(CNN)With Hurricane Matthew ready to slam the United States in the next day or two, time is running out to get ready.
The deadly storm could make landfall Friday morning on Florida’s east coast, CNN meteorologist Dave Hennen said.
“That means people have less than 24 hours to prepare, evacuate and shelter. Having a plan in place could mean the difference between life and death.”
Matthew has already killed 10 people and carved a trail of destruction in several Caribbean countries. Next in its path: the Bahamas and United States.
Scott declared a state of emergency for the entire state. He warned that a direct hit by Matthew could lead to “massive destruction” on a level unseen since Hurricane Andrew devastated the Miami area in 1992.
Brevard County commissioners ordered one of the state’s first mandatory evacuations for residents of Merritt Island and other barrier islands.
Residents must leave starting at 3 p.m. Wednesday.
Palm Beach residents already cleared many grocery store shelves ahead of the storm.
