Does anyone know a link/page that provides the timing for release of the fax
charts ? Whilst chart changes for a specific date/time ares interesting to
see if the forecast is changing, its often confusing to see (say) 60h, 72h &
84h for the same date/time, IYSWIM. I'm normally most interested in the new
132h chart but have never worked out quite when its released or the timing
of individual chart updates.

e.g. UKMO fax charts here : http://www.meteonet.nl/aktueel/brackall.htm

Many thanks

A rough guide is appended to each chart here

Also, David Haggas asked a similar question earlier in the month, here's a
copy of my reply :-

"Generally speaking all charts valid up to T+72 will be available by 1930Z,
often much earlier, with the T+24 usually issued between 1600-1630Z.

T+84, 108 and 132 are only produced in the morning, normally based on 00Z
data. T+96 and T+120 are only produced in the evening, generally based on
12Z data and usually both available by 2300Z.

The precise issue times and hence availability will vary for a variety of
reasons, not least the weather situation itself. Plus it's somewhat
dependant on how quickly they're handled by the various web servers that
provide them."

HTH.
