EMERGENCY Management

outdoor siren

In Hamilton County there are several outdoor warning sirens that can be activated rapidly during severe weather events, which are monitored closely by Hamilton County Emergency Management.

These sirens are activated when conditions exist that there is “imminent danger”, including, but not limited to a tornado sighting. Straight-line winds, microbursts and downbursts associated with severe thunderstorm activity are equally as dangerous as tornadic activity.

It is also important to know that outdoor warning sirens are variable in effectiveness according to wind direction and speed, placement of the siren, and whether someone is inside a building or outside. Subtitles

The sirens need to be tested to make sure that they are working properly. Hamilton County Emergency Management will resume testing the sirens now through October. This test will be done each Friday at 11 a.m. If inclement weather is in the area or the temperature is below 32 degrees the test will be performed the next Friday.

Severe weather can happen anytime, in any part of the country. Severe weather can include hazardous conditions produced by thunderstorms, including dangerous winds, tornadoes, large hail, flooding and flash flooding. To make sure you are always prepared:

  • Practice a severe weather plan for home and work

Be a Force of Nature by making sure that you and your family are prepared for severe weather. This includes creating a disaster supply kit and making sure that you can receive emergency messages.



A disaster supply kit is simply a collection of basic items your household may need in the event of an emergency.

Try to assemble your kit well in advance of an emergency. You may have to evacuate at a moment’s notice and take essentials with you. You will probably not have time to search for the supplies you need or shop for them.

This means having your own food, water and other supplies in sufficient quantity to last for at least 72 hours.
