  "bodyMd": "**NWS Rapid City SD issued a Red Flag Warning** on Oct. 23, 2026, 10:42 a.m. MDT / 11:42 a.m. CDT, according to the National Weather Service's public alert record.\n\nThe alert states an effective time of Oct. 23, 2026, 10:42 a.m. MDT / 11:42 a.m. CDT, an onset of Oct. 23, 2026, 11 a.m. MDT / 12 p.m. CDT, and an expiry of Oct. 23, 2026, 11 p.m. MDT / Oct. 24, 2026, 12 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\nThe alert separately states that the hazard itself ends at Oct. 23, 2026, 11 p.m. MDT / Oct. 24, 2026, 12 a.m. CDT. That is a different field from the message's expiry above and the two can differ.\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so 605Buzz computes it from the expiry above each time the page is loaded rather than storing an answer that would go out of date without anyone noticing.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 \"Severe\", 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.\n\nThe recommended response type on the message is \"Prepare\".\n\nThe alert names these areas: Northern Foot Hills; Butte County Area; Northern Campbell; Southern Campbell; Crook County Plains; Weston County Plains; Wyoming Black Hills. The National Weather Service zone codes are SDZ323, SDZ327, WYZ314, WYZ315, WYZ316, WYZ317 and WYZ318.\n\nThe issuing office's own summary line, as written on Oct. 23, 2026, 10:42 a.m. MDT / 11:42 a.m. CDT:\n\n> RED FLAG WARNING REMAINS IN EFFECT UNTIL 11 PM MDT THIS EVENING\n\nThe full text of the alert as issued on Oct. 23, 2026, 10:42 a.m. MDT / 11:42 a.m. CDT, reproduced without changes:\n\n> ...RED FLAG WARNING REMAINS IN EFFECT UNTIL 11 PM MDT THIS EVENING\n> DUE TO GUSTY WINDS AND LOW RELATIVE HUMIDITY FOR NORTHERN FOOT HILLS,\n> BUTTE COUNTY AREA, NORTHERN CAMPBELL, SOUTHERN CAMPBELL, CROOK COUNTY\n> PLAINS, WESTON COUNTY PLAINS, AND WYOMING BLACK HILLS...\n>\n> .Warm temperatures, humidities as low as 13%, and southwest winds\n> gusting to 50 mph ahead of an approaching cold front will create\n> widespread critical fire weather conditions Friday afternoon through\n> Friday evening. Southwest winds increase over northeastern Wyoming\n> after 10 am Friday morning with sustained winds of 25 to 35 mph and\n> gusts of 40 to 50 mph through the afternoon. Winds will shift to the\n> northwest after midnight as the front moves through. While some\n> showers may accompany the front, not expecting any widespread wetting\n> rains.\n>\n> \\* AFFECTED AREA...Fire Weather Zones 314, 315, 316, 317, 318, 323,\n> and 327.\n>\n> \\* TIMING...Until 11 PM MDT this evening.\n>\n> \\* WINDS...Southwest winds 25 to 35 mph with gusts up to 50 mph.\n>\n> \\* RELATIVE HUMIDITY...As low as 13 percent.\n>\n> \\* IMPACTS...Any fires that develop will spread rapidly. Outdoor\n> burning is not recommended.\n\nThe protective-action text the issuing office attached, reproduced without changes:\n\n> A Red Flag Warning means that critical fire weather conditions are\n> either occurring now, or will shortly. A combination of strong winds,\n> low relative humidity, and warm temperatures can contribute to\n> extreme fire behavior.\n\nThe National Weather Service superseded this message at Oct. 23, 2026, 8:52 p.m. MDT / 9:52 p.m. CDT 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. 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.
