A state of emergency has been declared for Onslow County, which holds Jacksonville. Onslow officials said in a press release, “Hurricane Florence has recently upgraded from a Category 3 to a Category 4 hurricane and is projected to make landfall by Thursday night or early Friday morning. Onslow County Board of Commissioners has decided that due to the severe nature of the storm they are declaring a State of Emergency, and encouraging all Onslow County residents to evacuate and seek shelter west of Greensboro. In a meeting with Onslow County partners, government officials also decided that they would activate emergency shelters within the county. These shelters will act as a last resort shelter for residents who cannot evacuate the county.”

The Jacksonville website said that, as of early on September 12, 2018, there were voluntary evacuations for Jacksonville. “The Mayor of Jacksonville has announced a voluntary evacuation of the City and strongly urges residents and visitors to seek safe shelter in a community outside of the area. Hurricane Florence is predicted to be a significant storm with wind speeds of 140 mph and record setting rainfall. Storm surge is expected to be higher than ever experienced in Jacksonville,” the release said. “For those who remain in Jacksonville, a curfew will be issued so that emergency personnel can safely maneuver. Sightseeing after the storm is strongly discouraged. Those who stay should be prepared for a 3 to 4 day event. To prepare, you should:

  • have a supply of non-perishable food items and water
  • secure valuable documents in a waterproof container
  • expect to be without electricity for weeks
  • secure windows and outdoor furniture

City operations for non-essential services will close at noon on Wednesday, September 12, 2018.”

Onslow County reported, “Onslow County Government has officially declared a mandatory evacuation for all residents in the unincorporated areas of Onslow County.”
