How to determine whether to shelter in place or evacuate based on storm intensity and official guidance
In severe storms, decision making hinges on intensity, official advisories, building safety, and personal circumstances, guiding households toward sheltering in place or orderly evacuation with practiced plans and trusted information.

When a forecast warns of a powerful weather system approaching your area, the first step is to understand the difference between sheltering in place and evacuating. Sheltering in place means staying indoors, securing your immediate environment, and riding out the event with minimal exposure to dangerous conditions. Evacuation involves leaving your home or workplace to reach a safer location, often designated by authorities or your personal safety plan. The choice depends on storm intensity, anticipated impacts, and the reliability of shelter options nearby. Officials provide color-coded alerts, evacuation orders, and route advisories that reflect current conditions. Listening to licensed meteorologists and emergency managers helps you align your actions with real-time risk assessments rather than assumptions.
Practical preparation improves the odds of choosing correctly when seconds matter. Before a storm, create a simple, repeatable plan that explains when to shelter and when to exit. Identify safe rooms or interior spaces with minimal windows and sturdy doors, and assemble disaster kits containing water, food, lighting, batteries, a first aid kit, medications, and important documents. Know multiple routes to safe zones, including alternatives in case primary roads are blocked. Establish a family communication protocol, designate a meeting place, and assign responsibilities so each member understands their role. Regular drills build muscle memory, reducing indecision when official guidance changes rapidly.
Use official guidance and local conditions to decide
The core decision rests on storm intensity, not fear or rumor. A weak storm may still require shelter if you live in a flood-prone or high-wind area, while a stronger system could push you toward evacuation if local shelters have capacity and reliable access routes exist. Official guidance comes from national and local authorities who use criteria such as wind speeds, rainfall totals, and projected surge or flood risks. They may issue evacuation orders, curfews, or shelter-in-place advisories that reflect the current threat and the practicality of staying put. Continuous updates through trusted channels ensure your decision aligns with the evolving situation.

Weather models provide probabilistic forecasts, but conditions can shift quickly. Rely on official messages that translate data into concrete actions, like “shelter in place now” or “evacuate via designated routes.” If authorities urge evacuation, follow the instructions promptly and avoid improvising. Check whether your intended safe destination is accessible, ADA accommodations exist if needed, and whether there is power, water, and medical support there. Avoid delays caused by gathering nonessential items; prioritize ensuring essential safety equipment, medications, and important documents stay with you. Community nets and emergency alert apps can offer critical, time-sensitive updates.
Consider personal needs and housing when choosing shelter
When the call is to shelter, elevate your safety by preparing the space with the best possible protection. Move people away from exterior walls, lock doors, and cover windows if possible. Turn off gas and electricity at main switches if advised, and unplug electrical devices to prevent surges. Keep pets indoors and create a quiet, darkened area that reduces stress and exposure to loud storms. Maintain a small emergency kit within reach, including flashlights, a battery-powered radio, and a basic medical supply. Ensure phone batteries stay charged, and designate a communication point inside the shelter where everyone can regroup after the worst passes.

If evacuation is ordered, act decisively to reduce risk and confusion. Gather your kit, lock up essential papers, and bring enough supplies for the time you expect to be away, plus extra for potential delays. Follow official routes even if you know shortcuts, because road closures and hazards can appear suddenly. Leave water taps turned off, minimize use of fuel, and avoid blocking access for emergency responders. If you cannot evacuate by vehicle, know your alternatives, such as sheltered public facilities or travel with neighbors. After departure, inform a trusted contact about your location and status.
Plan for safe movement and communication during crises
Household factors matter in the shelter decision. Large families or those with vulnerable members may benefit from staying in a prepared interior space rather than braving roadways during a surge. Homes with basements should consider whether a higher floor or interior room is safer in flood-prone zones. People requiring medical devices or electricity for life-sustaining equipment should plan power options and backup communication. Pets, seniors, and small children add layers of complexity, so plans should accommodate their safety with clear, practiced routines. Always balance the emotional toll of staying with the physical risk of moving through dangerous weather.
Community support and neighborhood dynamics influence outcomes too. Some neighborhoods have predefined shelter locations or mutual aid arrangements that reduce evacuation pressures. Local responders may set up temporary medical centers or distribution sites for food and water during long events. Networking with neighbors to share information can fill gaps when official channels are delayed. It’s wise to know which routes are passable for wheelchairs or strollers and to plan for the needs of people who cannot drive. Informed, cooperative decisions strengthen resilience in households and communities.

Rehearse your plan and learn from every weather event
Communication reliability is crucial as storms intensify. Radios, phones, and internet access can fluctuate, so establish multiple channels for updates. If you stay home, keep a family contact number and a local emergency number handy, and confirm meeting points with everyone. If you evacuate, share your route and estimated arrival time with a trusted person who can monitor updates. Emergency alerts, sirens, and official broadcasts should be treated as authoritative, not optional. Weather-related misinformation travels quickly; verify any advice using official sources before acting. Clear, calm communication reduces confusion and speeds coordinated responses.
In the heat of the moment, prioritize safety over convenience. Individuals should avoid attempting to drive through flooded roads or blocked highways, as many fatalities occur during misjudged crossings. If you are in a tall building during a tornado warning or severe wind event, move away from windows and seek interior spaces on lower floors. For power outages, conserve energy by turning off nonessential equipment and using flashlights rather than candles to prevent fire hazards. Practice situational awareness, keep essential items close, and maintain a disciplined, patient mindset that prioritizes everyone’s safety.
After a storm passes, review what worked and what could improve your plan. Debrief with family members to identify gaps in sheltering or evacuation procedures, such as access routes, communication timing, or kit contents. Update contact lists, inventory essential supplies, and verify that medications and documents remain accessible. If you evacuated, gather at-home safety checks, inspect structural integrity, and confirm that utilities are restored safely. Use these lessons to refine your preparedness routine, ensuring you’re better equipped for the next incident. Documentation of what happened supports future decision making.
Finally, cultivate a culture of ongoing readiness. Regularly update your weather apps, refresh batteries, and rotate food and water supplies to maintain freshness. Practice short drills on deciding between shelter and evacuation, then vary scenarios to reflect different threat levels. Engage trusted neighbors in shared preparedness tasks, such as code words, check-in times, or mutual aid strategies. By treating severe weather planning as a continuous process rather than a one-off task, families gain confidence, reduce risk, and recover more quickly when storms occur.
