Understanding the difference between National Weather Service watches and warnings is critical to being prepared for any dangerous weather hazard, including hurricanes.
A watch lets you know that weather conditions are favorable for a hazard to occur. It literally means "be on guard!" During a weather watch, gather awareness of the specific threat and prepare for action – monitor the weather to find out if severe weather conditions have deteriorated and discuss your protective action plans with your family.
A warning requires immediate action. This means a weather hazard is imminent – it is either occurring (a tornado has been spotted, for example) – or it is about to occur at any moment. During a weather warning, it is important to take action: grab the emergency kit you have prepared in advance and head to safety immediately. Both watches and warnings are important, but warnings are more urgent.
- Hurricane / Tropical Storm Alerts
- Tropical Storm Watch: An announcement that tropical-storm conditions are possible within the specified area.
- Hurricane Watch: An announcement that hurricane conditions are possible within the specified area.
- Because outside preparedness activities become difficult once winds reach tropical storm force, watches are issued 48 hours in advance of the anticipated onset of tropical-storm-force winds.
- Action: During a watch, prepare your home and review your plan for evacuation in case a Hurricane or Tropical Storm Warning is issued. Listen closely to instructions from local officials.
- Tropical Storm Warning: An announcement that tropical-storm conditions are expected within the specified area.
- Hurricane Warning: An announcement that hurricane conditions are expected within the specified area.
- Because outside preparedness activities become difficult once winds reach tropical storm force, warnings are issued 36 hours in advance of the anticipated onset of tropical-storm-force winds.
- Action: During a warning, complete storm preparations and immediately leave the threatened area if directed by local officials.
- Extreme Wind Warning – Extreme sustained winds of a major hurricane (115 mph or greater), usually associated with the eyewall, are expected to begin within an hour.
- Action: Take immediate shelter in the interior portion of a well-built structure.
Additional Watches and Warnings may be issued to provide detailed information on specific threats such as floods and tornadoes. Local National Weather Service offices issue Flash Flood/Flood Watches and Warnings as well as Tornado Warnings.

How to Stay Informed
Use all of the above information to make an informed decision on your risk and what actions to take. Listen to recommendations of local officials on TV, radio and other media and to NOAA Weather Radio All Hazards for the latest tropical cyclone information.
The National Weather Service (NWS) continuously broadcasts warning, watches, forecasts and non-weather related hazard information on NOAA Weather Radio All Hazards (NWR). The average range of the 1000+ NWR transmitters is 40 miles, depending on topography. For the best performing NWR receivers, NWS suggests you look at devices certified to Public AlertTM standards.
These radios meet specific technical standards and come with many features such as Specific Area Message Encoding (SAME), a battery backup, both audio and visual alarms, selective programming for the types of hazards you want to be warned for, and the ability to activate external alarm devices for people with disabilities. Similar to a smoke detector, an NWR can wake you up in the middle of the night to alert you of a dangerous situation.
