Update: Severe Weather Drill Today is Cancelled

Update 10:45 a.m.: The Oakland County Homeland Security Division has cancelled the previously scheduled outdoor warning siren test today due to possible inclement weather.

"In an effort to ensure the outdoor warning sirens are affective and the public seeks shelter when activated, we will not conduct tests when possible storms are in the area," the department reported on its web site.

The next regularly scheduled siren test will be the first Saturday in May at 1 p.m.

8 a.m.: The National Weather Service is urging people to practice their tornado safety measures during a special drill Wednesday at 1 p.m.

The tornado drill is part of the National Weather Service's Severe Weather Awareness Week. The drill will be held throughout the state of Michigan.

According to a release from the organization, the National Weather Service will use its routine weekly test on NOAA weather radio all hazards to simulate an actual tornado waring.

Ready.Gov states people should do the following to prepare for a tornado:

• To begin preparing, you should build an emergency kit and make a family communication plan.
• Listen to NOAA Weather Radio or to commercial radio or television newscasts for the latest information. In any emergency, always listen to the instructions given by local emergency management officials.
• Be alert to changing weather conditions. Look for approaching storms.
• Look for the following danger signs:
  • Dark, often greenish sky
  • Large hail
  • A large, dark, low-lying cloud (particularly if rotating)
  • Loud roar, similar to a freight train.
  • If you see approaching storms or any of the danger signs, be prepared to take shelter immediately.
