A stronger atmospheric river continues to move over the panhandle
Thursday evening, lasting through Friday morning. Multiple waves
moving up will bring persistent moderate to heavy rain for much of
the southern half of the panhandle, with the heaviest rain expected
through Thursday night. Elevated gusty winds are expected alongside
this heavier rainfall, with the strongest winds expected Thursday
night. Prolonged periods of moderate to heavy rain will produce
significant river rises with the potential for at least minor
flooding. Gusty winds alongside the long duration heavy rainfall will
bring a possibility of isolated landslides.

Internet connectivity at the time
Internet connectivity in United States dropped 44 hours after 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.
