Siren Testing The City will test tornado sirens periodically at noon.  The sirens will also sound in conjunction with the state-wide test on the first or second Tuesday in March.
Watches Thunderstorm or tornado watches are issued by the National Weather Service when conditions exist that could produce severe weather. Sirens will NOT be sounded. Be alert to weather conditions. Prepare to seek immediate shelter if it becomes necessary. Monitor local radio or television stations for emergency information.
Thunderstorm Warnings A severe thunderstorm warning is issued by the National Weather Service when high winds or large hail make conditions dangerous. Sirens will NOT sound. Take immediate shelter on the lowest level of the structure away from windows in a basement, interior hallway, bathroom or closet. Monitor local radio or television stations and remain in protected areas until notified by local media.
Tornado Warnings A tornado warning is issued by the National Weather Service when a tornado has been sighted or indicated on radar.  The siren will be sounded if a tornado or tornado producing storm is moving toward the Haven area.  In a power outage, emergency vehicles will provide street by street warning with sirens or public address systems. Sirens will sound a three (3) minute continuous blast. Take immediate shelter on the lowest level of the structure away from windows in a basement, interior hallway, bathroom or closet. Monitor local radio or television stations and remain in protected areas until notified by local media. Sirens will NOT sound an all-clear.  Sirens will only sound in the event of a warning or test. If outdoors when a tornado warning sounds, seek shelter indoors if possible.  Otherwise, lay flat in a ditch or depression away from trees or powerlines and cover your head. If driving a vehicle when a tornado warning sounds or you see a tornado, exit your vehicle and lay flat in a ditch, depression or other protected area.  If the tornado is over a half mile away you may drive at a right angle away from it if possible.
