A watch means hurricane conditions are possible. A warning means they are expected. Both call for action before tropical-storm-force winds arrive.
Hurricane watch
NHC generally issues a hurricane watch about 48 hours before the expected onset of tropical-storm-force winds in the area. That lead time helps people prepare while outdoor work is still possible.
Hurricane warning
NHC generally issues a hurricane warning about 36 hours before expected tropical-storm-force winds. Complete protective actions and follow instructions from local authorities.
Check the location and time
A watch or warning applies to a specified area and may change with each advisory. Read the current NHC bulletin and your local weather service; do not infer your status from a track line alone.
Frequently asked questions
Can a watch become a warning?
Yes. NHC updates coastal watch and warning areas as forecasts change. Check each new advisory rather than relying on an earlier map.
Why count from tropical-storm-force winds?
Outdoor preparation can become dangerous before hurricane-force winds arrive, so the lead time is measured from the earlier tropical-storm-force wind onset.
Where can I check my exact area?
Open the current NHC public advisory and your local National Weather Service or national weather authority bulletin.
