Secure loose outdoor items
The NWS says high winds can blow objects around and pose a significant threat to your safety.
Know if you are in a flood-prone area
If you are in a flood-prone or low-lying area, get to higher ground immediately when water starts to rise.
Know your evacuation zone
Find out whether you live in a hurricane evacuation area by contacting your local government or emergency management office.

Know your safe place and how you get alerts
Your safe place is a basement, safe room or an interior room on the lowest floor of a sturdy building, away from windows. Tornado warnings are sent as Wireless Emergency Alerts.
Go to your safe place and stay away from windows
Move to your basement, safe room or an interior room on the lowest floor of a sturdy building. Avoid windows. If time allows, take pets with you.
Leave a mobile home for a sturdy building
A mobile home or tent is not safe in a tornado. Seek a sturdy building immediately when a tornado approaches.

Check road conditions before you leave
Check 511 for traffic, road conditions and restrictions before you leave, and share your timetable and your primary and alternate routes. In a winter storm warning, delay travel until conditions improve.
Avoid going outdoors in a wind chill warning
A wind chill warning means dangerously low wind chill is expected, which can cause frostbite and hypothermia. Avoid going outdoors if possible.
Put a winter survival kit in your car
Include a phone and charger, blankets or sleeping bags, a flashlight with extra batteries, a first aid kit, high-calorie food, extra dry clothing and a shovel. Keep the gas tank near full.

Know if you are in a flood-prone area
If you are in a flood-prone or low-lying area, get to higher ground immediately when water starts to rise.
Evacuate when water starts to rise
Evacuate immediately when water starts to rise. If told to leave, go right away. Follow orders from local emergency management.
Turn around, don’t drown
It is never safe to drive or walk into flood waters. Six inches of fast-moving water can knock over an adult, and twelve inches of rushing water can carry away most cars. Never drive around the barriers blocking a flooded road.
Check on people at risk, especially without air conditioning
The NWS advises checking in with friends and relatives who are at higher risk, especially if they do not have air conditioning.
Never leave a child or pet in a parked car
Leaving a child, disabled person or pet locked in a car is never safe. The NWS warns that children can die in a hot car within 10 minutes.

Hurricane events and tracking →Common questions about severe weather alerts
What is the difference between a weather watch and a warning?
A watch means a hazard is possible, so get ready. A warning means it is happening or imminent, so act now. An advisory is a less serious condition that can still cause inconvenience or risk. A warning is more serious than a watch or an advisory.
What types of severe weather warnings are there?
The National Weather Service issues warnings for tornadoes, severe thunderstorms, floods and flash floods, winter storms and blizzards, ice storms, extreme heat, high wind, hurricanes and tropical storms, and fire weather (red flag warnings). Each type has its own page with every active alert and what to do.
What is the most serious weather alert?
A warning is the more serious level, and the National Weather Service reserves special wording for the worst cases. A Tornado Emergency means a confirmed large tornado is moving through a populated area and there is an exceptional threat to life. Whatever the alert, read the text for what, where and when.
How do I get severe weather alerts on my phone?
Wireless Emergency Alerts need no signup and are free. They are sent automatically to capable phones during an emergency, and Government Alerts are on by default on iPhone. For alerts for your own ZIP code, use Near Me.
Where can I see a map of severe weather alerts?
The map at the top of this page shows where alerts are active now. The alerts page lists every active National Weather Service alert by state and by type.
