inundation above ground level expected in low- lying areas
near shorelines and tidal waterways. For the High Surf

For the Beach Hazards Statement, from Sunday morning through
Sunday evening.
* IMPACTS...2 to 4 feet of inundation above ground level is
expected in some areas near shorelines and tidal waterways
resulting in an elevated threat of property damage. Flooding
will extend inland from the waterfront threatening some homes
and businesses. Numerous road closures and flooding of
vehicles will be possible. Vulnerable portions of NC-12 may be
inundated, especially around high tide. There is a possibility
of being stranded on Hatteras Island for multiple days. This
could be life threatening if you have an emergency. Dangerous
swimming and surfing conditions and localized beach erosion.
Rip currents can sweep even the best swimmers away from shore
into deeper water. Dangerous shore break can throw a swimmer
or surfer head first into the bottom causing neck and back
injuries. Strong longshore currents will create dangerous
swimming conditions.
* ADDITIONAL DETAILS...This has the potential to be a long
duration event bringing more significant ocean overwash
impacts to vulnerable oceanside areas through multiple high
tide cycles into next week. Minor soundside water level rises
will also be possible.

Internet connectivity at the time
Internet connectivity in United States dropped 33 minutes before this event, and stayed disrupted for about 1 hour.
From 18 Oct 2026 00:00 UTC to 18 Oct 2026 01:00 UTC. Detected by active probing — networks that stopped answering.
Internet outages have many causes — damaged cables, power failures, network maintenance and deliberate shutdowns among them. IODA detects the loss of connectivity and does not attribute it to anything. This is shown because it happened at the same time, not because one caused the other.
Measured by IODA, Georgia Institute of Technology.
