PREPARATION FOR SEVERE WEATHER
Strong thunderstorms and tornadoes occur in many parts of the world, but are most common in the United States. In an average year, 800 tornadoes are reported nationwide. An average of 80 deaths and more than 1,500 people are reported injured in the U.S. every year. A tornado is defined as a violently rotating column of air extending from a thunderstorm to the ground. The most violent tornadoes are capable of widespread destruction with wind speeds of 250 mph or more. Tornadoes are most likely to occur between 3PM and 9 PM, but have occurred during all hours of the day and night. The "average" tornado moves from southwest to northeast, but tornadoes can move in any direction. The average forward speed for a tornado is 30 mph, but can vary from nearly stationary to 70 mph. Please be aware of the following types of severe weather advisories issued by the National Weather Service:
A SEVERE THUNDERSTORM WATCH
Severe thunderstorms are possible in your area. Thunderstorms are defined as severe if they produce winds in excess of 58 mph, and/or produce hail ¾ of an inch in diameter or larger.
A SEVERE THUNDERSTORM WARNING
Severe thunderstorms are occurring, or imminent. Keep in mind that tornadoes occasionally develop in areas where severe thunderstorm watches or warnings are in effect. Remain alert to signs of an approaching tornado and seek shelter if threatening conditions exist.
A TORNADO WATCH
Tornadoes are possible in the area. Remain alert for approaching storms. Be prepared to move to a safe location.
A TORNADO WARNING
A tornado has been sighted, or is imminent. If a tornado warning has been issued for your area, move to your pre-designated place of safety. If you are on campus when a tornado warning has been issued, you should move to the lower level of whatever building you are in. DO NOT go outside to check the weather. If an underground area is not available, move to an interior room or hallway on the lowest floor. Crouch down against a wall or get under a sturdy piece of furniture. Auditoriums, gymnasiums, and other structures with high, wide-span roofs do not offer good protection. Stay away from windows and exterior doors. If you are outdoors, DO NOT attempt to outrun a tornado in a bus, truck, or car; instead, abandon it for a strong building. If you are on the road, remember that overpasses offer little protection from tornadoes and should not be used as shelters. If caught in the open, take cover in a ditch or low spot. Remember, this will not provide the same protection as a sturdy building. Occasionally, tornadoes develop so rapidly that advance warning is not possible. Remain alert for signs of an approaching tornado. FLYING DEBRIS FROM TORNADOES CAUSES MOST DEATHS AND INJURIES. (SOURCE: NATIONAL WEATHER SERVICE) If stormy weather, listen to your radio and/or television station for weather service reports. Area radio stations include (not an all inclusive list):

Below is a list of other helpful web sites with information about severe weather, lightning, thunderstorms, hail, high winds and driving safety: National Weather Service; Iowa Department of Transportation; State of Iowa Weather; Weather Driving Safety Tips. If the storm increases in intensity, listen to your radio (portable transistor is best). The Weather Service will report if this area is under a severe thunderstorm or tornado watch. A watch means that conditions exist that a severe storm or tornado are possible. A warning means that a severe storm or tornado has been sighted. If a warning is issued for Grinnell and Poweshiek County, seek appropriate shelter as noted below. If a tornado is sighted in the area, warning sirens will sound. The sirens will make a long, continuous, loud sound. When you hear it during a storm, do not hesitate. Take shelter immediately. (Note: The sirens are tested at 9:00 a.m. each Thursday).
DURING A TORNADO WARNING
- Go to the lowest floor of any building you are in, such as a basement or dormitory pit. Go to interior spaces or rooms that face east, preferably north and East. (Rooms facing north and east are usually safer than those that face south and west.)
- Get into a room or area without windows. If this is not possible, stay away from the windows or exterior walls. Get behind/under a heavy piece of furniture or object to protect against flying debris.
- Avoid corridors, particularly those facing west or south. If you have to take shelter in one try to stay away from the glass areas.
Avoid any building with a long-span flat roof or large open spaces in its interior if possible. If in a car and there is a tornado warning, get out of the car and seek shelter in the lowest level of a nearby building. If there is not enough time, lie flat in a ditch or other depression off the roadway. Don't call the College switchboard, Facilities Management, Security Department, or the City Police or Fire during a tornado warning period unless there is a clear emergency. These lines should be kept open for emergency purposes only.
