Description:
Beginning around 1415 UTC on 08/30, the RH readings for
this instrument were frequently around 0 (sometimes
there are erratic spikes upward from 0 for periods of
time). Rainfall appears to have been the cause of the
erroneous readings, as the instrument appeared to fail
in and around the time of heavy rains.

A maintenance visit occurred on 09/04, afterwards data
returned to normal values.
