Alabama Gov. Kay Ivey issued a statewide state of emergency today in preparation for the approach of Hurricane Michael.

The storm is expected to cause wide-spread power outages, high winds and heavy rain in Alabama. Flash floods and tornadoes are possible. Parts of the state are under tropical storm watches or warnings.

The state of emergency went into effect at 3 p.m.

Ivey urged south Alabamians to prepare for the emergency immediately.

"Tomorrow we will start seeing the effects of Michael and those in its path will need to take shelter by tomorrow evening," the governor said in a press release. "Please stay weather aware today and tomorrow for any forecast changes. Most importantly, heed all warnings and instructions from local authorities."

The state of emergency declaration activates the Alabama emergency operations plan.

Alabama Emergency Management Agency Director Brian Hastings said uncertainty about the path of the storm was a concern.

"I am concerned about the cone of uncertainty as Hurricane Michael is leaning west today," Hastings said. "Residents and businesses in coastal Alabama must be vigilant and closely monitor the storm's path and be prepared for a major hurricane."
