How people are warned about hurricanes?
Warnings are disseminated through outdoor warning sirens, local television and radio stations, cable television systems, cell phone apps, and NOAA weather radio.
What exactly is a hurricane warning?
A hurricane warning is issued when hurricane-force winds are expected within 24 hours. A hurricane warning can remain in effect when dangerously high water or a combination of dangerously high water and exceptionally high waves continue, even though winds may be less than hurricane force.
How are people warned about typhoons?
Watches are issued 36 hours prior to a tropical cyclone making landfall. Warnings are issued 24 hours prior to the tropical cyclone making landfall. If sustained winds 70 km/h and/or gusts 90 km/h or stronger are predicted, a conventional wind warning will be issued along with the tropical cyclone watches and warnings.
