If there are no warnings in the designated areas, the broadcasts will
so indicate.
The ocean areas involved are those for which the U.S. has warning
responsibility under international agreement.
The storm warnings are originated by the National Weather Service
(NWS) at 0500, 1100, 1700 and 2300 UTC for WWV and 0000,
0600, 1200 and 1800 for WWVH. These broadcasts are updated
effective with the next scheduled announcement following the time of
issue.
Pilots may find these storm warnings useful even though they are
prepared primarily for mariners. An example follows:
North Atlantic weather west of 35 West at 1700 UTC: Hurricane
Donna intensifying, 24 North, 60 West, moving northwest, 20 knots,
winds 75 knots; storm, 65 North, 35 West, moving east, 10 knots,
winds 50 knots, seas 15 feet.
Information regarding these announcements may be obtained from
the Director, National Weather Service, Silver Spring, Maryland
