Hi @idefix37, there are multiple sources we use for buoys and ships, mostly those available at NOAA ftp. Taking a look at your example, one report can be found here https://tgftp.nws.noaa.gov/SL.us008001/DF.an/DC.sfmar/DS.ships/sn.0155.txt where the station is clearly identified as a ship (plus I cannot see id 41040 being reported anywhere else).

Aaccording to manual on codes buoys are identified as ZZYY, ships as BBXX.

Can you please comment on that, is there anything I am missing? or can you provide alternate data source where this buoy is properly identified?
thanks.

We source the alerts from meteoalarm.eu, where these are not provided on district level, so at this moment it is not possible. CAP alerts are still an experimental feature, we are not sure at the moment if future developments will be done in this area. If so, we would consider this improvement for sure.

Thanks for the info, this is obviously a bug. Will be fixed soon.

@weatherfan we are not showing minor severity alerts by default. we had an issue with wrong expiration of US warnings, but that should be fixed now. could you please provide exact example at the time when you see some discrepancy? The layer is experimental, help us to improve it!

@tomber42 these warnings are of minor severity. we are not showing those in Windy. Check https://www.dwd.de/DWD/warnungen/cap-feed/de/2.49.0.1.276.0.DWD.PVW.1545364440000.260d9396-db21-42e4-ad71-44169e7e6e4b.DEU.xml for example

@gkikas-lgpz German was added + some bugs in alert processing and time filtering were fixed. Please note that we are not displaying any warnings with Severity below Moderate.

@sekritfox thanks for the info. US feed processing had some bugs, it should be fixed now. Please note, that we are not displaying any warning below Moderate severity and date filtering is always with respect to the time zone of the Windy user (capAlerts for "today" are those valid between current time & upwoming midning).

@tomber42
German feed had different structure, now it was added too.

@gkikas-lgpz thanks for info. I will have to check it in more detail, just few quick remarks:

• Germany - we know about it, their alert feed doesn't correspond to what is a "standard" for other EU countries. separate parser will be developed for that
• general disrepancies between Windy/meteoalarm - it already happened many times, that meteoalarm shows different alerts from the ones reported in the data feed. we found a cases where alert was not visually shown in the metoalarm map, although it was present in data feed and was valid and active in given time period. Same happened vice versa - alert shown in map was not present in data feed.
• also the understanding of how to treat today/tomorrow differs between Windy and meteoalarm

We plant to fix/change couple of things in CAP alerts layer, once this is done, I will provide more detailed post of how it is implemented and how to treat the data provided by that layer.

In the meantime, if you really want to compare Windy against the source, you have to check the data source itself, not the resulting map at meteoalarm (example for Sweden can be found at http://meteoalarm.eu/ATOM/SE.xml). If you find a discrepancy there, please let us know

@idefix37 Nope, Switzerland data are shown. Take a look, there are some active warnings now ...
