NWS Aberdeen SD issued a Dense Fog Advisory on Sept. 4, 2026, 9:45 a.m. MDT / 10:45 a.m. CDT, according to the National Weather Service's public alert record.
The alert states an effective time of Sept. 4, 2026, 9:45 a.m. MDT / 10:45 a.m. CDT, an onset of Sept. 4, 2026, 9:45 a.m. MDT / 10:45 a.m. CDT, and an expiry of Sept. 4, 2026, 10:45 a.m. MDT / 11:45 a.m. CDT. South Dakota spans two time zones and this alert may reach both, so each instant is shown in Mountain and then Central time; the office's own published offset is preserved in the machine-readable record.
The alert separately states that the hazard itself ends at Sept. 4, 2026, 10 a.m. MDT / 11 a.m. CDT. That is a different field from the message's expiry above and the two can differ.
Whether this alert is currently in effect is not stated in this text, deliberately: it depends on the time you are reading, so 605Buzz computes it from the expiry above each time the page is loaded rather than storing an answer that would go out of date without anyone noticing. The status shown at the top of this page is the computed one.
The issuing office classified this message as severity "Moderate", certainty "Likely" and urgency "Expected". Those are the National Weather Service's own categories, reproduced exactly; 605Buzz does not re-rank them or translate them into a scale of its own.
The recommended response type on the message is "Execute".
The alert names these areas: Traverse; Big Stone; Brown; Roberts; Walworth; Edmunds; Potter; Faulk; Grant; Hand. The National Weather Service zone codes are MNZ039, MNZ046, SDZ006, SDZ008, SDZ009, SDZ010, SDZ016, SDZ017, SDZ021 and SDZ037.
The issuing office's own summary line, as written on Sept. 4, 2026, 9:45 a.m. MDT / 10:45 a.m. CDT:
DENSE FOG ADVISORY WILL EXPIRE AT 11 AM CDT THIS MORNING
The full text of the alert as issued on Sept. 4, 2026, 9:45 a.m. MDT / 10:45 a.m. CDT, reproduced without changes:
Fog will continue for a few more hours. Dense fog, with visibilities to a quarter mile or less, is no longer expected.
The message carries no separate protective-action text.
This alert is a work of the United States federal government — the National Weather Service, part of NOAA — and is in the public domain; no copyright is claimed on it and none is asserted here. 605Buzz reproduces the record and does not add meteorological judgement. For live conditions and alerts, go to the National Weather Service.
605Buzz publishes alerts the National Weather Service gave a window of two hours or longer, and checks once a day. Short-notice warnings — including tornado and severe thunderstorm warnings, which the service typically issues for under an hour — are NOT carried here, so their absence from this site says nothing about whether one was issued. For those, and for live conditions, go to the National Weather Service.
