Hurricane Watch vs. Hurricane Warning: Knowing the Difference Could Save Your Life
The difference between a hurricane watch and a hurricane warning is crucial for effective hurricane preparedness. A hurricane watch means hurricane conditions are possible in the specified area, usually within 48 hours, while a hurricane warning means hurricane conditions are expected in the specified area, usually within 36 hours. This difference in time frames dictates the urgency and type of action required.
Understanding Hurricane Alerts: What You Need to Know
Knowing how to interpret hurricane watches and warnings is essential for protecting yourself, your loved ones, and your property. These alerts are issued by the National Hurricane Center (NHC) and disseminated through various channels, including weather forecasts, news outlets, and emergency management agencies. Heeding these alerts and taking appropriate action can significantly reduce the impact of a hurricane.
Hurricane Watch: Prepare and Monitor
A hurricane watch is a heads-up. It signals that hurricane-force winds (74 mph or higher) are possible within the specified area within the next 48 hours. This doesn’t mean a hurricane will hit, but it means the possibility is real enough to warrant preparation.
During a hurricane watch, you should:
- Monitor weather forecasts regularly for updates from the NHC and local news sources.
- Review your hurricane preparedness plan. Ensure you have adequate supplies, including food, water, medications, and a first-aid kit.
- Secure loose outdoor objects that could become projectiles in high winds, such as patio furniture, trash cans, and decorations.
- Consider your evacuation options. Identify potential evacuation routes and shelters, especially if you live in a coastal area or a mobile home.
- Fuel your vehicles and ensure they are in good working order.
Hurricane Warning: Take Action Now
A hurricane warning is a call to action. It means hurricane-force winds are expected within the specified area within the next 36 hours. This is a serious situation that requires immediate action to protect life and property.
During a hurricane warning, you should:
- Follow evacuation orders from local authorities immediately. Do not delay.
- Complete any remaining preparations. Secure your home by boarding up windows and reinforcing doors.
- Gather your emergency supplies and essential documents.
- Move to a safe location whether it’s a designated shelter, a sturdy building away from the coast, or the home of friends or family located inland.
- Stay informed but limit unnecessary travel.
Frequently Asked Questions (FAQs)
Here are some frequently asked questions about hurricane watches and warnings to further clarify the differences and provide practical guidance:
FAQ 1: What does “hurricane conditions” actually mean?
“Hurricane conditions” refer to sustained winds of 74 mph (119 km/h) or higher, and/or dangerously high water and rough seas. These conditions can cause significant damage to property and pose a serious threat to life. The effects are not just wind; rain and rising water can be just as dangerous.
FAQ 2: What is the difference between a hurricane and a tropical storm?
A tropical storm is a weather system with sustained winds between 39-73 mph (63-117 km/h). Once winds reach 74 mph (119 km/h), the storm is classified as a hurricane. While tropical storms are less intense than hurricanes, they can still cause significant damage.
FAQ 3: How far inland do hurricane watches and warnings extend?
Hurricane watches and warnings are typically issued for coastal areas but can extend inland depending on the projected path and intensity of the storm. The NHC and local authorities will assess the risk to inland areas and issue appropriate alerts. Decay of a hurricane as it moves inland does not mean there is no danger. Heavy rain and flooding can extend hundreds of miles inland.
FAQ 4: What factors determine when a hurricane watch or warning is issued?
The NHC considers several factors, including the storm’s intensity, speed, direction, and projected path. They also take into account the potential for storm surge, heavy rainfall, and other hazards. Advanced computer models run several different scenarios to make these important decisions.
FAQ 5: What is storm surge, and why is it so dangerous?
Storm surge is an abnormal rise in sea level during a hurricane, primarily caused by the storm’s winds pushing water towards the shore. It is often the greatest threat to life during a hurricane and can inundate coastal areas with several feet of water, causing widespread flooding and damage.
FAQ 6: Should I evacuate if a hurricane watch is issued?
Evacuation during a hurricane watch is generally not required, but it is a good time to start planning your evacuation route and making arrangements for where you will go if a hurricane warning is issued. If you live in a low-lying area prone to flooding, or in a mobile home, you should be particularly prepared to evacuate.
FAQ 7: What if I live in an apartment building? Should I evacuate during a hurricane warning?
Whether or not you need to evacuate an apartment building during a hurricane warning depends on several factors, including the building’s construction, its location, and local evacuation orders. Consult with your building management and local authorities for guidance. High-rise buildings can have unique wind dangers with upper floor windows at risk.
FAQ 8: How can I stay informed during a hurricane?
Stay informed by monitoring the NHC website (nhc.noaa.gov), local news outlets, and emergency management agencies. Wireless Emergency Alerts (WEA) on your cell phone can also provide critical updates. A NOAA Weather Radio is also a reliable source of information that can continue to operate during power outages.
FAQ 9: What should I do if I am unable to evacuate during a hurricane warning?
If you are unable to evacuate, seek shelter in the safest part of your home, such as an interior room on the lowest floor away from windows and doors. Stay away from exterior walls and hallways. Listen for official instructions from authorities.
FAQ 10: How do I prepare my home for a hurricane?
Prepare your home by securing loose outdoor objects, boarding up windows and reinforcing doors, trimming trees and shrubs, and clearing gutters and downspouts. Consider investing in a generator for backup power. Create a hurricane kit including non-perishable food, water, medication, flashlights, batteries, and a first-aid kit.
FAQ 11: How long do hurricane watches and warnings typically last?
The duration of hurricane watches and warnings varies depending on the storm’s speed and trajectory. However, they typically last for several hours or even days. Continue monitoring the weather and following instructions from authorities until the alert is lifted.
FAQ 12: What happens after the hurricane passes?
After the hurricane passes, be aware of hazards such as downed power lines, flooding, and structural damage. Do not return to your home until authorities have declared it safe to do so. Report any damage to your insurance company and local authorities.
