If instructions are inappropriate because they are incomplete or do not cover the situation observed, follow the instructions given as closely as possible but exercise your judgment as to what should be reported. WSOH #7 and #8 give minimum requirements. 4. Daily at part-time stations, or once every shift at full-time stations or if there is an aircraft mishap. 5. 90 days is the minimum. SAWRS, however, are encouraged to keep them until visited by an NWS representative. If these forms are available, the NWS representative will be better able to help you improve your observation program. 6. The lower of the two reportable values. This is done in the interest of safety. 7. a. UTC 8. Only if a METAR or SPECI observation was taken between the occurrences of the aircraft mishap and the time you were notified. If this should happen, it would be to your advantage to enter the time of notification, in column 65 (e.g., Notified of ACFT MSHP at 1703). 9. d. drawing a line through the erroneous entry and entering the correct data in black. 10. 24-hour 11. a.
