| TORNADO WATCH | This means that conditions are such that storms capable of producing a tornado may develop in the next few hours. |
| TORNADO WARNING | This means that either a tornado has been sighted or that it is highly probable that one will develop. The warning will be signaled by the storm warning sirens. |
DURING A TORNADO WATCH: Move smaller objects indoors. Grills, bicycles, patio furniture, and lawn mowers can become missiles in tornadic winds and cause additional damage. Stay close to your TV or radio to see if a tornado warning is imminent. Go to a shelter when it begins to storm--don't wait until the sirens are sounded.
TORNADO TAKE-COVER SIGNAL is a 3 to 5 minute wail on the storm sirens. This signal will be sounded on the large sirens placed in the University Apartments area, on the main campus, and those installed throughout the City of Stillwater. (If the sirens sound again, it is further warning--NOT all clear.)
If local radio is available, keep tuned to KOSU-FM (91.7 MHz), KSPI-FM (93.7 MHz), KVRO-FM (98.1 MHz) or KGFY-FM (105.5 MHz) for storm details. The Stillwater Emergency Communications Center can interrupt the audio of these radio stations to broadcast warnings. They can also interrupt the audio of most cable (not satellite) TV channels. The "All Clear" signal is given over FM radio and NOT the storm sirens. Try to remain calm at all times.
In Spring and early Fall, when tornados are most likely to occur in Oklahoma, be aware of your surroundings and the current environment and the different possibilities that may occur. Then make appropriate decisions based on what is happening or has the potential to happen. Here is a likely scenario:
Based on your assessment of the environment and the possibility of severe weather, here are actions you can take:
Everyone must assess for themselves what their risk is. In this age of increasingly instant communication, it is possible to have enough information to be aware of the presence of severe weather.
Have you given any thought about what to do in case the tornado warning sirens sound during office hours? Does your office staff know where to go? What should instructors tell their students?
When the fire alarm sounds, everyone knows to immediately get out of the building. When the storm warning sirens sound, it is best NOT to leave the building. Obviously, it is better to seek shelter in a basement. If the building you are in has no basement, or if there is no nearby building with a basement, go to the lowest floor and get in a small interior room or hallway. Stay away from glass and exterior walls; put as many walls between you and storm as you can. (If you go outside to watch the show, you might become part of the cast.)
Please share these facts with your office staff and others in your department or division. Encourage everyone to make plans for where they will go when severe weather strikes during class or office hours. A good idea would be to have a drill during the next regularly scheduled storm siren test. (Usually the first Tuesday of each month at 11:30 a.m.) The Environmental Health & Safety Department encourages you to take responsibility for plans in your area.
If you are on campus during a normal work day, the best places to seek shelter are in buildings with basements.
These buildings have basements: Ag Hall, Architecture, ATRC, Bennett Hall, Business,
Classroom, Colvin, Cordell, Engineering North & South, Gallagher-Iba,
Human Environmental Science, Iba Hall, Library, Life Science East & West, Math
Science, North Murray, Parker Hall, Physical
Sciences, Scott Hall, Seretean, Small Grains, Stout Hall, Student Health, Student Union,
USDA, Wellness Center, Wentz Hall,
and Willard.
(Note that some of these basements are quite small.)
If the building you are in has no basement, go to the ground floor and get in an interior (windowless) room or hallway. It is generally too risky to go to another building once the sirens have sounded.
Handicapped persons who are mobility impaired must also make plans. If a power outage occurs during severe weather, elevators may not work. Always go to a small interior room or closet; stay away from windows and exterior walls. Plan ahead and become aware of accessible shelters on campus.
When the alarm is sounded (or you hear a warning announcement) grab your pillow and go to the lounge on your floor (don't forget your shoes). Most floor lounges are in the center of the building and therefore are windowless. Know ahead of time what your residence hall's severe weather plan is for your floor. If you are on a floor in the upper half of a high-rise building, the plan may call for you to go to a designated lounge on a lower floor. Severe weather could result in the interruption of electrical power; for this reason it's best to avoid the use of elevators. Some residence halls have large glassed-in lobbies; these areas should be avoided because of the glass that could be blown in by a storm. Follow the instructions of hall personnel and don't leave the building until the "all-clear" is given.
When the storm warning sirens sound, it is best NOT to leave your home unless better shelter is just a minute or two away. If your house does not have a basement, go to the lowest floor and get in a small interior room or hallway. (If you have time, you might get in the bathtub and pull a mattress over the tub.) Stay away from glass and exterior walls.
Some of you may remember an old rule that said opening windows would "equalize pressure." This is iffy at best, and a waste of precious time. Leave the windows alone and get as far away from them as you can. If you are in a mobile home, seek shelter elsewhere. Mobile homes are notoriously unstable and are frequently destroyed during tornados. If there is no storm shelter nearby, go outside and find a ditch or depression and lie flat, face down, with your hands on the back of your head.
If you are in a gymnasium, auditorium, or theater (most likely full of people), follow the instructions of those in authority and don't run in panic. Large open-span areas such as these are subject to collapse, so it is best to seek shelter in a hallway or small room. This is also true of large stores like Wal-Mart or supermarkets. In those situations, if there is no time to seek better shelter, go to the very back of the store--away from any large areas of glass--crouch down, and cover your head.
If you are in a motor vehicle, don't try to out-run the storm. Tornados do not travel in a predictable direction, and some are faster than others. Don't stay in your vehicle-- it's worse than a mobile home. In addition, driving in a city is very dangerous because everyone will be ignoring traffic laws in a rush to get to shelter. If there is no nearby building, find a ditch or depression and lie flat, face down, with your hands on the back of your head.
If you see an overpass nearby, DO NOT consider it as shelter. Overpasses are very dangerous because they offer no protection from the blast of flying debris in the violently shifting winds of a tornado. Read NOAA's report on Highway Overpasses as Tornado Shelters (http://www.srh.noaa.gov/oun/papers/overpass.html) for more information.
The time to plan for tornados is now. Department heads and their employees should seek out the best place for everyone to take shelter if the storm happens during working hours. Everybody should make similar plans at home. Make sure you have a portable radio and flashlight (with extra batteries), a first-aid kit (along with any necessary medications), sturdy shoes and work gloves, bottled water, and canned food (don't forget the can opener).
Tornado shelters can save lives. Designs and engineering drawings are available from the Wind Engineering Research Center, (http://www.wind.ttu.edu) at Texas Tech University. Just call 1-888-565-3896 and ask for the booklet, "Taking Shelter From the Storm" (FEMA 320), which is free of charge. This phone number was established exclusively for requests for this booklet. Just follow the instructions to leave your name and address and you will receive a copy of FEMA 320 in the mail.
For added protection, a qualified contractor can fasten down the roof of your house with metal hurricane clips or straps attached to the top plates or beams. You can also download plans for a tornado room from the Federal Emergency Management Agency (http://www.fema.gov/fima/tsfs02.shtm), 500 C St. SW, Washington DC 20472, or call FEMA at 800-480-2520. They also have a booklet available on "Building Performance During Hurricane Andrew."
As a service to the non-campus general public, three campus buildings are available as tornado shelters. If severe weather threatens the Stillwater area after regular office hours, these buildings will be unlocked by OSU Police.:
(Don't wait until the storm sirens sound to go to these shelters. Monitor local radio & TV reports and go to the shelters when it begins to storm.)
AG HALL (corner of Farm Road and Monroe): The south entrance at the east end is wheelchair accessible.
ENGINEERING SOUTH (east of the Library): This basement is wheelchair accessible, but only by elevator.
STUDENT UNION (Use the Hotel or Parking Garage entrance after 5:00 p.m.): The entrance from the center-level parking garage is wheelchair accessible.
All storm sirens in the city of Stillwater (including the OSU campus) are tested on the first Tuesday of every month at 11:30 in the morning. The test is conducted by the Stillwater Emergency Coordination and Communications Department. If it is cloudy or rainy the test is postponed until Thursday morning to avoid any confusion. If the weather still won't permit testing on Thursday the test will be conducted the following Tuesday, when the equipment will be tested without sounding the sirens.
