Inspired by Tygart Media Storm Tracker — Storm Updates: New Mexico Flood Moderate, Western Dakotas Marginal — Wednesday, September 23, 2026 — https://tygartmedia.com/storm-updates-september-23-2026-new-mexico-flood-western-dakotas-marginal/.
What changed since the morning companion: still no convective watches and still no mesoscale discussions. SPC 2000 UTC (issued 2:58 p.m. CDT) cut the Day 1 Marginal to the western Dakotas only — Dickinson, North Dakota; Belle Fourche, South Dakota; Sidney, Montana — and added a CIG 1 contour for isolated 2-inch hail if a transient supercell holds. The southern Appalachians 5% wind contour from the 1300 UTC package is off the 2000 UTC map. WPC Day 1 still holds Moderate excessive rain on central and eastern New Mexico through 12Z Thursday; Slight remains on southeast Arizona, a slice of far west Texas, and eastern Kentucky / eastern Tennessee / far western North Carolina. Live ticket since morning: NWS Albuquerque flash-flood warning this morning on the South Fork burn scar in south-central Lincoln County (Brady, Bear, Perk, Cedar Creek, Eagle Creek, Rio Ruidoso). Flood watches still run this evening into late tonight across central and eastern New Mexico and the Tularosa Basin / Alamogordo / Doña Ana corridor. Today’s 12Z–now LSR window is empty — no tornado, hail, or wind reports yet. Do not invent them. Tropical Storm Nolo now carries a Hurricane Watch for Hawaii County; land threat is Friday–Saturday on the Big Island, not a CONUS landfall. Morning pulse stays up at the Wednesday morning companion.
Owner / Principal
Keep overtime and extra equipment on the New Mexico water desk. The Moderate risk did not expire at 20Z. Training cells, burn-scar debris flow, and arroyo failure remain the multi-day problem through Thursday morning. Do not fund a national CAT off a trimmed Dakotas Marginal and an empty afternoon LSR board. Do not pull crews off Lincoln, Otero, Socorro, or Doña Ana for Dickinson or Belle Fourche. Appalachians are leftover water on wet soils, not a new severe overlay — pay overnight El Paso, Amelia/Powhatan, and western North Carolina interiors already on the mold clock. Hawaii County is a Friday NHC re-check, not today’s CONUS roll. Polo and Odalys stay off the mainland board.
GM / Ops
Rebuild the board around the 20Z cut. Column A — live water: central and eastern New Mexico flood watches plus the South Fork burn-scar drainages. On-call through Thursday 12Z. Stage pumps and air movers before the next training band. Do not strip a quiet commercial dry-in in another state to chase the Moderate polygon before water is on the floor. Column B — isolated hail/wind only if you already cover western North Dakota, the Black Hills, or far eastern Montana. Late afternoon into early evening. No watch. Column C — second water desk: WPC Slight on eastern Kentucky, eastern Tennessee, and far western North Carolina; WPC Marginal Ohio into West Virginia and western Virginia/North Carolina. Confirm the live county product before a truck leaves I-40 or I-81. South Florida stays urban ponding. Empty LSR board after 12Z is not permission to invent a wind line.
Project Manager
New Mexico first four hours tonight: exterior set only if the crossing is passable, then extract before tarp when water is already inside. Occupied homes get contents protection and a category call before any wall opens. Vacant commercial can dry-in once power is confirmed. Burn-scar runoff is rock, mud, and vegetation into reservoirs, bridges, culverts, and the Rio Ruidoso — log the road and the drainage, not just the living room. Dakotas cells after mid-afternoon: photo first, tarp versus extract based on whether the roof is open. Do not batch a Sidney address from a Dickinson radar grab. Appalachian leftover interiors still log Monday–Tuesday wind-driven rain separately from today’s street and creek water. Do not open walls until the moisture map is locked. Hawaii County gets no CONUS pack-out plan from this pulse.
Estimator
Four files, not one outlook. Water: New Mexico Moderate plus the Lincoln County burn-scar warning — extraction, drying, debris-flow cleanup, and a 24–48 hour mold-clock line even when the shingles look intact. Do not price a rebuild from a flooded-arroyo photo. Wind/hail: western Dakotas only if a cell verifies at an address you already work — density, fracture, soft metal, and isolated siding. CIG 1 is a conditional 2-inch note, not a countywide award. Appalachians: residual-plus-today water, not a new CAT. Yesterday’s Alabama and Texas wind LSRs stay on yesterday’s files. Leave ALE for occupied residential after livability is known. Do not fold an expired Amelia/Powhatan warning into an Alamogordo estimate. Do not write Nolo as a Gulf or Atlantic landfall on a scope.
Technician
Meter and category before any wall opens. New Mexico flood water is category 2 until the source is proven clean — burn-scar runoff and street flood are not automatically category 1. PPE stays on for still-draining interiors. Outage blocks: electrical safety first; generators stay outside and downwind; do not run air movers on an unverified panel. Do not start insulation removal until the PM signs the map. Dakotas afternoon cores hide hail in gutters and soft metal — photograph before discard. Appalachian leftover interiors are wet-ground flash flood and prior tree work, not a basement surprise you treat as clean. Turn around, don’t drown on low-water crossings and arroyos in central and eastern New Mexico tonight.
Business Development
Call the people under a live product, not the morning Appalachians Marginal that SPC just removed. Commercial managers in Lincoln, Socorro, Otero, Doña Ana, Alamogordo, and El Paso get a short after-hours note — dock wells, elevator pits, roof drains, overnight access, burn-scar crossings. Residential adjusters on those ZIPs get a daylight photo window, not a neighborhood blast. Western Dakotas commercial and ranch accounts only if you already sit in Dickinson, Belle Fourche, or Sidney — “on call if a warning posts” is enough. Eastern Tennessee and far western North Carolina get leftover-water checks, not a severe-storm blast. Skip social for Nolo as a mainland hurricane. Skip Polo and Odalys. Do not pitch. Do not name clients.
Commercial vs Residential
The split is still water versus isolated wind, and the water side still owns the afternoon. New Mexico commercial is warehouse drains, dock wells, elevator pits, and plant yards while the overnight shield organizes; residential in the same counties is contents, occupied livability, ALE if the house is unlivable, and rural crossings that fail first on burn scars. Far west Texas is the eastward leak of the same plume. Western Dakotas commercial, if a cell verifies, is membrane, HVAC, and glass on a thin footprint; residential is trees on service drops and soft metal — not a contents pack-out line. Appalachian commercial is below-grade electrical on wet soils; residential is basement contents and the mold clock from earlier pulses. Hawaii County commercial and residential both wait on Friday’s NHC package. Do not send one crew from a Ruidoso extraction to a Dickinson tarp without checking which county still has a product.
