NWS Aberdeen SD issued a Special Weather Statement at 11:57 a.m. MDT (12:57 p.m. CDT) Oct. 31, 2026, according to the National Weather Service's public alert record.
The alert states that it takes effect at 11:57 a.m. MDT (12:57 p.m. CDT), gives the onset as 11:57 a.m. MDT (12:57 p.m. CDT) and expires at 2 p.m. MDT (3 p.m. CDT). It may reach both of South Dakota's time zones, so each time is given in both.
Whether this alert is currently in effect is not stated in this text, deliberately: it depends on the time you are reading, so it is computed from the expiry above each time the page is loaded, rather than stored as an answer that would go out of date without anyone noticing.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 "Observed" and urgency "Expected". Those are the National Weather Service's own categories, reproduced exactly, not re-ranked or translated into another scale.
The recommended response type on the message is "Execute".
The alert names these areas: Corson; Campbell; McPherson; Brown; Marshall; Roberts; Walworth; Edmunds; Day; Dewey; Potter; Faulk; Codington; Grant; Sully.

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. The alert is reproduced without added meteorological judgement. For live conditions and alerts, go to the National Weather Service.
Only alerts the National Weather Service gave a window of two hours or longer appear here, checked 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 here says nothing about whether one was issued. For those, and for live conditions, go to the National Weather Service.
