Hurricane Michael has now strengthened into Category 4 as it speeds towards Florida Panhandle.
It upgraded from category 3 to 4, hours before making an expected landfall around Wednesday afternoon, reported news agencies.
Following its strengthening, Hurricane Michael will now be one of the strongest storms to hit Florida Panhandle in recent history.
Terming it as “extremely dangerous”, the National Weather Service has deemed the storm as life-threatening.
Torrential rainfall is expected along the northeastern Gulf Coast.
The advisory comes after US President Donald Trump declared a state of emergency in Florida by extending federal assistance to supplement state and local response efforts due to the emergency conditions resulting from Michael.
The statement further said that Thomas J McCool was named as the Federal Coordinating Officer for recovery operations in the affected areas.
Trump on Tuesday warned residents about the hurricane and requested them to listen to local officials and stay safe.
The dreaded storm has already wreaked havoc in Central America, where 13 people have been reported dead. Parts of western Cuba, where the hurricane made the landfall, was forecast to receive up to a foot of rain.
