Why is a siren going off?
In short, it means that something life-threatening is happening and you should go indoors and get more information. The specific guidelines (tornado, hail ,wind, etc.) for sounding sirens varies by jurisdiction, so check with your local community to find out the specifics if you are interested. 2.
Damage (U.S.) Fatalities (U.S.) There have been 807 preliminary filtered reported tornadoes, and 649 confirmed tornadoes in the United States in 2023. Worldwide, 82 tornado-related deaths have been confirmed, 66 of them in the United States, eight in Myanmar, four in Indonesia, three in Turkey, and one in Saudi Arabia.
LINNEUS, Mo. —
Preliminary reports state an EF-2 tornado carved a nearly 12-mile track of damage in Linn County near Linneus, Missouri, on Saturday, May 6, 2023.
More recently, that focus has shifted eastward by 400 to 500 miles. In the past decade or so tornadoes have become prevalent in eastern Missouri and Arkansas, western Tennessee and Kentucky, and northern Mississippi and Alabama—a new region of concentrated storms. Tornado activity in early 2023 epitomized the trend.
The National Weather Service has determined two weather conditions for siren use. A steady tone, lasting 3 minutes, means a tornado watch or a severe thunderstorm watch. A wailing tone (6 sec. Hi/6 Low) lasting 3 minutes, means a tornado warning or severe thunderstorm warning.
The EWS sirens are tested annually during the month of August in a full-scale test. During the annual test, all 131 sirens are sounded at full volume for three minutes. The system is sounded at 12:00 pm and again at 12:30 pm to allow for emergency officials to test both the primary and backup activation points.
The 2023 tornado season is off to a windy start, with nearly 732 preliminary reports of tornadoes and 609 tornadoes already confirmed in 2023 within the U.S. as of May 18. There were 128 in January, 56 in February, 189 confirmed in March, 147 in April and 88 so far in May.
They are rare
EF-4 and EF-5 tornadoes are among the rarest cyclones on the planet.

Officially, the widest tornado on record is the El Reno, Oklahoma tornado of May 31, 2013 with a width of 2.6 miles (4.2 km) at its peak.
How do I know if a tornado is near me?
An approaching cloud of debris especially at ground level, even if a funnel is not visible; A loud roar - similar to a freight train - or a strange quiet occurring within or shortly after a thunderstorm. A change in the color of the sky. Debris dropping from the sky.
On May 3, 1999, strong tornadoes hit the Oklahoma City metro. Forty-six people died, and thousands lost their homes. The strongest tornado was an EF5 that tore through Moore. The total damage hit the billion-dollar mark.
What states don't have tornadoes? Alaska, Rhode Island, and Washington, D.C. rarely see tornadoes — they averaged zero tornadoes annually over the last 25 years, according to our analysis of NOAA data.
Worldwide, a total of 67 tornadoes have been officially rated F5/EF5: 59 in the United States, two each in France and Germany, and one each in Argentina, Australia, Canada, and Italy.
If a tornado appears stationary or is not moving left or right, there's a chance it's moving toward you. If this is the case, pull off the road and find a sturdy building to shelter in as quickly as possible.
1952 The Chrysler air raid sirens are the loudest sirens ever constructed, capable of producing 138 decibels at a distance of 100 ft (30 m).
Alert: A single tone signifying an emergency alert. This signal may be used to inform the community of an emergency or disaster, including a severe storm, tornado warning (not a tornado watch), earthquake, chemical hazard/hazardous material incident, extreme winds, or biological hazard.
The siren wail sound can be heard for an approximate distance of ½ mile.
Sirens are considered to be evil creatures who live in the sea. Generally, they are depicted as beautiful women with the tails of fish, but they can also be shown as scary, humanoid creatures with sharp teeth for tearing apart humans.
The sirens are powerful, but they have one weakness: if anyone hears them and survives, they will die.
What do I do if I hear a siren?
If you are in a car, park it, get out, and make your way as quickly as possible into any building you can enter. If you cannot do so, pull over, turn off the engine and ventilation system, and stay in the car.
Nevertheless, ground time can range from an instant to several hours, although the typical time is around 5 to perhaps 10 minutes. Supercell tornadoes tend to be longer-lived, while those pawned by squall lines and bow echoes may only last for a few minutes.
The strongest tornado was a low-end EF4 tornado that swept away homes on the west side of Keota, Iowa. Severe and tornadic weather also affected the Northeastern United States in the afternoon and evening of April 1, including a rare EF3 tornado that caused a death in Sussex County, Delaware.
There is no real evidence that tornadoes are happening more often. A lot more are being recorded now than in 1950, but a closer look at the data shows the increase is only in the weakest category, EF0. There's been no increase in stronger twisters, and maybe even a slight decrease in EF4s and EF5s.
EF-0: EF-0′s are the weakest tornadoes. An EF-0 tornado has max wind speeds of 65-85 mph.
The Met Office has predicted that 2023 will be hotter than 2022, and one of the warmest years on record. Temperatures are predicted to rise by between 1.08C and 1.32C, which will mark the 10th year in a row that global temperatures will reach at least 1C above average.
With the way the world is heading, expect a disaster a day by 2030, according to the UN. Climate change, the global pandemic and political destabilization are putting the world on a course toward daily catastrophe, according to a new United Nations report.
Earthquakes, however, can still claim a large number of lives. Whilst historically floods, droughts and epidemics dominated disaster deaths, a high annual death toll now often results from a major earthquake and possibly a tsunami caused by them.
F12 on the Fujita scale is equal to M1 (738 mph) on the Mach scale. Although the Fujita scale itself ranges up to F12, the strongest possible tornadoes are in the F5 range (originally estimated to be between 261 to 318 mph).
The state with the highest number of strong tornadoes per unit area is Oklahoma, with Cleveland County having the most tornadoes per square mile. States such as Oklahoma and Kansas have much lower population densities than Florida, so tornadoes may go unreported.
What tornado killed the most people?
The deadliest tornado of all time in the United States was the Tri-State Tornado on March 18, 1925 in Missouri, Illinois and Indiana. It killed 695 people and injured over 2,000.
Before a tornado hits, the wind may die down and the air may become very still. This is the calm before the storm. Tornadoes generally occur near the trailing edge of a thunderstorm and it is not uncommon to see clear, sunlit skies behind a tornado.
If you were picked up by a tornado, then the chances of survival are sadly slim. There are a handful of ways to not survive being picked up by the tornado. For one thing, if it lifts you high and lets you go, then the fall will likely kill you. Secondly, tornados pick up a lot of other things, not just humans.
WHAT WE FOUND. Panovich says it's a mere coincidence that the sky turns green before a tornado. He says because severe storms usually happen later in the day, the sun is at the exact right angle to create this color in the sky.
The Tri-State Tornado struck in 1925. The most powerful tornado to ever hit Missouri was the EF5 Tri-State Tornado, a twister that had winds of more than 300 mph. This tornado originally struck Missouri, but it also tore through parts of Illinois and Indiana.
In 1999, NWS recorded 1,343 tornadoes, a drop from 1,425 in 1998. Tornadoes resulted in 94 deaths–down nearly 30% from 1998's total of 130. Both years are significantly higher than the 10-year average for tornado deaths—58. Of the 94 fatalities, 39 were in permanent homes and 34 were in mobile homes.
The deadliest: The Tri-State Tornado (March 8, 1925)
The tornado was approximately . 75 miles wide and traveled a staggering 219 (newer research suggests it had a continual path of at least 174 miles) at a 59 mph pace. It caused 695 fatalities and destroyed more than 15,000 homes.
A civil defense siren, also known as an air-raid siren or tornado siren, is a siren used to provide an emergency population warning to the general population of approaching danger. It is sometimes sounded again to indicate the danger has passed.
In daylight the sounding of an air raid alarm is a signal for all traffic to stop and all persons to get indoors under cover. If you are not near a designated air raid shelter, select whatever place under cover is handy. Avoid getting near large windows.
Auditory hallucinations happen when you hear voices or noises that don't exist in reality. In some cases, they're temporary and harmless, while in others, they may be a sign of a more serious mental health or neurological condition. Auditory hallucinations have many possible causes.
What happens if a siren goes off?
When the siren sounds, a designated regional radio station will become the official emergency station. The public authorities will use the emergency station to inform you of ongoing events and dangers. They will also give you instructions and advice which must be followed.
The sirens are loud (130db at 100ft), but are not designed to be heard indoors. If you're within a couple of blocks of a siren, you may hear them indoors, but their intent is to be heard by people outside. Why did I hear sirens going off, but there is no tornado warning? Several possibilities.
There are two different tones used by Outdoor Warning Sirens: Attack: The signal for enemy attack is a rising and falling tone heard for 3 minutes. Civil Emergency: The signal for a civil emergency (such as a tornado) is a steady wail heard for at least 3 minutes.
When it comes to emergency vehicles' audible warning devices, there are three main styles of siren types: the wail, yelp, and the piercer or phaser. “The wail siren is the most common siren that people hear,” Montiero said.
The distinctive wailing sound of the tornado siren is designed to interject itself into whatever is going on so people are forced to pay attention to it and take action.
It's designed to terrify so that you won't be complacent and will take action. There is science involved with it so that it can wake sleeping people and come in at a range so it stands out form other noises. If it were pleasant sounding or at a different frequency or volume you wouldn't pay it any attention.
The siren has an output of 138 dB(C) (30,000 watts), and can be heard as far as 25 miles (40 km) away. In 1952, the cost of a Chrysler Air-raid Siren was $5,500 (Equivalent to $61,851 as in December 2022). The United States government helped buy sirens for selected state and county law enforcement agencies.
Strange Sounds in the House: Footsteps
Just not a ghost. If you have an unfinished attic, odds are those footsteps you hear come from some rowdy ducks, mice, a cat or even a wily raccoon. Maybe they are looking for food or – perhaps – to escape from becoming food.
Emergency Sirens and Firearms
Another sound that can damage your hearing are the emergency sirens that go wailing by. If they're stopped near you, the sound is around 120 dB. This can harm your hearing in just a few minutes!
Voices as you fall asleep or wake up – these might happen when you're half-asleep, because your brain is still partly in a dreaming state. The voice might call your name or say something brief. You might also see strange things. These experiences usually stop when you're fully awake.
What kills a siren?
Weaknesses. Bronze dagger and victim's blood – The only way to kill a siren is to stab it with a bronze dagger dipped into the blood of someone it has infected. The death of a siren releases its victims from its hold.
When a siren stops sounding, it does not mean that the potential weather threat has passed. Sirens are generally active for about three minutes, not for the duration of a threat. Stay inside until the threat has passed and media or local officials indicate it is safe.
Studies have recognized that sirens are a limited warning device and effective only at very short ranges and low speeds. At speeds above 50 mph, an emergency vehicle may "outrun" the effective range of its audible warning device.
