In remarks, time entries will use "hours and minutes" if the time reported occurs:

In weather observation reports, specific conventions are established for time entries in the "remarks" section to ensure clarity and uniformity. When reporting a time that occurs during an hour that is different from the hour in which the observation was made, it is essential to include both hours and minutes. This approach avoids confusion by clearly indicating the exact time the event or condition was recorded, which is crucial for accurate interpretation and analysis of weather data.

By using hours and minutes for events that fall outside the observation hour, it provides more detailed timing information than simply stating the hour. This is beneficial for those relying on this data for forecasting or historical reference, as weather phenomena can change significantly within short periods.

For times occurring during the same observation hour, it is acceptable to simply state the hour, as it is generally understood that the entry relates to that current time frame. However, for events that lie outside of that hour, specifying hours and minutes becomes necessary to maintain the precision required in meteorological reporting. Thus, the choice regarding time entries in remarks aligns with the principles of clarity and accuracy in weather observation practices.
