If you go to:
http://suiattle.net/CapeSmallHarborWeather/mbridge/check-fetch-times.php?show=wx
you can see directly what is in the MBtags.php file that is uploaded from the Meteobridge. It shows:
rain0total-daysum|0.01|// rain total today:|:
rain0total-monthsum|4.09|// rain total this month:|:
rain0total-yearsum|4.09|// rain total this year:|:
rain0total-ydaysum|1.55|// rain total yesterday:|:
If you log into the Meteobridge, you can take a look at the Live Data tab and see if it reports the same thing.
The Almanac page works off data previously reported to WU, so it isn't affected.
