: Maintenance
- Tipping bucket rain gauge was obstructed and was
unplugged around 8:30am by Dwayne Frens of the
Michigan Celery Cooperative.
- The five-minute precipitation total recorded at
08:35 and the hourly total reported at 09:00 are
therefore likely to be inflated.

Michigan Celery Cooperative measured 2.78 inches
(storm total).

: Daylight Savings Time Adjustment.
- Daylight Savings Time Ended on Day=301, Time=200.
- Time of Obs were modified by one hour (subtracted)
from Day=301, Time=200 through Day=301, Time=610.
: Phone Line Activated and Data Collection Started
Phone Number: (see setup notes)
