  "bodyMd": "**NWS Sioux Falls SD issued a Special Weather Statement** on Oct. 29, 2026, 3:47 a.m. MDT / 4:47 a.m. CDT, according to the National Weather Service's public alert record.\n\nThe alert states an effective time of Oct. 29, 2026, 3:47 a.m. MDT / 4:47 a.m. CDT, an onset of Oct. 29, 2026, 3:47 a.m. MDT / 4:47 a.m. CDT, and an expiry of Oct. 29, 2026, 6 a.m. MDT / 7 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.\n\nWhether 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so 605Buzz computes it from the expiry above each time the page is loaded rather than storing an answer that would go out of date without anyone noticing.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.\n\nThe issuing office classified this message as severity \"Moderate\", certainty \"Observed\" 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.\n\nThe recommended response type on the message is \"Execute\".\n\nThe alert names these areas: Lyon; Osceola; Sioux; O'Brien; Plymouth; Cherokee; Woodbury; Rock; Dixon; Dakota; McCook; Minnehaha; Hutchinson; Turner; Lincoln; Bon Homme; Yankton; Clay; Union. The National Weather Service zone codes are IAZ001, IAZ002, IAZ012, IAZ013, IAZ020, IAZ021, IAZ031, MNZ098, NEZ013, NEZ014, SDZ061, SDZ062, SDZ065, SDZ066, SDZ067, SDZ068, SDZ069, SDZ070 and SDZ071.\n\nThe issuing office's own summary line, as written on Oct. 29, 2026, 3:47 a.m. MDT / 4:47 a.m. CDT:\n\n> AREAS OF DENSE FOG MAINLY NEAR RIVER VALLEYS THIS MORNING\n\nThe full text of the alert as issued on Oct. 29, 2026, 3:47 a.m. MDT / 4:47 a.m. CDT, reproduced without changes:\n\n> Areas of fog have developed early this morning, with dense fog\n> confined to areas mainly near river valleys. Though fog may spread\n> a bit farther, the greatest chance of dense fog will continue to\n> be along and near river valleys through the morning commute\n> Thursday. Make sure to use your low beam headlights when driving\n> in fog and consider leaving extra time to get your destination.\n> Any fog should lift entirely by 10 am or shortly afterwards.\n\nThe message carries no separate protective-action text.\n\nThis 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](https://www.weather.gov/).\n\n605Buzz 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](https://www.weather.gov/).",
