  "bodyMd": "**NWS Rapid City SD issued a Dense Fog Advisory** at 9:42 p.m. MST (10:42 p.m. CST) Nov. 12, 2026, according to the National Weather Service's public alert record.\n\nThe alert states that it takes effect at 9:42 p.m. MST (10:42 p.m. CST), gives the onset as 9:42 p.m. MST (10:42 p.m. CST) and expires at 11 a.m. MST (noon CST) Nov. 13. It may reach both of South Dakota's time zones, so each time is given in both.\n\nThe alert separately states that the hazard itself ends at 11 a.m. MST (noon CST), which can differ from when the message expires.\n\nWhether 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so it is computed from the expiry above each time the page is loaded, rather than stored as an answer that would go out of date without anyone noticing.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.\n\nThe issuing office classified this message as severity \"Moderate\", certainty \"Likely\" and urgency \"Expected\". Those are the National Weather Service's own categories, reproduced exactly, not re-ranked or translated into another scale.\n\nThe recommended response type on the message is \"Execute\".\n\nThe alert names these areas: Rapid City; Sturgis/Piedmont Foothills; Southern Meade Co Plains. The National Weather Service zone codes are SDZ026, SDZ072 and SDZ073.\n\nThe issuing office's own summary line, as written at 9:42 p.m. MST (10:42 p.m. CST) Nov. 12:\n\n> DENSE FOG ADVISORY IN EFFECT UNTIL 11 AM MST FRIDAY\n\nThe full text of the alert as issued at 9:42 p.m. MST (10:42 p.m. CST), reproduced without changes:\n\n> \\* WHAT...Visibility one quarter mile or less in dense fog.\n>\n> \\* WHERE...Southern Meade Co Plains, Sturgis/Piedmont Foothills, and\n> Rapid City.\n>\n> \\* WHEN...Until 11 AM MST Friday.\n>\n> \\* IMPACTS...Low visibility could make driving conditions hazardous.\n\nThe protective-action text the issuing office attached, reproduced without changes:\n\n> If driving, slow down, use your headlights, and leave plenty of\n> distance ahead of you.\n\nThe National Weather Service superseded this message at 10:58 a.m. MST (11:58 a.m. CST) Nov. 13 with a later one. This article records the message as issued.\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. The alert is reproduced without added meteorological judgement. For live conditions and alerts, go to the [National Weather Service](https://www.weather.gov/).\n\nOnly 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](https://www.weather.gov/).",
