Yea, this new page having the issues it does, and the old page finally shutting down, started a big hate thread towards WU. They have claimed that more decimal places will be added, and to their credit, some more decimal places have shown up in the last week.
With rain rate, they seem to use a floor function instead of rounding, so 0.99" per hour shows as 0" per hour.
Fingers crossed they get their stuff together and manage to bring WU back to its former glory.
