Helene Makes Landfall as Devastating Category 4 Possibly Category 5 Hurricane

Hurricane Helene makes landfall as a devastating category 4 hurricane near Perry and Salem, Florida at approximately 11:15 PM EDT with maximum sustained winds of 140 mph and a central pressure of 938 mb. Hurricanes are ranked in a category scale from 1-5 based on the speed of the sustained winds within the inner eye wall of the storm.

  • Category 1: 74–95 mph, minimal damage 
  • Category 2: 96–110 mph, moderate damage 
  • Category 3: 111–129 mph, extensive damage 
  • Category 4: 130–156 mph, devastating damage 
  • Category 5: 157 mph or higher, catastrophic damage

The National Hurricane Center made remarks on their latest readings at 11:00 PM EDT that the estimation of 140 mph sustained eyewall winds may be conservative. Later data will be needed to obtain the exact wind speed and central pressure. NHC Weather drones have produced an unconfirmed report of 158 mph winds at or near the time of landfall. A few months from now/or sooner, when this is fully reviewed, it may potentially be bumped up to a category 5 hurricane.
