with max gust of just 22 knots.
Took a wet walk up to 450m this afternoon and wind only force 4-5 occasionally
6
up there.

Long way to go yet though.

Will.
