[non-METNO] Portugal terminates alphanumeric TEMP/SHIP/SYNOP on 22 April

There is information from several sources that Portugal is going to
terminate alphanumeric TEMP/SHIP/SYNOP on Wednesday 22 April 2015.
Unfortunately the news was not brought to me via official channels of
WMO, but certain reliable people are involved in the situation.

We are interested in the updates. Mainland Portugal is not a big
country, but they operate stations in Atlantic islands where station
observation is really rare.

So far GISC/RTH/RSMC Tokyo is not receiving BUFR versions of the
reports. I found IU[KS]A0[12] LPMG at GISC Melbourne, but the content
is reformatted BUFR in separated parts A and B as far as I checked on
Wednesday and Thursday. Code experts say the BUFR will be B/C
compliant, so what we see now cannot be used as sample for
preparation.

It is really important that NWP centers have real example in advance.
Every NWP centers in my knowledge filter incoming reports by GTS
heading and/or staion identifiers. The common practice is that the
data is removed from the blacklist (or added to whitelist) only after
confirmation of the quality of data for certain period of time.
Abrupt changes without advance notice will cause interruption of data,
which has negative impact on the quality of forecasts. The impact
might be small this particular time, but in general we cannot welcome
sudden change of operation.
