Severe Weather Safety Rules
When preparing for severe weather, it is extremely important that you have multiple ways to recieve severe weather alerts from the National Weather Service. Some warning systems, such as cellphone towers, could be disabled by the severe weather itself, so it is best to have backup options. Here are the best ways to recieve warnings:
You will recieve the most critical weather warnings via Wireless Emergency Alerts (WEAs), accompanied by a loud siren. Ensure all emergency alerts are ON in settings. You should also download an app such as FEMA to recieve all weather alerts, rather than only high-end warnings.
NOAA weather radios are highly useful when severe weather is occuring, as it is activated for all important weather alerts (with non-critical alerts usually excluded). A high quality brand such as Midland is suggested, as most Midland radios can be set to only receive alerts for your specific county.
Tuning into a local weather or news station is a great way to stay alert during severe weather. Significant severe weather alerts will activate alerts on TVs as well.
Do NOT rely on tornado sirens during severe weather! Availability of tornado sirens and the requirements to activate them varies by county, and as a result, they are not reliable during severe weather.
What To Do When You Recieve an Alert
When you recieve a warning via one of the sources above, it is important to know how to treat each alert. WATCHES are issued when severe weather is possible in the next several hours. WARNINGS are issued when severe weather is imminent or occuring. Here is what common severe weather alerts mean and what you should do when you recieve the alert.
Severe thunderstorms (with damaging winds and/or large hail) are possible today.
OUTSIDE?
Closely monitor the weather for future alerts. Have a place to seek shelter quickly if severe weather develops.
Consider moving plans indoors if the forecast indicates that severe weather is highly likely at your location while you plan to be outdoors.
INSIDE?
Monitor the weather forecast in case a warning is issued. Know which parts of your structure are safest (avoid windows and higher floors).
Severe thunderstorms and tornadoes are possible today.
OUTSIDE?
Closely monitor the weather for future alerts. Have a place to seek shelter quickly if severe weather develops, and ensure this plan includes tornado procedures.
Consider moving plans indoors if the forecast indicates that severe weather is highly likely at your location while you plan to be outdoors.
INSIDE?
Closely monitor the weather forecast in case a warning is issued. If you own a NOAA weather radio, ensure it is set to alert mode.
Know what your tornado procedures are, and be prepared to move quickly into your tornado safe spot if a tornado warning is issued.
Storms capable of producing heavy rain and flooding are possible today.
OUTSIDE?
Monitor the weather forecast in case a flood warning is issued.
Consider postponing or cancelling outdoor plans, especially if thunderstorms are likely or you plan to be in a flood prone location.
INSIDE?
Monitor the weather forecast in case a flood warning is issued.
If you live in a flood prone area, or you are located near a river or stream, know your evaucauation route and be able to leave quickly if flooding occurs.
Severe thunderstorms (with damaging winds and/or large hail) are expected to begin shortly.
OUTSIDE?
Take shelter indoors immediately. Remain indoors until 30 minutes after you last hear thunder and after all warnings have expired.
Lightning, wind damage (such as falling trees), and large hail can cause severe injurty to those outdoors during a severe thunderstorm.
INSIDE?
Move away from windows onto the lowest level of your home. Injury is possible as a result of hail and falling trees, which will go through windows.
Destructive Warnings: Although rare, some severe thunderstorm warnings receive a DESTRUCTIVE tag. This means extreme winds or very large hail is expected, and this will trigger an emergency alert on your phone. These storms are very dangerous and should be treated like a Tornado Warning.
A tornado is occuring or imminent.
OUTSIDE?
Take shelter indoors IMMEDIATELY. Remain indoors until 30 minutes after you last hear thunder and after all warnings have expired.
When you seek shelter indoors, find a low-level interior room that offers the most protection from a tornado.
INSIDE?
Take shelter IMMEDIATELY in a basenent or an interior room on the lowest floor of a building. Use a tornado shelter if time allows (if you have a shelter).
If time allows, take protective supplies such as helmets and boots to your shelter, as well as other important things such as pets and critical documents.
PDS Tornado Warnings: Although extremely rare, some tornado warnings recieve a Particurally Dangerous Situation tag. This indicates a destructive and potentially deadly is actively occuring. For most people, this is a once in a lifetime event, and a PDS tornado warning indicates that you should be taking your tornado precautions very seriously and be preparing for a strong tornado impact.
Flash flooding is occuring or is expected to begin shortly.
OUTSIDE?
Move indoors or into a vehicle FIRST.
If you are in a low-lying or flood-prone location or are located near a stream, evacuate to higher ground.
TURN AROUND, DON'T DROWN when encountering floodwater over a road. If you cannot clearly see road paint under the water, the flooding could be several feet and easily overcome your vehicle. Sedans can be washed away in inches of water. DON'T drive over flooded roads.
INSIDE?
If you are in a low-lying or flood-prone location or are located near a stream, evacuate to higher ground.
Flash Flood Emergencies: Flash Flood Emergencies are the highest level of flood warning that the NWS can issue, and it is only issued when extreme flooding is ongoing. While these are extremely rare, recieving this alert means you should quickly evaucauate to higher ground and escape the incoming flood zone.
