Timely and accurate weather observations are basic to the development of meteorological and oceanographic forecasts in support of fleet operations. Since the U.S. Navy may be committed to operations anywhere in the world, total global observations of meteorological and oceanographic conditions are required. Ships in port are required to make regular weather observations and to report by electronic means unless there is a nearby U.S.-manned weather- reporting activity. In-port weather observations and reports of guard ship arrangements may be used for groups of ships at the discretion of the senior officer present. In such instances, the weather logs of exempted ships should bear a notation of the guard ship(s) and effective dates and times. Table 8-1 provides the minimum requirements for reporting weather observations by Navy ships. Not all Navy ships make weather observations. Ships in port usually receive local weather messages that are sent out at various times to all commands. Weather messages usually contain the latest information compiled using U.S. weather satellites. They can show the approach of storms long before they reach your area. As a POOW you may not have to make weather readings or log weather information; but, at the approach of a storm, you may have to go to the bridge and record weather information for the OOD. If you ever have any questions about weather reporting, you should always consult the duty Quartermaster, as that knowledge is a part of the Quartermaster rating. 8-18 SMALL CRAFT GALE STORM HURRICANE DAYTIME SIGNALS NIGHT LIGHT SIGNALS WIND SPEED (KNOTS) UP TO 33 34 - 47 48 - 63 64 - UP Figure 8-6.
